Yesterday my kernel died while I was checking the output of a statement and it’s still in the same state. When it happened I had been coding for at least 4 hours and I haven’t downloaded any apps or changed anything inside the system that could interfere with it. I’ve been using it for a year now and this is the first time this has happened.
The following notice appears when I try to restart the kernel:
The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.
When I attempt to run:
The kernel appears to have died. It will restart automatically.
Things I’ve done:
- Restarted, reconnected, shut down the kernel
- Opening it as admin
- Uninstalled it, deleted all the files related to anaconda and installed it again (cleaned the cache and used Clean My Mac X to get rid of all the files)
- Installed by adding it to a specific file under my admin account (Applications in Mac)
- Shut down & Restarted the computer
- Run conda update --all
- Uninstalling ipykernel, ipython, jupyter_client, jupyter_core, traitlets, ipython_genutils and then install again.
- Run conda update ipykernel
I also raun the following:
conda remove ipykernel ipython jupyter_client jupyter_core traitlets ipython_genutils conda clean -tipsy conda install ipykernel ipython jupyter_client jupyter_core traitlets ipython_genutils jupyter notebook
Nothing has worked so far
My terminal displays the following:
