Some of the “examples” which are part of the README do not work. They miss the required parameter files. Pls. add examples which actually work.

e.g. the pillow one should be gone.

ocrd_calamari is pushing for tf2 support.

When scrutinizing ocrd_anybaseocr this week, keep in mind to update if applicable.

Fixed by #59 for binarization already, this needs to be done for all processors. Moreover, this must be reflected in the documentation (ocrd-tool.json, README, docstrings) and tests.

In addition to or replacing the ocrd-tool.json fields or README, it might make sense to encourage proper python documentation with docstrings on modul level at least for the processors and use that information for the generation of documentation.

Please debug your ocrd_tool.json file.
I found an error:

<report valid="false">
  <error>NO ocrd-tool.json</error>
</report>

You can find the ocrd-tool.json documentation: https://ocr-d.github.io/ocrd_tool

Please check your README file and complet them. Your README is fine but look at your file and compare your's with the ideal README file.

Please debug your ocrd_tool.json file.
I found some errors:

I have never ever gotten a result from the official models at https://github.com/Calamari-OCR/calamari_models.

• Remove them from Makefile and README.
• Test them again
