Got many error from "sklearn" Python library

Question

I run simple code in jupyter:

from sklearn.datasets import load_iris
iris = load_iris()

and I didn't use numpy library but I got this:

g:\program files\python37\lib\site-packages\sklearn\feature_extraction\image.py:167: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, 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.

It's not an errors, it's just warnings about some deprecated `sklearn` features — Ihor Konovalenko, Dec 07 '21 at 08:29
You should perform a `pip install -U scikit-learn numpy` as it seems that you are using old packages versions. — Antoine Dubuis, Dec 07 '21 at 08:45

It looks like your libraries are outdated, hence this deprecation warning.

I would advise you to update numpy and scikit-learn using the following command:

pip install -U scikit-learn numpy
