Issues in using kraken #54

Closed aayn closed 7 years ago

aayn commented 7 years ago

Hi,

I'm facing several issues while running kraken. I'm running Ubuntu 16.04 with python 2.7.12. One of them is, after succesful binarizing, segment throws a segmentation fault.

root@de2e05f9d21b:~/integrated-ocr/images# kraken -i test_image1.jpg image.jpg binarize
Binarizing      ✓
root@de2e05f9d21b:~/integrated-ocr/images# kraken -i image.jpg lines.txt segment
Segmenting      Segmentation fault (core dumped)

The other issue I face is this:

root@de2e05f9d21b:~/integrated-ocr/images# kraken -i test_image1.jpg image.txt binarize segment ocr
Usage: kraken ocr [OPTIONS]

Error: Invalid value for "-m" / "--model": Mappings must be in format script:model

Any clues as to why this is happening? Let me know. I'm even ready to help you in fixing it (if these issues are indeed reproducible).

I assume you're using the master branch because both errors are related to the script detection feature. The first is from a wrong clstm version, they changed the semantics of some fields. Try using the separate_derivs branch of clstm. Could you tell me which commit you where building from?

The second one is a regression and correct in the latest commit.

Spot on. Both issues are now fixed. Thanks :)
