How do I install transformers in Python?

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

Why causes the 'No module named transformers' error?

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