MKL warning (undefined symbol: mkl_get_version_string)

I was pointed here since a downstream project (fil profiler) said that this was a bug in threadpoolctl, but I think the library isn’t able to handle our MKL version:

Traceback (most recent call last):
  File "_ctypes/callbacks.c", line 232, in 'calling callback function'

AttributeError: /usr/local/lib/libmkl_rt.so: undefined symbol: mkl_get_version_string

I’m pretty sure the MKL version (as defined by INTEL_MKL_VERSION) is 20190004 if that helps.

Just to be safe, use grep -i (ignore case):

nm --demangle /usr/local/lib/libmkl_rt.so | grep -i "version"

What do you get listing symbols? You can do so and filter on version using : nm --demangle /usr/local/lib/libmkl_rt.so | grep “version”

Also, can you tell us the result of nm --demangle /usr/local/lib/libmkl_rt.so | grep "Version". I suspect you only have the MKL_Get_Version_String symbol.
