"ModuleNotFoundError: No module named 'numpy.typing'"

I am trying to import ArrayLike doing from numpy.typing import ArrayLike, and I get the error mentioned in the title:

ModuleNotFoundError: No module named 'numpy.typing'

I know I could simply write import numpy.typing as npt as the documentation shows, but I would like the simplicity of just importing the types that I want to use. It is also not the first time that this has happened to me: I want to import a specific method/class but I'm forced to import the parent module with a nickname instead because otherwise, I get an Error. Why's that?

Solution

  • Re-posting the resolution in the comments above as a community wiki for better visibility:

    The numpy typing module was introduced in numpy 1.20

    Make sure that you have the correct numpy version by running the following at the beginning of your notebook:

    %pip install -U numpy
