I noticed yesterday that make all fails with Ubuntu 18.04 and any Python version, see CI protocol for a job based on this PR. The CI jobs hang and always print the same message until they get canceled:

parallel: Warning: Semaphore stuck for 30 seconds. Consider using --semaphoretimeout.

Newer Ubuntu versions don't show this issue. Is Ubuntu 18.04 still relevant, or should we remove it from CI now?

There seems to be a problem with that dinglehopper commit.

Also, CI failure on master looks like we have to hold numpy for ocrd_keraslm. Just pushed fix there 🤞

Wow, GH closes a PR if you force-push the only commit and does not allow reopening. Not sure whether this is new behavior but it certainly is annoying.

No, it is not and yes we should.

[kba]

Argh, my bad, I accidentally amended a commit that was in master m-(. Force-push and new PR incoming, sry about that.

ah, of course we are screwed there:

No, it is not and yes we should.

18.04 is still used in CircleCI. Does that need a change, too? I can prepare a PR for the rest.

And should Python 3.6 also be removed?

[bertsky]

ah, of course we are screwed there:

although py38 should still be covered by our nvidia-tensorflow workaround. Investigating...

Yeah, I was in the wrong branch, is now fixed.

Yes, but unless that is a breaking issue now, let's do it after this update.

And should Python 3.6 also be removed?

I'd say not right now, but in the next release?

So the pull requests #357 and #358 can included.
