Coco export start categories id from 0 instead of 1

[Binnette]

Coco format needs that categories ids start with 1.

Ex: if I have 3 categories, their ids should be 1, 2 and 3.

But sadly label-studio via "export coco", set them as 0, 1 and 2.

Ok I bypassed the issue by setting explicit categories id in "settings > labelling interface > code". Then add category="1", etc.

Note, during previous export I didn't set this, so the export started with category id 0. But still this is a bug, it should start by 1 to be conform with Coco norms.

See example :

<View>

  <Header value="Select label and click the image to start"/>
  <Image name="image" value="$image" zoom="true" zoomControl="true"/>
  <PolygonLabels name="label" toName="image" strokeWidth="3" pointSize="small" opacity="0.9">
    <Label category="1" value="top" background="#f66151"/>
    <Label category="2" value="destination" background="#dc8add"/>
  </PolygonLabels>

</View>

Hello,

Yes, if you set the category to what you want to start with. I'll create a bug ticket for it but please note that our team prioritizes bugs based on impact and how they align with our current roadmap, so we can't provide an exact timeline for a fix at this time. However, we’ll keep you updated as we make progress and will notify you once work begins and when the fix is delivered.
Thank you for your patience.

Thank you,
Abu

Hi Abu, thank for your answer. No problem, I found a workaround, so this bug can be fixed when the team have needed resources. Have a nice day.
