Referring to fig. 1, the processing method may include: step S11 to step S13.
And step S11, determining all target operator nodes in the neural network calculation graph according to the output connection relations of the operator nodes, wherein the target operator nodes are provided with a first output end and a second output end, and the operator nodes connected with the first output end are data output nodes.
And step S12, taking the second output end of the target operator node as a splitting point, splitting the neural network computation graph into a plurality of computation subgraphs connected in series, wherein the output end of the operator node connected with the second output end is connected with other operator nodes.
And step S13, sequentially generating an executable file corresponding to each computation subgraph according to each computation subgraph.
In this embodiment of the present disclosure, for a to-be-processed neural network computational graph, before determining all target operator nodes in the neural network computational graph according to the output connection relationships of the plurality of operator nodes, that is, before step S11, the processing method further includes: and acquiring node information of each operator node in the neural network computational graph.
The node information of the operator node may include an input connection relationship, an output connection relationship, required parameter information, attribute information of the operator node, an execution order of the operator node, and the like of the operator node. The input connection relation of the operator node is used for describing the connection relation between the input of the operator node and the output of other operator nodes in the neural network computation graph, the output connection relation of the operator node is used for describing the connection relation between the output of the operator node and the input of other operator nodes in the neural network computation graph, parameter information required by the operator node comprises but is not limited to a weight parameter which is configured in advance and is required for realizing the operation of the operator node, attribute information of the operator node is information for representing the characteristic attribute of the operator node, the attribute information of the operator node can comprise but is not limited to the operator type of the operator node, the calculation amount and the storage amount required by the operator node, and the execution sequence of the operator node is the time sequence for representing the operation of the operator node.
In step S11, according to the output connection relationship of the plurality of operator nodes in the neural network computation graph, so as to have a first output end and a second output end, and the result output by the first output end is a part of the output result of the neural network computation graph as a filtering condition, all target operator nodes in the neural network computation graph that satisfy the filtering condition can be determined.
Specifically, for each operator node in the neural network computational graph, according to the output connection relationship of the operator node, the number of other operator nodes connected to the output of the operator node in the neural network computational graph can be determined, so as to determine the number of output branches of the operator node, that is, determine that the operator node is a single output node, a double output node, or a multiple output node.
Further, according to the output connection relations and node information of the operator nodes in the neural network computation graph, the output connection relations and the operator types of other operator nodes connected with each output end of each operator node can be determined, whether the other operator nodes connected with each output end of each operator node are data output nodes is further determined, and whether each operator node is a target operator node is further determined. The data output node refers to an operator node of which the operator type is used for outputting data, the output data is used as a part of an output result of the neural network computational graph, and the operator node of the operator type is not used for data operation and does not have an output connection relation with other operator nodes.
When one operator node is a double-output or multi-output node, the operator node connected with one output end of the operator node does not have an output connection relation with other operator nodes, the operator node connected with the one output end is used as a data output node, and the operator node connected with the other output end of the operator node has an output connection relation with other operator nodes, namely the operator node connected with the other output end is a data operation node and is used for carrying out data operation, the output result of the operator node is shown to be used as a part of the output result of the neural network computation graph and also used as the input of the subsequent operator node, so that the operator node meets the screening condition of the target operator node, and the operator node is determined to be the target operator node. Meanwhile, for the sake of distinction, the one input terminal of the operator node is defined herein as a first output terminal, and the other input terminal of the operator node is defined herein as a second output terminal.
Fig. 2 is a schematic structural diagram of a neural network computational graph, for example, referring to fig. 2, operator node 1 is a single output node, and does not meet the screening condition of the target operator node; the operator node 2 is a double-output node, the operator node 3 connected with the first output end 21 of the operator node 2 does not have an output connection relation with other operator nodes, the operator node 3 is a data output node, and the output end of the operator node 4 connected with the second output end 22 has an output connection relation with other operator nodes 6, so that the operator node 2 meets the screening condition of the target operator node; similarly, operator nodes 5 and 7 are both data output nodes, so operator 4 and operator node 6 both satisfy the screening condition of the target operator node, and other operator nodes do not satisfy the screening condition of the target operator node. Therefore, the operator nodes 2, 4, and 6 in the neural network computation graph shown in fig. 2 are respectively used as a target operator node.
In step S12, the neural network computation graph is split with the second output end of each target operator node as a splitting point, so that a plurality of computation subgraphs connected in series can be obtained. Illustratively, taking the neural network computation graph shown in fig. 2 as an example, according to step S11, it may be determined that target operator nodes satisfying the above-mentioned screening condition in the neural network computation graph shown in fig. 2 include operator node 2, operator node 4 and operator node 6, and the neural network computation graph shown in fig. 2 is split by taking second output end 22 of operator node 2, second output end 42 of operator node 4 and second output end 62 of operator node 6 as splitting points, respectively, to obtain 4 computation subgraphs connected in series, assuming that the 4 computation subgraphs are respectively denoted as computation subgraph 1, computation subgraph 2, computation subgraph 3 and computation subgraph 4, the computation subgraph 1 includes operator node 1, operator node 2 and operator node 3, the computation subgraph 2 includes operator node 4 and operator node 5, the computation subgraph 3 includes operator node 6 and operator node 7, the computational graph 4 comprises operator nodes 8 and operator nodes 9.
It should be noted that the number of the first input ends of the target operator node may be one, and the number of the second input ends may be one or more, which is not limited in this disclosure.
For the multiple computation subgraphs split by step S12, each computation subgraph has one or more operator nodes respectively.
In step S13, for each computation subgraph obtained by splitting in step S12, an executable file corresponding to the computation subgraph is generated according to the computation subgraph, where the executable file is an execution code executable on a corresponding chip, so that compiling the computation subgraph to the corresponding chip is realized, and the corresponding chip executes a computation task corresponding to the computation subgraph.
According to the technical scheme of the processing method of the neural network computational graph provided by the embodiment of the disclosure, on one hand, the processing method is suitable for any neural network computational graph, and can realize automatic splitting of any neural network computational graph, so that the neural network computational graph can be compiled in a segmented manner, the compiling difficulty of the neural network computational graph is reduced, the compiling efficiency and effect of the neural network computational graph are improved, the requirement of compiling of the neural network computational graph on chip hardware storage resources is effectively reduced, the problem that the storage resources required by compiling of the neural network computational graph are large and the actual chip hardware storage resources cannot be met is favorably solved, the reasonable utilization of the chip hardware storage resources is realized, and the utilization efficiency of the chip hardware storage resources is improved; on the other hand, the output of each computation subgraph obtained by automatic splitting is used as a part of the output result of the neural network computation graph, and can be stored in an external memory or a host corresponding to the chip without being stored on the chip or being stored on the chip for a long time, so that on-chip storage resources can be effectively saved, and the utilization rate of the on-chip storage resources is improved.
In some embodiments, after sequentially generating an executable file corresponding to each computation subgraph from each computation subgraph, the processing method further comprises: loading the executable file corresponding to each computer subgraph to the corresponding chip; and responding to the completion of the running of the executable file corresponding to the computation subgraph on the chip, and storing the output result corresponding to the computation subgraph to an external memory or a host corresponding to the chip.
The output result corresponding to the computation subgraph is stored in an external memory or a host corresponding to the chip, and the output result corresponding to the computation subgraph is read from the external memory (such as a double-rate synchronous dynamic random access memory) or the host to the chip when needed, so that the on-chip storage resource of the chip can be effectively saved.
Fig. 3 is a schematic flowchart of a specific implementation manner of step S11 in fig. 1, and referring to fig. 3, in some embodiments, in step S13, sequentially generating a chip executable file corresponding to each computation sub-graph according to each computation sub-graph, where the method may further include: step S31 to step S32.
Step S31, in response to failure error reporting occurring when generating the executable file corresponding to the current computation subgraph, further splitting the current computation subgraph into a plurality of serially connected computation subgraphs.
And step S32, sequentially generating an executable file corresponding to each sub-graph obtained by further splitting according to each sub-graph obtained by further splitting.
In step S31, a failure error occurs when the executable file corresponding to the current computation subgraph is generated, which indicates that the current computation subgraph cannot be supported by the corresponding chip and cannot normally run on the corresponding chip, that is, the corresponding chip cannot support the compilation and execution of the current computation subgraph on the chip, for example, the computation power, the computation amount, or the storage amount required by the current computation subgraph exceeds the limit of the corresponding chip, which causes a failure error when the executable file corresponding to the generated computation subgraph occurs, so that the current computation subgraph is further split into multiple computation subgraphs connected in series.
In some embodiments, the current computational sub-graph may be further split in the splitting manner described in steps S11 and S12 above. In some embodiments, the current computation sub-graph may be further split by configuring another splitting manner as needed, or the current computation sub-graph may be further split by configuring another splitting manner and combining the splitting manner described in the foregoing step S11 and step S12, or the current computation sub-graph may be further split manually. The other splitting manner may be, for example, a manner of screening and splitting the target operator node according to other screening conditions of the configured target operator node, and the embodiment of the present disclosure does not specifically limit the manner of further splitting the current computational graph.
For the multiple computational subgraphs further split by step S31, each computational subgraph may have one or more operator nodes, respectively.
In step S32, for each computation subgraph obtained by further splitting in step S31, an executable file corresponding to the computation subgraph is generated according to the computation subgraph, where the executable file is an executable code executable on a corresponding chip, so as to implement compiling the computation subgraph to run on the corresponding chip, so that the corresponding chip executes a computation task corresponding to the computation subgraph.
Through the steps S31 and S32, a failure error is reported when the executable file corresponding to the current computational subgraph is generated, which indicates that the current computational subgraph may not be supported by the corresponding chip, so that the current computational subgraph is further divided and split, thereby improving the compiling effect, facilitating each segment of the obtained computational subgraph to be supported by the chip hardware, and utilizing the hardware resources of the chip as much as possible, and improving the execution efficiency of the chip for processing the neural network computational graph.
Fig. 4 is a flowchart illustrating another specific implementation manner of step S13 in fig. 1, and referring to fig. 4, in some embodiments, in step S13, sequentially generating a chip executable file corresponding to each computation subgraph according to each computation subgraph, the method may further include: step S41 to step S42.
Step S41, in response to no failure error report when generating the executable file corresponding to the current computation subgraph, taking the current computation subgraph as a target computation subgraph;
and step S42, loading the executable file corresponding to each target computation subgraph to the corresponding chip.
In step S41, no failure error is reported when the executable file corresponding to the current compute subgraph is generated, which indicates that the current compute subgraph can be supported by the corresponding chip and can run normally on the corresponding chip, that is, the corresponding chip supports the current compute subgraph to be compiled and executed on the chip, so that the current compute subgraph can be used as the target compute subgraph without further processing the current compute subgraph, and step S42 is executed.
In step S42, since no failure error occurs when the executable file corresponding to the target computation sub-graph is generated, the executable file of the target computation sub-graph can be supported by the corresponding chip and can be normally executed on the corresponding chip, and therefore, for each target computation sub-graph, the executable file corresponding to the target computation sub-graph can be loaded to the corresponding chip to run the executable file corresponding to the target computation sub-graph on the corresponding chip to perform the corresponding computation task.
It should be noted that the computation subgraph obtained by splitting in step S12 and the computation subgraph obtained by further splitting in step S31 are both subgraphs in the neural network computation graph, and therefore, in the embodiment of the present disclosure, specific distinction in name and definition is not made between the computation subgraph obtained by splitting in step S12 and the computation subgraph obtained by further splitting in step S31, identities and functions of the computation subgraph and the computation subgraph are substantially equal, and for specific description of generating an executable file in step S32, reference may be made to related description of generating an executable file in step S13 in the embodiment of the present disclosure, which is not described in detail herein.
In the embodiment of the present disclosure, no failure error report occurs when the executable file corresponding to each computation subgraph is generated, which indicates that all computation subgraphs can be supported by the corresponding chip and can normally operate on the corresponding chip, but there may exist a situation that a part of computation subgraphs actually require less resources and a part of computation subgraphs actually require more resources, and when the executable files of all computation subgraphs are directly loaded on the corresponding chip to operate, it may cause that the chip hardware resources cannot be reasonably utilized, resulting in that the load of part of the chip hardware resources is lower, and the load of part of the chip hardware resources is higher, which is not beneficial to the load balance of the chip hardware resources, therefore, in some embodiments, in order to achieve the reasonable utilization of the chip hardware resources, improve the utilization efficiency of the chip hardware resources, achieve the load balance of the chip hardware resources, after the part of computation subgraphs need to be fused and spliced into one computation subgraph, and generating corresponding executable files and loading the executable files to corresponding chips.
Fig. 5 is a schematic flowchart of another processing method of a neural network computation graph according to an embodiment of the present disclosure, and referring to fig. 5, in some embodiments, after an executable file corresponding to each computation sub-graph is sequentially generated according to each computation sub-graph, that is, after step S13, the processing method may further include: step S51 to step S54.
And step S51, responding to no failure and error report when the executable file corresponding to each computation subgraph is generated, acquiring at least one group of computation subgraphs, wherein each group of computation subgraphs comprises at least two computation subgraphs which are connected in series.
And step S52, performing fusion processing on at least two computation subgraphs in each group of computation subgraphs to obtain alternative computation subgraphs corresponding to each group of computation subgraphs.
And step S53, taking the alternative computation subgraph as the target computation subgraph under the condition that no failure and error are reported when the executable file corresponding to the alternative computation subgraph is generated.
And step S54, loading the executable file corresponding to each target computation subgraph to the corresponding chip.
In step S51, in order to achieve reasonable utilization of chip hardware resources, improve utilization efficiency of chip hardware resources, and achieve load balancing of chip hardware resources, when no failure error report occurs during generation of an executable file corresponding to each computation subgraph, at least one group of computation subgraphs is first obtained from all computation subgraphs connected in series in sequence, where each group of computation subgraphs includes at least two computation subgraphs connected in series.
Exemplarily, referring to the neural network computation graph shown in fig. 2, assuming that the neural network computation graph shown in fig. 2 is currently split into computation subgraph 1, computation subgraph 2, computation subgraph 3 and computation subgraph 4, in step S51, a set of computation subgraphs may be obtained, which may include, for example, computation subgraph 1 and computation subgraph 2 connected in series, or computation subgraph 2 and computation subgraph 3 connected in series, or computation subgraph 2, computation subgraph 3 and computation subgraph 4 connected in series.
In step S52, the fusion process is to connect the output of the previous computational subgraph and the input of the next computational subgraph in every two adjacent computational subgraphs in a group of computational subgraphs in a one-to-one correspondence, so as to merge at least two computational subgraphs in a group of computational subgraphs into one computational subgraph as a candidate computational subgraph.
Exemplarily, referring to the neural network computation graph shown in fig. 2, a group of computation subgraphs includes computation subgraph 1 and computation subgraph 2 connected in series, computation subgraph 1 includes operator node 1, operator node 2 and operator node 3, computation subgraph 2 includes operator node 4 and operator node 5, and in step S52, the computation subgraph 1 and the computation subgraph 2 connected in series are fused to obtain an alternative computation subgraph, where the alternative computation subgraph includes operator node 1 to operator node 5.
After the candidate computational subgraphs obtained by fusing each group of computational subgraphs are processed, corresponding executable files can be generated according to the candidate computational subgraphs obtained by fusing, in step S53, when no failure error report occurs when the executable files corresponding to the candidate computational subgraphs obtained by fusing are generated, it indicates that the candidate computational subgraphs obtained by fusing can still be supported by a corresponding chip and can normally operate on the corresponding chip, that is, the corresponding chip can support at least two computational subgraphs corresponding to one group of computational subgraphs to be compiled and executed on the chip, so that the candidate computational subgraphs can be used as target computational subgraphs.
In some embodiments, for any group of computation subgraphs, when the group of computation subgraphs includes at least two computation subgraphs connected in series and an error occurs in failure and error reporting when an executable file corresponding to a candidate computation subgraph obtained by fusion processing is generated, it indicates that a corresponding chip cannot support compilation execution of the at least two computation subgraphs of the group of computation subgraphs on the chip, and therefore, the at least two computation subgraphs in the group of computation subgraphs before the fusion processing can be respectively used as a target computation subgraph.
For example, assuming that the group of computation subgraphs acquired in step S51 includes a computation subgraph a and a computation subgraph B, a candidate computation subgraph C is obtained after the fusion processing, and when a failure error occurs when generating an executable file corresponding to the candidate computation subgraph C obtained by the fusion processing, the computation subgraph a before the fusion processing may be used as a target computation subgraph, and the computation subgraph B before the fusion processing may be used as a target computation subgraph.
In some embodiments, for any group of computation subgraphs, in the case that the group of computation subgraphs includes multiple (e.g., 3 or 4) computation subgraphs connected in series and a failure error occurs when generating an executable file corresponding to an alternative computation subgraph obtained by fusion processing, the group of computation subgraphs may be further divided into one or more groups of computation subgraphs and the operations in steps S52 and S53 described above are performed, and the computation subgraphs not divided into groups may be respectively used as one target computation subgraph.
For example, assuming that the group of computed subgraphs obtained in step S51 includes a computed subgraph D, a computed subgraph E, and a computed subgraph F, after the fusion processing, a candidate computed subgraph G is obtained, and when an executable file corresponding to the candidate computed subgraph G obtained by the fusion processing is generated and a failure error occurs, the computed subgraph D and the computed subgraph E may be re-partitioned into a group of computed subgraphs, and the computed subgraph D and the computed subgraph E are subjected to the fusion processing again, and the fused subgraph is subjected to the operation in step S53, but the computed subgraph F is not partitioned into a group, and the computed subgraph F is solely used as a target computed subgraph.
In addition, reference may be made to the above description of step S42 for the description of step S54, and details are not repeated here.
In some embodiments, in step S51, obtaining at least one set of computational subgraphs may further include: determining at least one group of computational subgraphs which can be subjected to fusion processing in all the computational subgraphs according to the subgraph attribute parameters corresponding to the computational subgraphs; the subgraph attribute parameters corresponding to the computational subgraph can include the computation amount corresponding to the computational subgraph, weight information and the number of nodes of the corresponding vector acceleration unit graph.
Wherein, the computation amount corresponding to the computation subgraph can be the sum of the computation amounts required by all the operator nodes contained in the computation subgraph, the weight information corresponding to the computational subgraph may comprise the sum of the weight sizes required for computing all the operator nodes contained in the subgraph, the method comprises the steps of mapping a neural network computation graph to specific chip hardware in advance before splitting the neural network computation graph to obtain a vector acceleration unit (APU) graph corresponding to the neural network computation graph, wherein the vector acceleration unit (APU) graph corresponding to the neural network computation graph characterizes the mapping relation of operator nodes of the neural network computation graph on the specific chip hardware (such as a many-core chip and a physical core on the chip), and correspondingly, the vector acceleration unit (APU) graph corresponding to a computation subgraph split from the neural network computation graph characterizes the mapping relation of the operator nodes of the computation subgraph on the specific chip hardware.
In some embodiments, the step of determining at least one group of computational subgraphs capable of performing fusion processing in all the computational subgraphs according to the subgraph attribute parameters corresponding to the computational subgraphs may further include: according to the serial connection relation and the execution sequence of all the computation subgraphs, sequentially checking whether at least two computation subgraphs in serial connection meet the fusion condition; and when the at least two serially connected computer subgraphs meet the fusion condition, taking the at least two computer subgraphs as a group of computer subgraphs.
Wherein the fusion condition may include: the sum of the calculated amount corresponding to the at least two calculated subgraphs is greater than or equal to a minimum calculated amount threshold value and less than or equal to a maximum calculated amount threshold value; the sum of the weight information corresponding to the at least two computation subgraphs is greater than or equal to a minimum weight threshold value and is less than or equal to a maximum weight threshold value; the sum of the number of nodes of the APU graph corresponding to the at least two computation subgraphs is greater than or equal to a minimum number threshold and less than or equal to a maximum number threshold.
The minimum calculation threshold and the maximum calculation threshold may be configured according to actual needs, and similarly, the minimum weight threshold and the maximum weight threshold may also be configured according to actual needs, and the minimum number threshold and the maximum number threshold may also be configured according to actual needs.
For example, assuming that all current computation subgraphs include a computation subgraph H, a computation subgraph I, a computation subgraph J, a computation subgraph K and a computation subgraph L which are sequentially connected in series, when it is determined that the computation subgraph H and the computation subgraph I which are connected in series satisfy the above-mentioned fusion condition, the computation subgraph H and the computation subgraph I which are connected in series are taken as a group of computation subgraphs, and when it is determined that the computation subgraph J, the computation subgraph K and the computation subgraph L which are connected in series satisfy the above-mentioned fusion condition, the computation subgraph J, the computation subgraph K and the computation subgraph L which are connected in series are taken as a group of computation subgraph.
In some embodiments, the at least two serially connected computer subgraphs capable of being fused are judged according to the fusion condition, so that the efficiency of obtaining at least one group of computer subgraphs capable of being fused can be improved, the compiling effect of the fused subgraphs is improved, and the probability of failure and error reporting of the generated fused subgraphs is reduced.
In some embodiments, in step S51, obtaining at least one set of computational subgraphs may further include: and according to the serial connection relation and the execution sequence of all the computation subgraphs, respectively taking every two serially connected computation subgraphs in all the computation subgraphs as a group of computation subgraphs.
For example, assuming that all current computation subgraphs include a computation subgraph H, a computation subgraph I, a computation subgraph J and a computation subgraph K which are serially connected in sequence, the serially connected computation subgraph H and computation subgraph I are used as a group of computation subgraphs, and the serially connected computation subgraph J and computation subgraph K are used as a group of computation subgraphs.
In some embodiments, by directly taking every two serially connected computation subgraphs in all the computation subgraphs as a group of computation subgraphs, the efficiency of obtaining at least one group of computation subgraphs can be effectively improved.
Fig. 6 is a schematic flowchart of another processing method of a neural network computation graph according to an embodiment of the present disclosure, and referring to fig. 6, in some embodiments, after an executable file corresponding to each computation sub-graph is sequentially generated according to each computation sub-graph, that is, after step S13, the processing method may further include: step S61 to step S64.
And step 61, in response to no failure and error report when the executable file corresponding to each computation subgraph is generated, merging the current computation subgraph and the next computation subgraph into alternative computation subgraphs according to the direction of the execution sequence of all computation subgraphs.
And step S62, taking the current computation subgraph as the target computation subgraph when failure error reporting occurs when the executable file corresponding to the alternative computation subgraph is generated.
And step S63, taking the next computational subgraph as the current computational subgraph, and returning to the step of fusing the current computational subgraph and the next computational subgraph into an alternative computational subgraph.
And step S64, loading the executable file corresponding to each target computation subgraph to the corresponding chip.
In step S61, when no failure error report occurs during the generation of the executable file corresponding to each computation subgraph, in order to achieve reasonable utilization of chip hardware resources, improve utilization efficiency of chip hardware resources, and achieve load balancing of chip hardware resources, first, according to the execution sequence direction (e.g., the direction from top to bottom in fig. 2) of all computation subgraphs serially connected in sequence, the current computation subgraph and the next computation subgraph are fused to obtain an alternative computation subgraph. The current computation subgraph and the next computation subgraph are two computation subgraphs which are connected in series and adjacent in the neural network computation subgraph, and the next computation subgraph is the next computation subgraph of the current computation subgraph along the execution sequence direction, namely the computation subgraph connected with the output of the current computation subgraph along the execution sequence direction.
For example, referring to the neural network computation graph shown in fig. 2, assuming that the neural network computation graph shown in fig. 2 is currently split into a computation subgraph 1, a computation subgraph 2, a computation subgraph 3 and a computation subgraph 4, and according to the direction of the execution sequence, the current computation subgraph is the computation subgraph 1, in step S61, the computation subgraph 1 and the computation subgraph 2 are first fused to obtain an alternative computation subgraph.
After the candidate computational subgraph is obtained, a corresponding executable file can be generated according to the candidate computational subgraph obtained through the fusion processing, in step S62, when a failure error occurs when the executable file corresponding to the candidate computational subgraph is generated, it is indicated that the candidate computational subgraph obtained through the fusion processing cannot be supported by a corresponding chip and cannot normally run on the corresponding chip, and therefore the current computational subgraph is taken as a target computational subgraph alone and is subjected to step S63 to continue the fusion and judgment according to the execution sequence direction.
In step S63, the next computational sub-graph is taken as the current computational sub-graph, and the step of merging the current computational sub-graph and the next computational sub-graph into the alternative computational sub-graph is executed, that is, the step S61 is executed, so as to continue to merge and judge the current computational sub-graph and the next computational sub-graph of the current computational sub-graph according to the execution sequence direction until all the computational sub-graphs are traversed.
For example, if a failure error is reported when the executable file corresponding to the candidate computational subgraph is obtained by fusing the computational subgraph 1 and the computational subgraph 2 is generated, it indicates that the computational subgraph 1 and the computational subgraph 2 are not suitable for fusion, so that the computational subgraph 1 is taken as a target computational subgraph, the computational subgraph 2 is taken as a current computational subgraph, the computational subgraph 2 and the computational subgraph 3 are continuously fused and judged, and so on until all the computational subgraphs are traversed.
In addition, for the description of step S64, reference may be made to the above description of step S42, which is not repeated herein.

And step S72, taking the alternative computation subgraph as the target computation subgraph under the condition that no failure and error are reported when the executable file corresponding to the alternative computation subgraph is generated.
And step S73, taking the computation subgraph of which the execution sequence is after the next computation subgraph as the current computation subgraph, and returning to execute the step of merging the current computation subgraph and the next computation subgraph into an alternative computation subgraph.
And step S74, loading the executable file corresponding to each target computation subgraph to the corresponding chip.
For the description of step S71, reference may be made to the above description of step S61, which is not repeated herein.
After the candidate computation subgraph is obtained, a corresponding executable file can be generated according to the candidate computation subgraph obtained through the fusion processing, in step S72, under the condition that no failure error report occurs when the executable file corresponding to the candidate computation subgraph is generated, it is indicated that the candidate computation subgraph obtained through the fusion processing can still be supported by a corresponding chip and can normally operate on the corresponding chip, and therefore the candidate computation subgraph is used as a target computation subgraph and is subjected to step S73 to continue the fusion and judgment according to the direction of the execution sequence.
In step S73, the computation subgraph located after the next computation subgraph in the direction of the execution sequence and adjacent to the next computation subgraph is taken as the current computation subgraph, and the step of fusing the current computation subgraph and the next computation subgraph into the alternative computation subgraph is executed, that is, the step S71 is executed again to continue to fuse and judge the current computation subgraph and the next computation subgraph of the current computation subgraph in the direction of the execution sequence until all computation subgraphs are traversed.
For example, assuming that all current computation subgraphs include a computation subgraph H, a computation subgraph I, a computation subgraph J and a computation subgraph K which are sequentially connected in series, the current computation subgraph is the computation subgraph H, the next computation subgraph is the computation subgraph I, and when an executable file corresponding to the alternative computation subgraph is obtained by fusing the computation subgraph H and the computation subgraph I is generated, failure error reporting does not occur, it is indicated that the computation subgraph H and the computation subgraph I are suitable for further fusion, so that the alternative computation subgraph obtained after the computation subgraph H and the computation subgraph I are fused is used as a target computation subgraph, the computation subgraph J is used as the current computation subgraph, the computation subgraph J and the computation subgraph K are continuously fused and judged, and so on until all the computation subgraphs are traversed.
In addition, for the description of step S74, reference may be made to the above description of step S42, which is not repeated herein.
Fig. 8 is a schematic flowchart of another processing method of a neural network computation graph according to an embodiment of the present disclosure, and referring to fig. 8, in some embodiments, after an executable file corresponding to each computation sub-graph is sequentially generated according to each computation sub-graph, that is, after step S13, the processing method may further include: step S81 to step S84.
And step S81, responding to no failure and error report when the executable file corresponding to each computation subgraph is generated, and sequentially fusing two adjacent computation subgraphs according to the execution sequence direction of all the computation subgraphs.
And step S82, sequentially fusing two adjacent computation subgraphs in the direction opposite to the execution sequence direction.
And step S83, regarding any computational subgraph obtained through the fusion processing, taking the computational subgraph obtained through the fusion processing as a target computational subgraph under the condition that no failure and error are reported when an executable file corresponding to the computational subgraph obtained through the fusion processing is generated.
And step S84, loading the executable file corresponding to each target computation subgraph to the corresponding chip.
In step S81, in order to achieve reasonable utilization of chip hardware resources, improve utilization efficiency of chip hardware resources, and achieve load balancing of chip hardware resources when no failure error report occurs during generation of the executable file corresponding to each computation subgraph, first, in step S81, adjacent computation subgraphs are fused according to the execution sequence direction (e.g., the direction from top to bottom in fig. 2) of all computation subgraphs serially connected in sequence, so as to obtain alternative computation subgraphs, and after obtaining each alternative computation subgraph, a corresponding executable file can be generated according to the alternative computation subgraph obtained through the fusion processing.
Meanwhile, in step S82, the adjacent computation subgraphs are fused according to the direction opposite to the above-mentioned execution sequence direction (e.g. the direction from bottom to top in fig. 2), so as to obtain alternative computation subgraphs, and after each alternative computation subgraph is obtained, a corresponding executable file may be generated according to the alternative computation subgraph obtained through the fusion processing.
For example, assume that all the current computation subgraphs include computation subgraph H, computation subgraph I, computation subgraph J, computation subgraph K, computation subgraph L and computation subgraph M connected in series in this order, the direction of execution order is from computation subgraph H to computation subgraph M, and the direction opposite to the direction of execution order is from computation subgraph M to computation subgraph H. In step S81, according to the execution sequence direction, first performing fusion processing on the computational sub-graph H and the computational sub-graph I; at the same time, in step S82, the computation sub-graph M and the computation sub-graph L are first fused in the direction opposite to the execution sequence direction.
After each candidate computational subgraph is obtained, a corresponding executable file can be generated according to the candidate computational subgraph obtained through the fusion processing. In step S83, for the computed subgraph obtained by the fusion processing in any direction, when an executable file corresponding to the candidate computed subgraph obtained by the fusion processing is generated without failure and error reporting, it indicates that the computed subgraph obtained by the fusion processing can still be supported by the corresponding chip and can normally run on the corresponding chip, so that the computed subgraph obtained by the fusion processing is used as a target computed subgraph, and the fusion processing and judgment of two adjacent computed subgraphs are continued simultaneously according to different directions, for example, the computed subgraph J and K are continued to be subjected to the fusion processing and judgment, and so on until all the computed subgraphs are traversed.
In some embodiments, for a computation subgraph obtained by fusion processing in any direction, when a failure error occurs when an executable file corresponding to the computation subgraph obtained by the fusion processing is generated, it indicates that two adjacent computation subgraphs before the fusion processing are not suitable for fusion, so the processing method may further include:
and when the computational subgraph obtained by the fusion processing is the computational subgraph obtained by the fusion processing according to the execution sequence direction, taking the computational subgraph with earlier execution sequence in the two adjacent computational subgraphs before the fusion processing as a target computational subgraph, and continuously performing the fusion processing on the computational subgraph with later execution sequence and the next computational subgraph adjacent to the computational subgraph with later execution sequence according to the execution sequence direction.
And when the computational subgraph obtained by the fusion processing is the computational subgraph obtained by the fusion processing according to the direction opposite to the direction of the execution sequence, taking the computational subgraph with the later execution sequence in the two adjacent computational subgraphs before the fusion processing as a target computational subgraph, and continuously performing the fusion processing on the computational subgraph with the earlier execution sequence and the previous computational subgraph adjacent to the computational subgraph with the earlier execution sequence according to the direction opposite to the direction of the execution sequence.
In addition, for the description of step S84, reference may be made to the above description of step S42, which is not repeated herein.
In some embodiments, trial fusion and judgment are sequentially performed on adjacent computation subgraphs along different directions, so that the efficiency of trial fusion and judgment can be effectively improved.
