Segment command fails when trying to output as PageXML/ALTO #597

Closed fattynoparents closed 1 month ago

fattynoparents commented 2 months ago

When trying to use the segment command with output as PageXML/ALTO:

$ kraken -a -i ... segment -bl
$ kraken -x -i ... segment -bl

I get the error:

Version 5.2.4 gives me same error on Ubuntu 22.04 (WSL):

~$ kraken -x -i ~/images/test/79.jpg ~/images/test/79.xml segment -bl

Yes, I haven't tagged a new release with the fix yet.

I saw that you tagged the 5.2.5 release with my issue https://github.com/mittagessen/kraken/releases/tag/5.2.5 I'm now trying to run the code with a dev version 5.2.6.dev8 but get the following error:

kraken, version 5.2.6.dev8

That's not a kraken issue. You managed to install the pyarrow dependency with an incompatible libbrotlidec version. I'd purge the environment and try again.
