module 'numpy' has no attribute 'ndarray'

Question

My Jupiter notebook was crushed, so I have to reinstall the notebook, but in the new Jupiter notebook, I cannot run pandas.

import pandas as pd

AttributeError                            Traceback (most recent call last)

     85 AnyArrayLike = Union[ArrayLike, "Index", "Series"]
     86 

AttributeError: module 'numpy' has no attribute 'ndarray'

I have tried to rename or delete the numpy.py, but it didn't work.

uninstall and reinstall numpy? pip uninstall -y numpy and then pip install numpy — garagnoth

The problem is not with Pandas. This is due to NumPy. I had a similar issue and this is what I did.

Ran python -c "import numpy as np; print(np.__file__); print(np.ndarray)". The expect output will contain the location of your installed NumPy package and <class 'numpy.ndarray'> for the second print statement. In my case, it seemed that NumPy package was located in ~/.local.

I tried reinstalling NumPy in conda, but the location was still the same. So, as per this solution, I deleted ~/.local. Then the error disappeared.

For me none of the above solutions fixed the issue. The only way it worked was I cleaned up all my python environments.

Removed manually installed python versions at various locations such as usr/local/bin
cleaned up PATH
Removed all but python 3.11 from brew.
Ran brew cleanup and resolved all warnings/issues.
Re-installed command line tools since I had been using the system installed python version for various projects.
Created a fresh virtual environment using brew's python3.11 as the base interpreter. Post this both numpy and pandas were not present and were installed fresh. No issues anymore.

If you're facing this issue on mac... I resolved it by installing numpy via Homebrew

brew install numpy

This fixed the issue for me.

In my case I had a script called numpy.py.
