Can't import MinMaxScaler "from sklearn.preprocessing import MinMaxScaler"

I run into the following error when running my script. Could someone please let me know what the issue could be? I have installed Sklearn on my system, and using "pip list" I can see 'sklearn 0.0" is present.

C:\Users\User\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pandas_datareader\compat\__init__.py:7: FutureWarning:

pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead.

ImportError: cannot import name '__check_build' from partially initialized module 'sklearn' (most likely due to a circular import) (C:\Users\User\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\sklearn\__init__.py)

Code:

import numpy as np
import pandas as pd
from sklearn.preprocessing import MinMaxScaler
Solution

  • So I found out what's causing this issue. some packages are not being installed due to file path length limit on windows. In order to fix this I had to: Type “regedit” in the Windows start menu to launch regedit.

    Go to the Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem key.

    Edit the value of the LongPathsEnabled property of that key and set it to 1.

    Reinstall scikit-learn (ignoring the previous broken installation): pip install --exists-action=i scikit-learn
