thank U sooo much.

And this operation is so slow, how to open multiprocess?

Thanks

stweil commented 5 years ago

It is slow, and there cannot be done much currently to get it faster. To be really fast, we would need a Tesseract with GPU support. The current CPU based training could be made faster by using float instead of double, but I am afraid that @noahmetzger does not have the time to implement that.

stweil commented 5 years ago

The crash is most probably a known problem. Run ulimit -c unlimited before running the training. Then Linux will create a core dump for the segmentation fault, and you can examine that to get more information.

Thank you so much.

@nathan-guo Is the problem solved?

stweil commented 5 years ago

The crash problem is still not solved, so it can occur.

@nathan-guo Is the problem solved?

The crash problem is still not solved

amitdo commented 3 years ago

We removed the training scripts from this repo.

What was the source of the crash? A bug in the bash script itself or in Tesseract C++ code. If it was the latter - do we have another open issue with the same bug?
