vsc 无法识别 sklearn

Question

I have scikit-learn installed and although it works fine in jupyter notebook, vsc keeps bringing up No module named 'sklearn' . I have uninstalled and reinstalled it and i have upgraded it, nothing works.

Installing collected packages: scikit-learn
Successfully installed scikit-learn-1.1.2

Answer 1

This is where your sklearn package is installed

Requirement already satisfied: scikit-learn in c:\users\manos\appdata\local\packages\pythonsoftwarefoundation.python.3.10_qbz5n2kfra8p0\localcache\local-packages\python310\site-packages (1.1.2)

This is your command to run the code

PS K:\portfolio_py> & "k:/portfolio_py/temporary app/virtual/Scripts/python.exe" k:/portfolio_py/titanic_random_forest.py

Obviously, your sklearn package is installed in the python310 environment. And you use the python interpreter in the virtual environment to run the code.

So the reason for the error is that the interpreter you are currently using is not the same interpreter that you installed the sklearn package with.

There are two solutions here

• Switch the currently used interpreter
  1. Ctrl + Shift + P
  2. Python: Select Interpreter
  3. Select the python310 interpreter with the sklearn package installed
• Install sklearn for the current virtual environment
  1. Select the interpreter in the virtual environment
  2. Create a new terminal to activate the virtual environment
  3. Install sklearn in the terminal
