Hi @mikegerber, I've just made two commits to the 1.0 branch: the first is trying to fix the regex problem and the second to make all the tests run without warning. Could you please test if this works with ocrd_calamari?

Unfortunately this only got called for the default parameters, not the ones read from the model on disk. I've had another look and opened PR #349. That PR fixes the issue for me!
(I have 2 other issues with 1.0.x - more NumPy noise and another small issue with noise in the output. If you want to release another 1.0.x version maybe wait a little bit, I still need to investigate if it's Calamari or ocrd_calamari.)
Thanks a lot – I didn't have an old model so I was just guessing where to fix the regexes... If you have any other suggestions, I'll gladly include them in the 1.0.7 release!
Yeah I should have linked our historic model so you can reproduce :)
If you need a working model for 1.0 in the future: https://qurator-data.de/calamari-models/GT4HistOCR/2019-12-11T11_10+0100/model.tar.xz
(only for old prints/Fraktur)
If you have any other suggestions, I'll gladly include them in the 1.0.7 release!
I'll try to debug today!
The other issues:
UserWarning
from NumPy 1.26.1, but it's not a problem in Calamari.So I think you could release 1.0.7 when #350 is merged and this issue can be closed too :)
Nevermind, there's still lots of DeprecationWarnings I'd like to take a look first (other than the ones @andbue thankfully already fixed)
Sorry @mikegerber – I did not see #350 when releasing 1.0.7.
I'll merge that soon. So perhaps we should do another 1.0.8 ...
More than anything else we urgently need to backport the recently added support for TF SavedModel format to all the older branches – because HDF5 models stop working across the Python 3.8 / 3.9 boundary IIRC. The main problem with that is we cannot just increase the version tag of the older models retroactively (as was done with 5→6 in master). I have discussed this with @andbue and he is inclined to implement the auto-conversion without version update there.

done.
I suggest we keep this issue open to track progress with the SavedModel format conversion in 1.x (and the other older branches).
We have old 1.0.x models that wouldn't run using the Calamari 1.0.x branch on Python 3.11, as the
replacements
use regexen now considered invalid in Python 3.11:E.g. in our
0.ckpt.json
:The global
(?u)
regex flag needs to go in front. This script fixes it: https://github.com/OCR-D/ocrd_calamari/blob/master/ocrd_calamari/fix_calamari1_model.pyThe question is if you want this "upgrading" procedure to go into the 1.0 branch's modeling loading code?
(I haven't checked any other 1.0 models, but I am somewhat sure that these replacements weren't customized by us and came from Calamari itself.)
