TypeError: cannot unpack non-iterable NoneType object

[Orchoidizer]

This is the error nessage I get when trying to replace the 'iron_man and multi people video' files with alternative files of my own to attempt my first video head swap.

TypeError Traceback (most recent call last)

in () 24 # img_a = Image.open(pic_a).convert('RGB') 25 img_a_whole = cv2.imread(pic_a) ---> 26 img_a_align_crop, _ = app.get(img_a_whole,crop_size) 27 img_a_align_crop_pil = Image.fromarray(cv2.cvtColor(img_a_align_crop[0],cv2.COLOR_BGR2RGB)) 28 img_a = transformer_Arcface(img_a_align_crop_pil)

TypeError: cannot unpack non-iterable NoneType object

Would anyone be able to throw any light on what I might be doing wrong?

Thanks
