UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 11: invalid start byte****

[besn0847]

Hi,

I'm using CUDA 12.1 and installed [bitsandbytes-0.41.2.post2] but i get a UnicodeDecodeError when i run 'python -m bitsandbytes'.
Any idea what is going on ?

Below the error message

Cheers

Same here !'utf-8' codec can't decode

[axel578]

I modified bitsandbytes site packcakge code with try and except, except it return ('','') for the function with _decode, and it seams to be okay, just not, the command failing is :
where /R "C:\Users\myuser\Desktop\AI\3D\mypythonproject" "cudadll"

Why is it looking for cuda dll in my python folder ????? of course it won't find anything, note, this folder is nowhere in environment variable
