Cannot generate op.h when build with mkl


#1
  • os : windows 10 64bits
  • compiler : vc2015 64bits update 3
  • mxnet : 1.3.1

I write down the steps of building at stackoverflow, please read it until step 14 if you want to know the details.

I use python download from here to generate op.h, but it throw error message

Dependency of libmxnet.dll(by dumpbin)

mkl_rt.dll
KERNEL32.dll
VCOMP140.DLL

Dependency of mkl_rt.dll(by dumpbin)

KERNEL32.dll

I put both of the dll, mkl_rt.dll and libmxnet.dll into a folder could be found by the os, try to generate op.h again, but it still give me the same error, how could I solve this issue? Thanks

ps : Use Anaconda3 can generate op.h, but it cause another issue " Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll."


#2

Solve this issue, the reason is I am using python with 32 bits, unfortunately using another version of python do not solve another issue " Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll. "
