Running cells with Python 3.10 requires ipykernel installed
Question:
I just installed Python 3.10 on my laptop (Ubuntu 20.04).
Running a Jupyter Notebook inside of VS Code works with Python 3.9 but not with Python 3.10. I get the error message: Running cells with 'Python 3.10.0 64 bit' requires ipykernel installed or requires an update.
Update February 2022
Jalil Nourmohammadi Khiarak gave a more complete answere, it is now the new accepted answer.
Update January 2022
It was a dumb error, I solved my problem (see accepted answer).
Things I tried:
- Clicking on reinstall, which runs:
/usr/bin/python3.10 /home/joris/.vscode/extensions/ms-python.python-2021.10.1365161279/pythonFiles/shell_exec.py /usr/bin/python3.10 -m pip install -U --force-reinstall ipykernel /tmp/tmp-12568krFMIDJVy4jp.log
- Running
pip3 install --upgrade ipykernel jupyter notebook pyzmq (from this thread).

- As asked in the comments, here is the output when I click the "reinstall" button:

I don’t think ipykernel is compatible with 3.10.
Below is the message I receive when I try to install ipykernel with the following command: conda install -c anaconda ipykernel
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- ipykernel -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.5,<3.6.0a0|>=3.9,<3.10.0a0']
Your python: python=3.10
Solution:
I recommend creating a virtual environment using conda or another library.
To get you started:
- Install Anaconda.
- Enter the following commands. [Note: These are the Windows commands – may vary slightly on Mac and Linux.]
# Create virtual environment
# Use a version of Python that is less than 3.10
conda create --name your_env_name python<3.10
# Activate new environment
conda activate your_env_name
# Install ipykernel
conda install -c anaconda ipykernel
# Add this new environment to your Jupyter Notebook kernel list
ipython kernel install --name your_env_name --user
# Windows only: When trying to launch `jupyter notebook`, you may receive a win32api error.
# The command below fixes that issue.
conda install -c anaconda pywin32
I finally found what went wrong. I am fairly experienced with Python coding, but still far from a pro when it comes to version handling in general.
The issue here is that ipykernel needs to be reinstalled for each new Python version you install. Therefore, what solved my problem is simply:
python3.10 -m pip install ipykernel
I would like to add a comment for that:
Your solution is correct but it didn’t work for me when I have used it on my new Linux. I did the following job to solve the problem.
Probably people after using the following comment:
python3.10 -m pip install ipykernel
Will get error for ‘distutils.util’. So you should install first:
sudo apt-get install python3.10-distutils
Then again if you try to install you will get the other error:
ImportError: cannot import name ‘html5lib’ from ‘pip._vendor’ (/usr/lib/python3/dist-packages/pip/_vendor/
To solve it you should use:
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
Finally, it would be best if you run:
/bin/python3.10 ~/.vscode/extensions/ms-python.python-2022.0.1786462952/pythonFiles/shell_exec.py /bin/python3.10 -m pip install -U notebook /tmp/tmp-5290PWIe78U4HgLu.log
MacOs M1
python -m pip install jupyter notebook -U
Use this and restart VSCode it works.
Also works if u see this error
Failed to start the Kernel.
The 'python3912jvsc74a57bd0f40663dfee16db09be6af2ff2550db36bd5354ec153147c40353828514dedb99' kernel is not available. Please pick another suitable kernel instead, or install that kernel.
View Jupyter log for further details.
It was working fine a few days ago but okay this solved it!
for windows not use terminal in your IDE
for conda env open anaconda prompomt then type
conda install -p "your python path" –update-deps –force-reinstall
