Spyder & IPython console: cannot connect to the kernel after updates #12960

Open paul18frr opened 2 years ago

paul18frr commented 2 years ago

Hi

I've asked this morning a full conda update using as usual: "conda update --all" .

Nonetheless when opening Spyder, I noticed in the console that it cannot connect to the kernel.

Note I'm under Windows 10 pro OS.

Hopefully I was able to move back to the previous revision using "conda install --revision n" (n=115 in my case); be patient - it takes some times

Here is the list of last revisions in my case:

Hope it helps

Please downgrade to jupyter-client 7.3.1 to fix that error.
