AttributeError : 'NoneType' object has no attribute 'parameters'

I wanna find the 'parameters' method in any model, but I couldn't. how can I fix that?

I found the problem.. I can't make model. if I run the main.py, they make model as 'None' type. what is my mistake??

I solved it. I use the MNIST dataset. but there is no condition for MNIST.
