I wonder if I am the only one having the issue .... There are some files missing in the dataset
If you mean that some field IDs are not present in the label and field ID tifs, there was an issue with a few tiny fields not appearing. They have been removed (see discussion here: https://zindi.africa/competitions/iclr-workshop-challenge-2-radiant-earth-computer-vision-for-crop-recognition/discussions/717)
But if there are some files missing: did all the .tifs manage to download successfully? I once had a timeout which left me with some dates missing, but that was fixed by re-downloading through the radiant api. Which files are you missing?
I found out the issue was with my API that expired - It's working now
