[GitHub] [incubator-mxnet] mseth10 opened a new issue #18889: Caching subgraphs based on input shapes
mseth10 opened a new issue #18889:
URL: https://github.com/apache/incubator-mxnet/issues/18889
## Description
When a graph containing dynamic shape op is partitioned based on #18887 (and #18888 ) , the new computation graph contains dynamic shape ops and subgraphs containing static shape ops. The input shapes to these subgraphs can vary for two graph inputs of same shape. This is possible because a dynamic shape op can produce different output shapes for two inputs of same shape, and output of such a dynamic shape op can be an input to a static shape subgraph. Thus, graph optimization techniques like shape inference and memory allocation cannot necessarily be reused from one input to another. A caching of such an optimized subgraph based on input shape is necessary to get performance boost for some inputs.
