fra.traineddata corrupted ?

[japafrite]

Hey, this fra.traineddata (in tessdata_best) doesn't work, I get this error:
pytesseract.pytesseract.TesseractError: (1, "Tesseract Open Source OCR Engine v3.04.01 with Leptonica read_params_file: Can't open 1 read_params_file: Can't open -psm read_params_file: Can't open 7 Failed loading language 'fra' Tesseract couldn't load any languages! Could not initialize tesseract.")
And this file seems to small compared to others.
Everything works when I come back to original file.

Chances are high that you did not download the traineddata file, but an HTML page. Try to open the file in your editor.

My editor can't open it because it's not a text file or encoding is not supported.
Method applied : download button with firefox and then move file
fra.traineddata 4.0 on https://github.com/tesseract-ocr/tesseract/wiki/Data-Files => OK

Your tesseract (version) is old you download datafiles for recent version which of course does not work (expected behavior). Upgrade your tesseract and everything will works.
