问题

I want to insert this code into my python:

import random
import warnings
import numpy as np
from sklearn.datasets import load_breast_cancer
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.linear_model import LogisticRegression
from sklearn.pipeline import make_pipeline

warnings.filterwarnings("ignore")

And the error is:

`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

I have installed numpy new as it looks like there is a problem as I understood with all these "int" within numpy.

but it doesn't resolve the problem; it is still the same problem.

Does anybody have an idea how I can resolve this problem? Or maybe somebody has experience with the same problem for Shapley value models.

Your `sklearn` and `numpy` versions are incompatible (see error message all the way at the bottom). A quick fix would be to downgrade `numpy` to `1.19.5`.
```cmd
pip install --force-reinstall numpy==1.19.5

Better would be to upgrade both packages as suggested in this question, as Python 3.8 is still actively supported.

pip install scikit-learn numpy --upgrade

pip install --force-reinstall numpy==1.19.5

pip install scikit-learn numpy --upgrade
