Traineddata path issue on Windows 10. #14

Open gety9 opened 2 years ago

gety9 commented 2 years ago

When i run

python -m table_ocr.demo https://raw.githubusercontent.com/eihli/image-table-ocr/master/resources/test_data/simple.png

i get

pytesseract.pytesseract.TesseractError: (1, 'Error opening data file C:UsersGetyAppDataLocalProgramsPythonPython38libsite-packagestable_ocrtessdata/table-ocr.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language \'table-ocr\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')

(note file path does not have '/')

File does exist

I tried setting env variable TESSDATA_PREFIX - same error.

as well as specifying path in cli python -m table_ocr.demo https://raw.githubusercontent.com/eihli/image-table-ocr/master/resources/test_data/simple.png --tessdata-dir C:\Users\Btycoon\AppData\Local\Programs\Python\Python38\Lib\site-packages\table_ocr\tessdata

I am on Windows 10.

Sorry to say that I have very little knowledge of Windows 10. I'll leave this comment open for a while in case anyone else has a suggestion.

I'd write my workaround.

https://github.com/eihli/image-table-ocr/blob/49205462a3fb68240fd6a3d441ae7cf979b43daa/table_ocr/ocr_image/__init__.py#L30

Replace all backslash to forward slashes. tessdata_dir.replace("\\", "/").

After making the necessary changes, the program works. Windows 10, Python 3.10.4.

Also I found out that the built-in Tesseract data that my installation has is more superior compared to the shipped one, so I removed the related line entirely.

Replace all backslash to forward slashes. tessdata_dir.replace("\", "/").

Thank you, I was trying to find a problem all day

If anyone wants to submit a patch to make this more portable across Linux/Windows, please do!

How do I run this project after I make changes? I am new to this. So can you please guide on how to run this project? Thanks
