The kernel error appearing on my anaconda juppyter notebook.
I have tried to change " shell:False" to "shell:True", but it didn't work.

actually the environment that you made then you must have deleted them , there were refrences for those envs ,
soultion : used this in cmd :
python -m ipykernel install --user

I'm having trouble running python code on juypter notebook. The following error message appears when I click on Kernel. Does anyone have a clue of what's wrong?
Thanks in advance!

Using this answer from another thread, I solved my issue.
I simply had to update jupyter notebook kernel using
pip3 install ipykernel --upgrade
python3 -m ipykernel install --user
Like many, I have reinstalled Anaconda after upgrading to MacOS Catalina. I did not 'uninstall' but deleted the folder (I am not a power user but an occasional user of python).
I did a clean install of Anaconda 3, and updated python to Python 3.8. When I start a notebook, I get the error message "Kernal Error."
Clicking on the "Kernal Error" button, I see the following message:

But when I type 'python' in the terminal, I see that python 3.8 is installed:
Can anyone help me understand this better? While I am at it, am I running the risk of confusion between this new anaconda installation and the initial one?
I just installed miniconda,jupyter notebook, python, and some packages.
I have the appropriate version of pywin32.

I got a similar issue yesterday. Try running this code in the CMD
conda install pywin32
and install it if you use Anaconda.

check out permissions to that folder inside users\DELL\

It was working good yesterday, but today I don't know why I get this error as I'm new to Python at all
Absolutely! Try conda uninstall jupyter notebook in the CLI and then install it again using conda install jupyter
