How can I get stub files for `matplotlib`, `numpy`, `scipy`, `pandas`, etc.?

2024/11/20 13:43:41

I know that the stub files for built-in Python library for type checking and static analysis come with mypy or PyCharm installation. How can I get stub files for matplotlib, numpy, scipy, pandas, etc.?

Answer

Type stubs are sometimes packaged directly with the library. Otherwise there can be some external libraries to provide them.

Numpy

Starting with numpy 1.20 type stubs will be included in numpy. See this changelog and this PR adding them

Before that they could added with the library https://github.com/numpy/numpy-stubs

Pandas and Matplotlib

There is no official support for these libraries stubs but you can find unofficial stubs in this project: https://pypi.org/project/data-science-types/

You can either install this library as a dependency or copy only the relevant part in the type stubs folder of your project.
