cannot convert cvat xml to pascalvoc #236
Description
Hello,
i'm trying to export cvat xml to pascalvoc.
i'm letting cvat export the annotations to a gitrepo then i can do the following.
datum convert --overwrite -if cvat -i . -f voc_detection -o fooeg with the very trivial annotations in attach.
this gives me the following error
