I am getting this error after I run my test. This is beyond frusterating.

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.
To view examples of installing some common dependencies, click the
"Open Examples" button below.
It looks like you did not use pip to install sklearn. In the terminal you should run:
pip install scikit-learn
and make sure it runs without errors.

i have installed scikit-learn using pip command, however while trying to import module of sklearn in Jupiter notebook as well as in PYCHARM, i continuously get following error. I am working in python3.9. I am new to the interface, so it is requested to suggest solution for this issue.

It seems that scikit-learn has not been built correctly.
If you have installed scikit-learn from source, please do not forget
to build the package before using it: run python setup.py install or
make in the source directory.
If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform

As you can see in this bug report, the new sklearn version 0.24 crashes on MacOS<10.15 systems.
Until this bug is fixed, the developers suggest installing the previous version using pip install -U scikit-learn==0.23.

I recently used the pycharm on the same machine and downloaded the packages in it. From that moment onward I am getting the above mentioned error in my jupyter notebook.
Try installing scipy and restarting python shell
Upgrading scikit-learn worked for me:
$ pip install --upgrade scikit-learn
I installed pytorch using pip3 command for my windows pc without GPU support.
But when I tried to import torch it is giving an error.
At first, there was a different error saying numpy version not matching and I updated the numpy to the latest version.
import torch

I reinstalled anaconda and then created a virtual environment for pytorch.Now everything works fine
If you are running this in colab, remember to restart your runtime after installing your modules with pip.
I am on windows using Anaconda with python 3.6, I have installed keras by:
conda install -c conda-forge keras
and whene i try this code
from keras.models import Graph
I get this error message:
ImportError Traceback (most recent call last)
<ipython-input-4-74d2d1fd7bad> in <module>()
----> 1 from keras.models import Graph
ImportError: cannot import name 'Graph'
This is not a Python issue. This is because the latest version of keras has removed Graph module from models. You can surely check the documentation.
If you check this Github issue (Why Keras remove graph model?), you can use the following line of code:
from .legacy.models import Graph
However, it is suggested to use functional API instead. Please check The Functional API
I installed the Networkit module with conda install -c vgauthier networkit. If I import it in a notebook (import networkit as nk) I get this error:

Anyone able to explain why?
I happened to have the same problem for networkit via pip. It is because the networkit installed by anaconda does not link to your gcc compiler correctly, a simple fix is to download the networkit's source code and run python3 setup.py install to install it.
I had the same problem:
https://github.com/kit-parco/networkit/issues/172
It's because of anaconda Python. Re-install it using:
conda install -c vgauthier networkit
installing it with conda instead of pip solved the problem for me. See instructions here.
