Expected Ptr<cv::UMat> for argument 'contour'

[jbarth-ubhd]

Did build a new singularity image from docker ocrd/all:maximum today, approx. 14:00 CEST.

using this image (with OCR-D): https://digi.ub.uni-heidelberg.de/diglitData/v/duerer1527--aa--deskew.png

and using this command:
ocrd-eynollah-segment -P models default -I OCR-D-004 -O OCR-D-005 # ...004 contains png above

I'll get this error message:

Thanks for reporting! Possibly fixed now by @bertsky's #109 - we will make a new release asap.

Did build a new ocrd.sif from actual ocrd/all:maximum, still the same error:

I can confirm this is already fixed in main but there are other changes that broke the OCR-D CLI and are currently blocking this from integration in OCR-D. We will try to resolve and include these in a new release asap.

Problem is still there: https://digi.ub.uni-heidelberg.de/diglitData/v/christliche_kunstblaetter1862--40a--eynollah.zip (see run.sh for workflow & ocrd.log for log)

Problem is still there

Thanks and yes unfortunately - this is because OCR-D still uses an older version of Eynollah, which does not include the fix provided in 867a726.

We must first fix #106 before making a next release that is compatible with OCR-D again.
