performance advisor: lwi_me.py cmd errors before starting capture

Nikos Sfikas

Hello,

I am trying to run the lwi_me.py script in the console with the 'python3 lwi_me.py --lwi-api=vulkan' line inside the helpers directory(python 3.10 installed) and also, as it seems I can capture in the streamline alone and without running the script that exits with an error code.

What do I get when I run the python script in the console ->

Any ideas / known issue / happened to anyone else before?

I would love to know. Thanks in advance.
