Tensor size mismatch

Hi. I am receiving this error when I pass a .jpg input image of size (2160,4096,3) for testing. Can you please help me resolve this issue? Thank you!

Command I ran - python hybridnets_test.py -w weights/hybridnets.pth --source demo/image --output demo_result --imshow False --imwrite True

Traceback (most recent call last):
  File "hybridnets_test.py", line 121, in <module>

Hi @Gateway2745 , this is because the input size need to have the ratio 32x. 2160 : 32 = 67.5 not integer. So, you must resize your input (my suggestion is the input is 640,384).
