Diagnostic checklist for “No module named ‘mpl_toolkits'”

• Verify pip install target. Run pip show mpl_toolkits — if not installed, run pip install mpl_toolkits.
• Check the active Python interpreter. which python (mac/Linux) or where python (Windows). Both pip and python must point to the same environment.
• Check virtual environment activation. If you use venv/conda, activate before installing: source .venv/bin/activate.
• Rule out uppercase/lowercase. Python imports are case-sensitive: import PyPDF2 not import pypdf2.
• Rule out the pip-vs-package-name mismatch. Some packages install under a different name than you import (e.g. pip install beautifulsoup4 → import bs4).

Installing mpl_toolkits

# Standard pip install
pip install mpl_toolkits

# In a virtual environment (recommended)
python -m venv .venv
source .venv/bin/activate  # or .venv\Scripts\activate on Windows
pip install mpl_toolkits

# With uv (faster alternative)
uv pip install mpl_toolkits

Common causes for “No module named ‘mpl_toolkits'”

• Python interpreter mismatch. Multiple Python installations can confuse pip. Verify with which python and which pip.
• Virtual environment not activated. If the venv isn’t activated, pip installs to your system Python instead.
• Notebook kernel mismatch. Jupyter uses a kernel that may differ from your terminal Python. Use %pip install mpl_toolkits inside the notebook.
• Import name differs from install name. pip install beautifulsoup4 → import bs4. Check the package’s PyPI page.
• Windows PATH issues. Ensure Python is on PATH; use python -m pip install to invoke pip via the correct Python.

Working code example

# Verify install worked
import mpl_toolkits
print(getattr(mpl_toolkits, '__version__', 'no version attribute'))

Best practices

• Always use a virtual environment. Avoids most module-not-found errors.
• Use pip freeze to lock versions. pip freeze > requirements.txt makes your setup reproducible.
• Consider uv or Poetry. Modern package managers with better dep resolution and reproducibility.
