Problem with ocropus-recognize-book

[Angelica]

Hi,

When I'm trying to run the ocropus-recognixe-book command I get an AssertionError and I can't figure out why. OCRopus works fine when I'm running run_tests. I also looked at the run_test file and tried to do each stepa manually, but it doesn't work, it fails when I'm running ocropus-gpageseg. I tried some different images (including one of OCRopus' images) but same thing happens om each of the images.

This is the error output I get:

writing lines

Traceback (most recent call last):

  File "/usr/local/bin/ocropus-gpageseg", line 331, in <module>

    process1((f,i+1))

  File "/usr/local/bin/ocropus-gpageseg", line 307, in process1

    ocrolib.write_page_segmentation("%s.pseg.png"%outputdir,segmentation)

    raise e

    run(args.pageseg,book+"/????.bin.png")

  File "/usr/local/bin/ocropus-recognize-book", line 57, in run

    assert subprocess.call(args)==0

AssertionError

Does anyone know what the problem is, and how I can get it to work?

I think that probably means that there were no pages at all in the input. We got rid of the ocropus-recognize-book command in 0.7 because it's a lot of work to have it give good error messages. Just run ocropus-nlbin, ocropus-gpageseg, and ocropus-rpred individually, and it will generally be clear where the error is.
