problem with jupyter's recent update

Hi

I am using the latest jupyter-notebook version (5.3.0-4) in community repo, last updated on 2018-08-06 08:26 UTC.
Before the update everything was workking fine, however after update the Kernel keeps restarting repeatedly when I create a new file.

I got the following logs

[I 21:19:23.551 NotebookApp] KernelRestarter: restarting kernel (3/5), new random ports

Am I the only one with this problem? If so, could anybody please suggest workarounds?

Thanks.

Re: problem with jupyter's recent update

In my particular case, yesterday's updates also python from 3.6.3 to 3.7, amongst others, broke my virtual environments and couldn't start anything jupyter-related.

P.S.: It´s not only me https://bbs.archlinux.org/viewtopic.php?id=239356

Re: problem with jupyter's recent update

I've tested and pushed an updated ipykernel package.

If your problem is fixed, please edit your first post and prepend "[Solved]" to the thread title. smile
