TaoLv commented on issue #15419: Can't install mxnet with mkldnn,Error: undefined symbol: mkldnn_primitive_desc_query_memory_d URL: https://github.com/apache/incubator-mxnet/issues/15419#issuecomment-507271939 Great to hear it works now! In order to see MKL-DNN verbose log, you need: 1. export MKLDNN_VERBOSE=1 2. make sure MKL-DNN operator/primitive is invoked. I can see MKL-DNN verbose log on my side: ``` export MKLDNN_VERBOSE=1 python train_mnist.py /home/lvtao/.local/lib/python2.7/site-packages/h5py/__init__.py:34: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated.
