How to create a mask like DAVIS dataset?

[sevenlovechen]

I tried to apply the method to my own dataset.
But I am not sure how to create a mask for the first frame?
Is there any information?
Thanks

I have been using labelme to create masks for this RVOS repo

@sevenlovechen did you train the model on your own dataset?
because i failed to do so.
