UnknownArgumentError

[saumya750]

I am trying to test calamari with my calamari version being 2.2.2 and the below command:

calamari-predict --checkpoint D:\calamariOCR\calamari_models-2.0\calamari_models-2.0\antiqua_historical\2.ckpt --files C:\Users\Sam\Downloads\test_image4.jpg

I am getting below error: File "d:\pycharmprojects\calamariocr\virtualenv\lib\site-packages\paiargparse\main_parser.py", line 93, in parse_args raise UnknownArgumentError(f"Unknown Arguments {' '.join(argv)}. Possible alternatives:{''.join(help_str)}") paiargparse.dataclass_parser.UnknownArgumentError: Unknown Arguments --files C:\Users\Sam\Downloads\test_image4.jpg. Possible alternatives: --files ==> --voter, --data, --verbose

Please help.

Have a look at the docs: https://calamari-ocr.readthedocs.io/en/latest/doc.command-line-usage.html#example-usage The "--files" argument should be "--data.images".

I tried that too but that gives an error with the attribute 'int' in numpy event though my numpy version is 1.26.0 and this error should not occur for this version of numpy, correct? command: calamari-predict --checkpoint D:\PyCharmProjects\calamariOCR\calamari_models-2.0\calamari_models-2.0\antiqua_historical\2.ckpt --data.images C:\Users\Sam\Downloads\test_image4.jpg

To avoid this error in existing code, use int by itself. Doing this will not modify any behavior and is safe. When replacing np.i nt, you may wish to use e.g. np.int64 or np.int32 to specify the precision. If you wish to review your current use, check the release note link for additional information.

Is there some more context in the error message you get? I'm not sure where np.int is accessed from.

This is the entire error that I am getting and I have no idea why it is accessing np.int:

Thanks for reporting this! It seems that tfaip for some reason uses np.int. Until we fork tfaip and change it there, we need numpy version < 1.24.

Is there any requirement for open-cv version?Even On using numpy 1.21, I am still getting another error "numpy._DTypeMeta' object is not subscriptable":

I guess there are some version requirements between opencv-python-headless and numpy. Did you start with a clean venv or did you install some packages manually?
