SE 3.5.13 & Tesseract 4.1.1 OCR Bug ( -1073741795 error ) #3933

Closed wtester7 closed 4 years ago

wtester7 commented 4 years ago

Hi @niksedk,

just tested your newly released SE 3.5.13 & Tesseract 4.1.1 but it is impossible to OCR a mks file. With SE 3.5.11 & Tesseract 4.1.0 there is no problem when OCR'ing...

Somethings wrong with Tesseract 4.1.1 in your SE 3.5.13. I have 7zipped the fresh portable SE 3.5.13 with the mks file "00003.mks" in the root directory so you can test the problem for yourself...

Btw, this happens with other mks files too!

Thanks Nik!

@stweil I have also tried the new OCR 5 Alpha from: https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w32-setup-v5.0.0-alpha.20200223.exe I have the same problem like @vivadavid

Tesseract_5_Alpha_Error

@wtester7 / @vivadavid : Could you try this new version and see if you still get the crash? https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w32-setup-v5.0.0-alpha.20200328.exe

Hi, @niksedk

I get a different kind of error:

Error: Tesseract (legacy) engine requested, but components are not present in C:\Program Files (x86)\Tesseract-OCR/tessdata/eng.traineddata!!

The file is certainly there, so the only problem I can think of is that Tesseract, in this alpha, can't access the subfolder because it's using '/' instead of '\'.

Is there a parameter I can use to tell Tesseract where the trained data is?

niksedk commented 4 years ago

Try this traineddata file: https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata Contains both legacy and new LSTM. Any better?

Also uploaded a new beta using latest version of Tesseract from Stefan: https://github.com/SubtitleEdit/subtitleedit/releases/download/3.5.14/SubtitleEditBeta.zip

Thank you, @niksedk

Now everything works. All 4 modes running directly Tesseract.exe and also running your beta of SE. I'm very happy! Thanks again!

niksedk commented 4 years ago

Thank @stweil :)

wtester7 commented 4 years ago

@niksedk and @stweil , yes the new version ( Tesseract 5.00 2020-03-28 Alpha ) is working well! Thank you for the fix!!

wtester7 commented 4 years ago

Btw, Tesseract 5.00 2020-03-28 Alpha is also much faster than 4.1.1, can't wait for 5.0 Final! Thank you again!!

Sorry, I forgot to thank you, @stweil

You are welcome. Thanks for reporting severe problems like this one. Best regards from @UB-Mannheim.

Wow. It really is very fast. And it's much better for Arabic.
