Hello, I am new in Pytorch and this question makes me waste a couple of days. I am trying to connect two different neural networks together. The model one is a trained NN which I have already saved as a .pth file. Then I want to put another NN with a totally different architecture after it. Then I combining those two models and train them together. How can I connect two models? I mean simply use the output from module one as the input of model two but use one optimize function to train them. Because I may put a dozen of models after them.
