Hi MXNet developers, I am working on PR#12953<https://github.com/apache/incubator-mxnet/pull/12953> to update the version of MKL-DNN dependency. This PR will help to address several requests and issues from the commnunity of both MXNet and MKL-DNN. It will also improve MXNet performance a lot when using MKL-DNN backend. Currently, this work is almost done except the failure of LRN CPP test. Since this PR doesn't touch the integration code of MKL-DNN LRN operator, so I guess there is something new in MKL-DNN which has conflict with the CPP test . An internal discussion is ongoing with MKL-DNN developers about that and hopefully this issue will be fixed soon.
I noticed that there are several other CPP tests for MKL-DNN operator are under review and they are following the some methodology of LRN CPP test. To avoid more conflicts, I suggest to hold on the merge of these new tests before the LRN issue in #12953 is clrealy addressed. Here is the list of these PRs: https://github.com/apache/incubator-mxnet/pull/13084 https://github.com/apache/incubator-mxnet/pull/12985 https://github.com/apache/incubator-mxnet/pull/12884 Let me know what do you think. Thanks. -tao
