I want to import sklearn but there is no module apparently:

ModuleNotFoundError: No module named 'sklearn'

I am using Anaconda and Python 3.6.1; I have checked everywhere but still can't find answers.

When I use the command: conda install scikit-learn should this not just work? Where does anaconda install the package?

I was checking the frameworks in my python library and there was nothing about sklearn only numpy and scipy.

Please help, I am new to using python packages especially via anaconda.

You can just use pip for installing packages, even when you are using anaconda:

pip install -U scikit-learn scipy matplotlib

This should work for installing the package.

And for Python 3.x just use pip3:

pip3 install -U scikit-learn scipy matplotlib

Brief Introduction

When using Anaconda, one needs to be aware of the environment that one is working.

Then, in Anaconda Prompt one needs to use the following code:

conda $command -n $ENVIRONMENT_NAME $IDE/package/module

$command - Command that I intend to use (consult documentation for general commands)

$ENVIRONMENT NAME - The name of your environment (if one is working in the root, conda $command $IDE/package/module is enough)

$IDE/package/module - The name of the IDE or package or module


If one wants to install it in the root and one follows the requirements - (Python (>= 2.7 or >= 3.4), NumPy (>= 1.8.2), SciPy (>= 0.13.3).) - the following will solve the problem:

conda install scikit-learn

Let's say that one is working in the environment with the name ML.

Then the following will solve one's problem:

conda install -n ML scikit-learn

Note: If one need to install/update packages, the logic is the same as mentioned in the introduction. If you need more information on Anaconda Packages, check the documentation.

E ModuleNotFoundError: No module named 'requests' ______ ERROR collecting  ModuleNotFoundError: No module named 'flask'? Hi guys, ran the installer.bat and edited the start.bat files to point to the server location but it continues to refuse connection. No firewalls running during testing, and I've ran the commend Python via command prompt in the folder containing the server file.

I've tried a lot of things but finally, including uninstall with the automated tools. So, I've uninstalled manually scikit-learn.

sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/sklearn
sudo rm -R /home/ubuntu/.local/lib/python3.6/site-packages/scikit_learn-0.20.0-py3.6.egg-info

And re-install using pip

sudo pip3.6 install -U scikit-learn

Hope that can help someone else!

Trying to run your script, get this error: Traceback (most recent call last): File "./", line 18, in import git ModuleNotFoundError: No module named 'git'

This happened to me, I tried all the possible solutions with no luck!

Finaly I realized that the problem was with Jupyter notebook environment, not with sklearn!

I solved the problem by re-installing Jupyter at the same environment as sklearn

the command is: conda install -c anaconda ipython. Done...

Traps for the Unwary in Python's Import System, While Python 3.3+ is able to import the submodule without any problems: File "​<string>", line 1, in <module> ImportError: No module named ''. In my case, because I'm using PyCharm and PyCharm create a 'venv' for every project in project folder, but it is only a mini env of python. Although you have installed the libraries you need in Python, but in your custom project 'venv', it is not available. This is the real reason of 'ImportError: No module named xxxxxx' occurred in PyCharm.
