Cannot upload a simple dataset with two images

Hey i am unable to upload a folder containing the following files

  1. image1.tif
  2. image1.txt (containing labels of image 1 in yolo format)

3)image2.tif
4)image2.txt (containing labels of image 2 in yolo format)

5)data.yaml (contains the number of classes and names)

While i upload, a progress bar appears and vanishes with no comments/errors or notifications.
What am i doing wrong?

Sorry. I realized the mistake. I was trying to upload .tif images while it is not supported
I converted the tif images to .png images and i am able to upload now.
