   > @matteosal Are you sure that your $mkl_dir path is proper one? In my environment I have
   > -DMKL_INCLUDE_DIR=/home/bg/miniconda3/envs/mxnet/**include**
   > -DBLAS_LIBRARIES="/home/bg/miniconda3/envs/mxnet/**lib**/libmkl_def.so;

   >     /home/bg/miniconda3/envs/mxnet/**lib**/libmkl_core.so;
   >     /home/bg/miniconda3/envs/mxnet/**lib**/libmkl_intel_thread.so;
   >     /home/bg/miniconda3/envs/mxnet/**lib**/libiomp5.so"

   Yes that's because for some reason our reference internal MKL checkout has a non-standard file layout, all includes and libraries are dumped into the same folder (`$mkl_dir` in my script). 
   If there was a problem with this it would have failed at build time, and we have been building and intensively using mxnet with this setup for years. Also I don't see any symbol lookup errors anymore, so I'd rule out that something is wrong with the MKL path.
