Error on segmenting image (shapely-1.8.5) #575

Closed johnlockejrr closed 7 months ago

johnlockejrr commented 8 months ago

I try to segment an image under eScriptorium but I get this error and all is messed up

So I tried under latest kraken 4.3.10

Found on an old issue that shapely-1.7.1 would work so I downgraded and tried with success but it seems is not compatible with latest kraken

What to do next?

mittagessen commented 8 months ago

Shapely 1.8.5 is the only version that works with kraken. That's why is it pinned.

Lines that fail the polygonizer are usually erroneous detections from the segmentation net. Ignoring the warning should be safe.

By the way, is there a kraken discussion platform somewhere? Gitlab or anyhing? Thanks!

Sorry, not related, is there a kraken 4.3.13 version? I saw that in eScriptorium requirements.txt dev on github "kraken~=4.3.13"? Thanks!

Yes, there's a 4.3.13 that should be both on conda and pypi.

Thanks, I didn't see it in /releases so I thought is a typo on their side
