This is because when we run a loop until it s termination the Kernel is in busy state and so IN     is shown up  Since Kernel is busy and if we just leave that cell to execute completely and switch to another cell to run  the corresponding cell will get busy and so again for that cell IN    is shown  In that case you just need to restart your jupyter notebook and all is fine then    But be sure that your loop will terminate this time or else again this error will turn up

This means that Jupyter is still running the kernel  It is possible that you are running an infinite loop within the kernel and that is why it can t complete the execution    Try manually stopping the kernel by pressing the stop button at the top  If that doesn t work  interrupt it and restart it by going to the  Kernel  menu  This should disconnect it    Otherwise  I would recommend closing and reopening the notebook  The problem may also be with your code

The answers that state that your kernel is still executing the code in the cell are correct  You can see that by the small circle in the top right  If it is filled with a black grey color  then it means it is still running   I just want to add that I experienced a problem in JupyterHub where the code in the cell would just not execute  I stopped and restarted the kernel  shutdown and reloaded the notebook  but it still did not run   What worked for me was literally copy pasting the same code to a new cell and deleting the old one  It then ran from the new cell

updating ipykernel did it for me  it seems arch linux s ipykernel package had been outdated for some time  just do pip install --upgrade ipykernel  reference here  github solution

I have uninstalled jupyter  notebook and ipython  and installed jupyterlab  It is working for now  with just a few libraries installed and Python 3 6 8      Something to discard  Uninstalling Python 3 7 completely with his libraries and reverting to 3 6 doesn t fix it  although it improves it  it works intermittently now  but once sth doesn t work properly  things start to get worse and worse  so I did the above

Usually  stopping and restarting that particular cell fixes this issue

User · Answer

What I did was to quit the Notebook  and I started all over again  That is the proper solution  Restarting the Kernel really did not really help  But quitting did so try quitting and start again

I had the same problem  and the little star means that the kernel is still working  So the program is trapped in an endless while loop  So you only have to the rewrite the code

I had the same issue  I found that ipython must be running for jupyter notebook to execute  Do the following    Go to the folder where you have your ipython notebook  ipynb  Press shift and right click on the empty space then select  open command window here   This will open a command prompt window  Type ipython  This will start ipython  Open another command prompt window and open jupyter notebook  Open your file again and go to cell   run cell    This should work  It worked for me  Cheers

Based on you kernel status  upper right beside  Python 3   the one that is a circle   It seems that it is still busy  It might be trapped in an endless loop or maybe you ve run display something that is not closed

User · Answer

From my experience  it usually means one of the prior cells is keeping the kernel busy  When you hit run on the intended cell and     appears  from there  try to scroll up to the prior cell which is also advertising a      Then goto kernel- interrupt  and lastly  try running the cell again

If you have ad block installed in your browser  just switch it off and then stop the kernel and start again  now the code will execute
