I am trying to implement changing image size during training in my own implementation(i.e not by fastai lib). But whenever I change the size it gives error of size mismatch.
I want to know how @jeremy implemented this functionality in the fast.ai library .
Thing I want to accomplish.
I want to train the same model with different batch sizes i.e (224X224), (150X150), (100,100), (64,64).
How can I do it for my implementation?
