Error in _valid_image_format
I used the following command and got an error since insert
does not work for strings.
[ubz97wr@jean-zay1: ubz97wr]$ teklia-dan dataset extract --element-type single_page --parent-element-type single_page --train-folder 84cf52ed-cf83-44a3-aeaf-6047dc77ec91 --val-folder a3fcec0e-4551-40fd-a126-6f48e65cbdb4 --test-folder 5fe22c19-9d7f-44dd-a97b-35e9b6c524b8 --transcription-worker-version f13c4f76-e2d4-4083-9662-0fc4545989da --image-format jpg --max-width 1250 --max-height 2500 --output $SCRATCH/hennessy_letters/
