I have re-install the anaconda as well . but still It is showing the same kernel error.
Kernel json file shows :
{
"argv": [
"C:\\Users\\Khushboo.Girotra\\python.exe",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "Python 3",
"language": "python"
}
I have tried lot of solution which are already there but nothing works out . Kindly help
Hello,
I got through the same error today (this is really annoying, especially because it also breaks vscode interactive window and all my kernels).
After checking, pywin32 had a release 15 days ago for the first time in one year. Downgrading in my environment make jupyter work again (but it is obviously not a fix) :
pip install --upgrade pywin32==224Note that creating a new environment from scratch does not fix your problem :
pip install jupyterreinstallpywin32==225which is buggued and seems not to work on windows in its current state.Try
conda install pywin32if you are using conda.I’m referring to the setup.py that’s in the repository: https://github.com/jupyter/jupyter_client/blob/5.3.3/setup.py This file isn’t laid down during installation but it’s what is used during
jupyter_client’s installation.You might try
pip install --upgrade jupyter_client. You should havepywin32installed.This solved my problem.
pip install --upgrade pywin32==224 thank you very much,it work
I have installed anaconda , under that jupyter notebook also get installed . I have 5.3.3 version and pywin32 is installed . Still there is kernel error.
I was facing the same issue with
jupyter-client==5.3.4,jupyter_core==4.6.1, andpywin32==227. Runningpip install --upgrade pywin32==224 --force-reinstallthen fixed the issue for me.My system is Windows 64 bit. This solved for me.
conda install -c conda-forge pywin32 conda install -c anaconda jupyter_client conda install -c conda-forge jupyter_core
I encountered this problem too but I wasn’t using Anaconda. Turns out there’s another step (it’s in the pywin32 README):
Hope this helps someone!
Thank you so much!! this worked me!
OMG bro you save me! Thanks!
Thanks for the update. You’ll need to figure out why
import win32apiis not working. There are a number of SO hits on this issue, some of which state thatpip install pypiwin32resolved the issue. I don’t have access to a windows machine, so can’t really help much more than this - sorry.Runnig the postinstall from an elevated command prompt worked for me:
python Scripts/pywin32_postinstall.py -installPlease try relative to
pywin32. Since this is a conda env - you might be better off withconda install pywin32.@minrk updated the dependencies in conda-forge earlier today. These instructions might help get you going: https://github.com/conda-forge/jupyter_client-feedstock#installing-jupyter_client
Thanks big time Galileo-Galilei, downgrading pywin32 to 224 fixed the issue for me too. For my virtualenv, that is:
pipenv run pip install --upgrade pywin32==224And ye, pywin32==225 was released 15 Sep, pretty much the time I updated a load of modules + when Jupyter broke, so it all makes sense now.Same issue, fixed downgrading to pywin32==224. Thanks a lot!
@kevin-bates
If codes are not visible then you can use your desktop or laptop for better visualization. Here is commands that are used in the video…!! step 2 command :- “conda activate (location of your env folder)” step 3 command: - “python -m ipykernel install --user”
Thank you, solved to me too. my actual pywin32 ver is 227, downgrading solved the problem.
Regards

I’m new to anaconda and this is what my kernel error says could someone help me fix it i’ve tried all the solutions, uninstalled and installed, but none worked.
Closing issue based on recent successes.
Using the latest versions of jupyter_client (>=5.3.4) and jupyter_core (>=4.6.1) should be attempted prior to opening a new issue. Thank you.
Had same issue and upgrading jupyter_client worked.
pip3 install --upgrade jupyter_clientThanks a lot @Galileo-Galilei! This solved the issue for me too. As for the others, please note that if you have several conda virtual environments and you use them as a kernel in jupyter notebook. The process he mentioned needs to be repeated for each of them after activating them! So happy I got this working after 2 useless days
