I am training CNNs through transfer learning, following pytorch transfer learning tutorial. As shown below, after completion of training, type error occurs.
I shall be grateful, If anybody help me out.
Can you further show, how the function train_model() look like.
looks alright to me.
What are the last few printouts you get?
Please also share the return line of the function, maybe there is some issues?
I don’t know what the return hist would be.
The error is raised, since train_model doesn’t return anything, so you might want to add a return statement. This code snippet raises the same error:
def fun():
print("don't return anything")
fun() # works
a, b = fun() # fails
> TypeError: cannot unpack non-iterable NoneType object
