Training with partially empty segmentation masks

[sabine1993]

Hi everyone,
does any one know if there is a possibility to train yolact with partly empty segmentation masks?
I don't have a mask for specific classes but I want to train one model.
I tried using segmentation=[] but I am running into an error during training.

Has anyone solved this problem or has an idea how to solve it?

I just encountered this issue. Any solutions yet?

I think it is necessary to train YolAct with segmentation masks. So I used Labelme to relabel my dataset and then I can train my dataset.

See the below to use Labelme:
