Hi,

It seems like you are facing a similar issue as the below topic:
https://github.com/numpy/numpy/issues/18131

Could you try the suggestion to see if it also works for you first?
Thanks.

This works for me. However is there a way to make it work without having to constantly type the whole command, and just type python3 instead ? I’m still a newbie into all this and would appreciate any positive feedback. Thanks.

Hi @mpico602, two ways:

  1. Run export OPENBLAS_CORETYPE=ARMV8 in your terminal. It will remain active as long as that terminal remains open.

  2. Add export OPENBLAS_CORETYPE=ARMV8 to your ~/.bashrc. It will set that environment variable on every new terminal that is opened.

Thanks @dusty_nv I tried the second approach and It is now working perfectly.

I pinned the numpy version to something smaller than 1.19.5 as mentioned in the numpy issue thread:

numpy<=1.19.4

and don’t have to set OPENBLAS_CORETYPE=ARMV8 anymore.
