If you solve that problem, can teach me how to fix it? Thank you so much!!

There was another issue where someone pointed out this is happening on Windows but not on Linux machines. Are you using Windows for this?

I solved this by changing the signature of create_image_anno from,

def create_image_anno(objects, distractor_objects, img_file, anno_file, bg_file, w=WIDTH, h=HEIGHT, scale_augment=False, rotation_augment=False, blending_list=['none'], dontocclude=False):

to

def create_image_anno(objects, distractor_objects, img_file, anno_file, bg_file, w=WIDTH, h=HEIGHT, scale_augment=False, rotation_augment=False, blending_list=['none'], dontocclude=False, attempt=0):

It defines attempt before the function is called. I'm not sure why this works though.

@MC-devel-staudt after I doing this the objects are not being pasted on the background

Apparently all the object images need to be of the same size
