Ocropus 4.4. crashes on Xubuntu 10.4

I have problems with Ocropus 4.4. (open source OCR). I installed Ocropus and neccessary libries following this script. Compilation/Installation goes without any problem.

However after successful installation of ocropus, I am not able to run any of ocropus-* commands. Ocropus-page and ocropus-hocr crash without giving any error meaningful message. I just get a cryptic killed after 2 minutes of processing.

Killed

I do not know whe开发者_StackOverflow中文版re to start to fix it. Has anybody an idea where to start?

My machine is XUbuntu 10.4 64bits (run in VirtualBox) with 512MB of base memory.

I would try to convert your images to uncrompressed tiff before processing. I know that ocropus is working closely with tesseract and that tesseract handles 1bpp uncompressed tiffs the best.

Despite this being an old question I thought I'd post a solution / some debug tips as I experienced the same problem under the same scenario. The scenario being: Debian running under VirtualBox with 512MB RAM

In order to debug "Killed" messages you should look into /var/log for help. In my case kern.log contained:

debian kernel: [89675.791910] Out of memory: Kill process 13004 (ocropus-rtrain) score 806 or sacrifice child

debian kernel: [89675.791951] Killed process 13004 (ocropus-rtrain) total-vm:800816kB, anon-rss:412424kB, file-rss:4kB

It's likely you need to increase the amount of resources assigned to the VM particularly if you're running some big fancy window manager in the background!
