How do I solve an import issue with numpy in scikit.decomposition.PCA?-CodePudding

I was trying to use the scikit.decomposition.PCA package and I couldn't even import it.

import numpy as np
from sklearn.decomposition import PCA

I've upgraded both of np and scikit, but the error seems to be w/in scikit, what should I do?

*Note: Using Python 3.8.5 in an .ipynb file on VSCode.

This is the error that shows up:

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

I tried to import PCA by using

from scikit.decomposition import PCA

but I keep getting the error that module 'numpy' no attribute 'float'

Note the numpy import works just fine.

CodePudding user response：

You probably have an incompatible version of numpy for sklearn. Try to downgrade numpy:

# Replace x by 0, 1, 2, 3, 4 or 5 (or use 'numpy<1.24.0')
[...]$ pip install 'numpy==1.23.x'
