How do I install yaml in Python?

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

Why causes the 'No module named yaml' error?

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