I tried switching to the kernel from Anaconda, but it also doesn't seem to work. Sometimes it just asks me to reinstall the ipykernel again. Thanks for your help.

Turns out I have a VPN, and it made it crash, i used this in the CMD:

netsh winsock reset

and it worked. Thanks for your help

CodePudding user response：

Use command pip install ipykernel in the cmd.

Alternative method:

Use following command in the terminal to reinstall pyzmq package.

pip uninstall pyzmq
pip install pyzmq
