Hi, guys, after installing PyTorch 1.0, I am facing the following error:

>>> import torch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "miniconda3/envs/pytorch/lib/python3.6/site-packages/torch/__init__.py", line 84, in <module>
    from torch._C import *
ImportError: miniconda3/envs/pytorch/lib/python3.6/site-packages/torch/lib/libmkldnn.so.0: undefined symbol: cblas_sgemm_alloc

I was not able to find a solution to this error.

Thanks!

I had the same issue and realized I had installed mkl using

conda install -c anaconda mkl

I tried installing

conda install -c intel mkl

and import torch worked.

Hope this helps!

I had the same problem. Do you remember how the problem was solved? Installing WHL is not helpfull.

After installing the transformers library, the torch doesn’t work. The easiest way is to install a new torch version.
