kraken segment command hanging

[mittagessen]

I know some people used WSL successfully in the past but we officially don't support Windows and I don't have access to any machine with which I could verify if kraken works or doesn't work with Windows/WSL.

You could increase the verbosity with -v to get a bit more output and see where exactly in the process it hangs but the segmenter is a complex beast and blind remote-debugging is unlikely to lead to much.

Solved by upgrading to the newest release. I am running Ubuntu 22.03, so this was not a WIndows issue on my end.

Interesting. There's was a regression in 5.0 with segmentation but that caused crashes not hangs. Anyway, good to see it has been resolved.

I also get the same issue when importing kraken in a Python script. It just hangs. I tried from iPython, and importing kraken also hangs.

Did you find a solution?

Thanks everyone, upgrading to the latest version has solved my issue as well, so it wasn't a problem of WSL.

Yes seems in WSL it didn't give any visible crash.

One more question, unrelated, when running only segmentation in kraken is the only output a JSON file? Or is there a possibility to get a PageXML file? Or convert the resulting JSON to PageXML? Thanks!

You can run any serializer on segmentation output only as well: ``` $ kraken -a -i ... segment -bl $ kraken -x -i ... segment -bl ``` produces ALTO/PageXML respectively.

Thanks for your reply! However, both these commands give me the following error:
