Segmentation submit issue

Hi, I keep running into this problem when I submit. I've checked and every image I submit is different, and the format of the submitted data complies exactly with the requirements.

evalutils.exceptions.ValidationError: The images are not unique, please submit a unique image for each case.

The cause of this problem is unclear. However, based on other challenge feedback, it appears there were more than two files that contained zero masks.

Thank you for your reply. I checked and it seems that there are a couple of images predicted to come out as 0 masks, which should be a sign that my model is not predictive enough. So in this case the results can't be uploaded?

You can't upload them on the site right now. During the test phase, we'll be processing results locally, so you can submit those predictions then
