cannot import sklearn in python jupyter notebook

Question

I have installed sklearn in anaconda prompt by pip install scikit-learn and showing successful

(base) C:\Users\user>pip install scikit-learn
Requirement already satisfied: scikit-learn in c:\users\user\anaconda3\lib\site-packages (1.0.2)
Requirement already satisfied: threadpoolctl>=2.0.0 in c:\users\user\anaconda3\lib\site-packages (from scikit-learn) (3.1.0)
Requirement already satisfied: scipy>=1.1.0 in c:\users\user\anaconda3\lib\site-packages (from scikit-learn) (1.7.3)
Requirement already satisfied: numpy>=1.14.6 in c:\users\user\anaconda3\lib\site-packages (from scikit-learn) (1.21.5)
Requirement already satisfied: joblib>=0.11 in c:\users\user\anaconda3\lib\site-packages (from scikit-learn) (1.1.0)

However , When I try to import sklearn with below code, it output errors.

# Import Libraries needed to load the data 
import pandas as pd 
from sklearn.linear_model import LinearRegression

I have tried below amendment but problems still. Hope someone can help.

$> conda remove --force numpy, scipy
$> pip install numpy, scipy

I don't use `conda` but it seems mixing `pip install` and `conda install` is full of issues. Perhaps try `conda install scikit-learn`? Also, is `base` a virtual environment? If so, you'll need to ensure that `jupyter` is using the same virtual environment where you installed `scikit-learn`. — rickhg12hs, Apr 03 '22 at 00:33

Create a cell in the notebook with the following content

%pip install scikit-learn

and execute it.

@QuinSinclair, please use current best practices when advising folks. To avoid the issues caused by environments in the shell and notebook perhaps being different, it is now modern best practices to use `%pip install` or `%conda install`, see [here](https://discourse.jupyter.org/t/why-users-can-install-modules-from-pip-but-not-from-conda/10722/4?u=fomightez). These magics commands were added recently to help mitigate environment problems. In fact, because of automagics usually being on by default, even no symbol in front of `pip` or `conda` will often trigger the correct magic command. – Wayne Apr 01 '22 at 16:08

I'm seeing in your list of errors the following:

from scipy.spatial.distance import cdist

This makes me wonder if you installed scipy, similar to what is suggested here and here, if that would help?

You can try in a cell in your notebook:

%pip install scipy

If it says it is already installed, maybe change it to read uninstall and then try the install of scipy again and then try your from sklearn.linear_model import LinearRegression line again.
