Got exception using ocrd_detectron 2 with ocrd_all Release v2022-12-01

[stefanCCS]

I have got an exception using ocrd-detectron2-segment as follows - please clarify (I can provide workspace, if needed):

[bertsky]

Can you please show the contents of your model file /home/ocrdadmin/.local/share/ocrd-resources/ocrd-detectron2-segment/DocBank_X101.yaml, and describe how you got (downloaded) it?

[stefanCCS]

It is a VERY BIG file:

(ocrd-3.7) ocrdadmin@ocrd-03:/mnt/OCRD/myData/Specials/Detectron2Test$ ll /home/ocrdadmin/.local/share/ocrd-resources/ocrd-detectron2-segment/DocBank_X101.yaml

And, I have not downloaded in advance (I have thought, that this is done automatically, when I use -p).

--> So, maybe I should do ?

ocrd resmgr download ocrd-detectron2-segment DocBank_X101.yaml
ocrd resmgr download ocrd-detectron2-segment DocBank_X101.pth

And, now it see the output of ocrd-detectron2-segment -L is a bit strange (I only would expect JSON files, but I can see also pth/yaml files ?!):

And, I have not downloaded in advance (I have thought, that this is done automatically, when I use -p).

No, we have a PR for that OCR-D/core#799 but it got delayed because it is difficult to test.

To me it looks like the data got corrupted during download.

Try

ocrd resmgr download --overwrite ocrd-detectron2-segment DocBank_X101.yaml

[bertsky]

And, now it see the output of ocrd-detectron2-segment -L is a bit strange

No, that one seems correct.

I also believe some earlier download attempt must have been corrupted.

[stefanCCS]

Has not helped - still VERY BIG file.
I assume this in depending of this zip-Source-File.

[kba]

Has not helped - still VERY BIG file.

That is to be expected, it's a ZIP file containing a huge neural network (model itself is 797 MiB).

But does it work now with the processor, i.e. has the bitflip been corrected by redownloading?

[stefanCCS]

Sorry, forgot to mention: I still get the same Exception:

[stefanCCS]

Now, I have used ocrd-detectron2-segement with resources which are NOT in Zip-File.
And, I have got a different exception:

This is still strange for me, as I would expect to get the unzipped-yaml file (which should a be very small text file)

indeed, it should. Trying to reproduce with most recent version of ocrd_detectron2 (or did you say most recent version of ocrd_all?)...

I can confirm the extraction of the zip-file does not work with resmgr in core v2.43. There's the correct path_in_archive setting, but nothing gets extracted, the file just gets renamed. @kba perhaps my assumption that non-empty path_in_archive would imply type=archive does not hold?
