This is the error I get, after trying for an hour all the possible combinations I found in resolved issues, still didn't fix it.

For me what really fixed after done many tries is. pip install --upgrade --force-reinstall mmcv-full

On the end give many errors but worked. And rembg extension gived error also so i removed. The others extensions worked fine and i'm using many extensions.

I get the below when i try pip install --upgrade --force-reinstall mmcv-full

raise EnvironmentError('CUDA_HOME environment variable is not set. ' OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.
