ImportError on mac with pytorch 1.1

1

Hi, I just updated the pytorch version from 1.0 to 1.1. When importing pytorch, I was given the following error:

Python 3.6.6 (v3.6.6:4cf1f54eb7, Jun 26 2018, 19:50:54)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.4.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import torch

Any suggestion to fix it?

Thanks,

You may need to install libomp. There was a similar issue discussed on GitHub.
