             Summary: Need add unit-test to monitor data format change of MKL-DNN
                 Key: MXNET-98
                 URL: https://issues.apache.org/jira/browse/MXNET-98
             Project: Apache MXNet
          Issue Type: Test
            Reporter: Tao Lv


Since we have built a [mapping|https://github.com/apache/incubator-mxnet/blob/master/src/operator/nn/mkldnn/mkldnn_base.cc#L193] from MKL-DNN data format to MXNet default data format, say mkldnn_nChw8c and mkldnn_nChw16c will both map to nchw. If new data format is added to MKL-DNN, this kind of mapping will be broken. We need set a dedicated unit-test to monitor the change of MKL-DNN data format. If the test case fails, we should check this piece of code to see if we need adjust it to handle new data format properly.

Since MKL-DNN lists all supported data formats in an enum type. It's a little difficult to monitor the change of enum type at mxnet side. We have asked MKL-DNN team to add support for that. Will finish this unit-test after getting response from MKL-DNN team.
