How do I install PIL in Python?

The standard way to install PIL is by running `python -m pip install pillow`. If you are using Anaconda, use `conda install -c conda-forge pillow`.

Why causes the 'No module named PIL' error?

This error occurs when the python interpreter cannot locate the `PIL` package. It is often caused by missing installation or environment mismatch (e.g. installing in global but running in venv).
