Undefined symbol: cblas appears after installing pytorch1.0.0_ sgemm_ Alloc error

Installation of pytorch1.0 encountered the following problems:

>>> import torch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "xxxxx/site-packages/torch/__init__.py", line 84, in <module>
    from torch._C import *
ImportError: xxxxx/site-packages/torch/lib/libmkldnn.so.0: undefined symbol: cblas_sgemm_alloc

Someone on the Internet has solved this problem by opening ~ /. Bashrc and finding the declaration of such a variable:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

Then comment it out and the problem is solved.

But I don’t have such a line when I open the bashrc file
after many searches, I have solved this problem as follows:

conda install -c anaconda mkl

This line of code, and then I import torch succeeded!

Hope to help you!
