Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so

Question

I am running a python script and I get this error:

Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so.

Both files are present

Answer 1

try export LD_DEBUG=libs and execute your program again.

It will tell you which .so is causing the problem.

Then you can do something, e.g. upgrading the package.

For me, I find upgrade numexpr useful as it prints the following message just before the error:

calling init: xxxxx/python3.6/site-packages/numexpr/interpreter.cpython-36m-x86_64-linux-gnu.so
