I am using Jupyter notebooks with some specific python libraries (AiiDA). My problem is that every time I run my notebook, the ipykernel_launcher process will take 100% cpu indefinitely, even after the calculation in the notebook has long finished. Here's a screenshot from htop

How could I debug what is causing this problem? Currently I have to just shut down the jupyter kernel after every time I run the notebook to avoid slowing down my computer.

  • It seem to me that you use linux then have a look at this https://stackoverflow.com/questions/386945/limiting-certain-processes-to-cpu-linux – Chris Golden Jun 08 '21 at 00:49
  • @ChrisGolden thanks for the comment. However, the `ipykernel_launcher` should not take any cpu when the jupyter notebook is idle! I am wondering if I can somehow figure out what is causing the cpu usage. – eimrek Jun 08 '21 at 09:53
