Run NR tests on I420 pixel format frames / images

[pentanol2]

I am trying to run some NR metrics (musiq as an example) on images of pixel format I420. The frame size 1920x1080. I get this error shape '[-1, 3, 32, 32]' is invalid for input of size 3331072.

def proecss_frame(frame): 
   frame = TF.to_tensor(frame)
   frame = bt_frame.unsqueeze(0)
   return frame

What is the reason for this error? How can this be solved ?

Would you please provide example images and the metrics which give errors ? Thanks.
