fcos for geospatial

[rdfong]

Hello, I'm trying to your FCOS implementaitn on my own geospatial dataset (I guess it's similar to the spacenet dataset) to detect buildings. I've followed your instructions for setting up the training and evaluation datasets, but I get no output, (the loss seems to go down but i'm guessing it's converging on predicting nothing).

Just to confirm a few silly things. Your xmin, xmax, ymin, ymax are defined in the standard format right? So left, right, top, bottom.

The typical image i'm training on looks like this:

Do you have any ideas of what parameters I might need to adjust to get good output?

Thanks a lot!
