How do I install scipy in Python?

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

Why causes the 'No module named scipy' error?

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