VS Code: ModuleNotFoundError: No module named 'sklearn'

Question

I am working in VS Code to run a Python script in conda environment named myenv where sklearn is already installed. However when I import it and run the script I get the following error:

Traceback (most recent call last):
  File "d:\ML\Project\src\train.py", line 5, in <module>
    from sklearn.linear_models import LinearRegression
ModuleNotFoundError: No module named 'sklearn'

I have tried all possible solutions suggested in the following but nothing worked for me:

• ModuleNotFoundError: No module named 'sklearn'
• ModuleNotFoundError: No module named 'sklearn.__check_build._check_build'?
• ImportError in importing from sklearn: cannot import name check_build
• importError: cannot import name __check_build #8754

Can someone suggest a different way to fix this?

Answer 1

according to pypi:

use pip install scikit-learn rather than pip install sklearn

in my experience this works:

C:\Users\gfernandez>pip install sklearn

Answer 2

Have you tried https://code.visualstudio.com/docs/python/environments

Had the same issue and solved it by setting vscode to use my conda environment.

Answer 3

I had the same issue using python 3.11.4, and installing scikit-learn by pip install sklearn. My solution was to use pip install scikit-learn, as shown in the following sequence:

Checking the scikit-learn version in PowerShell:

PS C:\Users\Administrador> python
Python 3.11.4 (tags/v3.11.4:d2340ef, Jun  7 2023, 05:45:37) [MSC v.1934 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sklearn
>>> print(sklearn.__version__)
1.3.0

Checking via cli the scikit-learn version in a VSCode environment:

Answer 4

I had a similar issue and after applying all recommended solutions, the problem persisted until I later discovered my VS-Code Python Interpreter was pointing to a different virtual environment.

I changed it to the working virtual environment and everything worked perfectly well.

Answer 5

I had a similar issue, I tried every possible solution for this, re-installing the package, double checking the python interpreter / kernel, check python and package version, making sure they had similar environments etc. Every time it gave the same error even when the requirement was already satisfied. Eventually this command helped me:

py -m pip install scikit-learn

Answer 6

I also have the same problem, but when I tried this command the error got fixed:

pip install sklearn

Answer 7

Click on the terminal in the VS Code and run the following command to create the virtual environment in VS Code.

python -m venv path location of the working file\myvenv

in VS Code it will automatically activate.
