Jupyter Notebook Kernel busy all the time

问题

I have instaled anaconda and python works fine in Sypder , IPython etc . However I am not able to run python notebook.

Kernel gets created , it also connects but it shows the dark circle busy symbol throughout . There is no problem with the firewall or antivirus . I have tried by disabling both .

I am also not able to open python terminal from notebook there is some powershell error.

Can anyone suggest something ?

Edit 1 : Added the snapshot and the log

Log Anaconda Prompt :

And the image where kernel is always busy

I was also getting the same issue, I tried a lot of different stuff but nothing seemed to help me out. Ultimately, a Kernel Restart instead of Kernel Interrupt helped me out! The kernel restarted and I was able to run the kernels as usual.

I think this is just a workaround if someone finds the real solution please do let us know!

I has the same issue because I started it as below

jupyter notebook --gateway-url=http://my-domain.com:8888

but I remove geteway-url param then the issue was gone

I know that you didn't make this very same mistake like me but I hope this gives you some clues
