Pronbelm while implementing the tiny YOLO v3 model

Hello guys,
I have been trying to implement the tiny YOLO v3 model and when I try to load the pre-trained weights into the model,I get this error.

File “/home/rahulrampa/.spyder2/”, line 274, in loadweights

RuntimeError: shape ‘[512, 256, 3, 3]’ is invalid for input of size 723278

Any ideas on how to fix this problem?
Thanks in advance

I am getting the same error. Did you find any solution?
