zheng-da commented on issue #10921: Test cases improvement for MKLDNN on Gluon URL: https://github.com/apache/incubator-mxnet/pull/10921#issuecomment-388640918 @marcoabreu i agree with you that we need cpp tests for MKLDNN to explicitly cover different input and output NDArrays. I'm writing such unit tests. These tests will cover more different cases and many of them are not covered by the python unit tests. However, writing such cpp unit tests is much more difficult and probably can only be used for testing a single operator. We'll need more people to write unit tests. The tests on in this PR. https://github.com/apache/incubator-mxnet/pull/10651 I'll probably split the PR and submit another PR for adding cpp unit tests. That's why the python tests can be useful. It can easily cover many different operator combinations, which may cause problems in MKLDNN and was never tested in our unit tests.
