Cannot re-initialize CUDA in forked subprocess

[bakirillov]

Hello!

Auto-Pytorch fails with the following error:
Cannot re-initialize CUDA in forked subprocess. To use CUDA with multiprocessing, you must use the 'spawn' start method

What am I doing wrong?

Found out the solution. Just don't use your GPU anywhere else in python, it creates conflict.

In the master-old branch it is mentioned that " ... Disable pynisher if you experience issues when using cuda ...". In my case disabling pynisher solved the issue.
