TaoLv commented on issue #11977: Feature request: Enable or Disable MKL-DNN in MXNet via environment variable at module load time URL: https://github.com/apache/incubator-mxnet/issues/11977#issuecomment-409815501 Good idea! Seems we can use environment variables to make one or all mkldnn operators fall back to mxnet original implementation. This can be done simply by changing the SupportXXX function of mkldnn operator? I think this can help to do functionality or performance debug. But performance auto tuning is another topic which need more high level solution.
