When I imported an existing segmentation dataset from my computer to my Roboflow project I noticed that the WEBP images did not have annotations while the other images did. I had to convert the WEBP images in the dataset to JPGs for it to import successfully.
.webp is listed as a supported file format on the roboflow dashboard.
I’m guessing this a bug to do with how roboflow finds the annotations on the backend. Typically the way it works is for each image is there is a corresponding label .txt file given the same base name. I think roboflow is just replacing the ‘.png’ or ‘.jpg’ with ‘.txt’ to obtain the name of the label file. To fix this issue its probably a matter of just adding a case to check if the file is a ‘.webp’
