Hi @glenn-jocher , I have experienced the same issue. It seems to be that README is wrong. They have this note: "for classes that are composed by different words please use the _ character instead of the space (only for the inline use of the argument --classes). Example: Polar_bear." But in fact df_classes object contains classes without underscore. So, I resolve it just deleting underscore while downloading (e.g. 'Polar bear' in classes.txt).
Best regards, Daniil

The toolkit woll delete the _ and replace it with a blank space
