Whatever is in your network volume isn’t just available on ur serverless for python packages
This is bc when the docker initializes, and it gets python it will set it’s python packages to be something like /somewhere/packages.
But not under runpod-volume/package.
Thus, what you should do is not worry about keeping this PIL in your network-volume instead for you docker file try to just pip install it during the build process instead of ur dockerfile that way it will just be automatically there.
Prob if you have something like a:
COPY requirements.txt .
In your dockerfile just add the pip install -r command to install stuff under it
