I created a python script in linux that uses tesseract and when running it everything works out and the output is correct when trying to run it on my windows computer tesseract is not identifying the numbers as numbers but instead as words attached is the same .png im using on both windows and linux as well as the corresponding outputs.
I understand that they are different version if that's the problem how do I download the newest versions for w10? as the newest download for windows is the one that I have (https://github.com/tesseract-ocr/tesseract/wiki/4.0-with-LSTM#400-alpha-for-windows).

version info for linux:
$ tesseract -v
tesseract 4.0.0-beta.1
 leptonica-1.76.0
  libjpeg 8 (libjpeg-turbo 1.5.2) : libpng 1.6.34 : libtiff 4.0.9 : zlib 1.2.11
 Found AVX2
 Found AVX
 Found SSE

version info for w10:
tesseract -v
tesseract 4.00.00alpha
 leptonica-1.74.1
  libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.5.0) : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0

See https://github.com/UB-Mannheim/tesseract/wiki for latest windows installers
See https://github.com/tesseract-ocr/tesseract/wiki#tesseract-4-packages-with-lstm-engine-and-related-traineddata for latest linux installers

The difference you see could also be because of different version of traineddata file you are using - try with the ones from tessdata_best repo

After making sure everything was updated I tried to use the eng.traineddata and now I'm getting the following assertion


lstm_recognizer_->DeSerialize(&fp):Error:Assert failed:in file ../../../../ccmain/tessedit.cpp, line 193

How did you get the traineddata? you need to usethe `raw` link.

wget -O eng.traineddata https://github.com/tesseract-ocr/tessdata_best/raw/master/eng.traineddata

If problem is with the new windows version, please file issue at https://github.com/UB-Mannheim/tesseract/issues as the maintainers might not be checking this forum often.

The assertion which you get was removed in commit dc8745e6fd4c6c070076c44565924faa0d0643a7 two years ago, so you are using an outdated version of Tesseract which is no longer supported.

Use `tesseract --version` to see the version of your installed Tesseract.

SOLVED
I solved it by downloading the 32 bit setup, it also fixed the bad recognition on windows vs linux without swithcing the train data
