> 1: How can copy the layers from model\_x to create new model without issues?

[This answer](https://discuss.pytorch.org/t/how-can-i-replace-the-forward-method-of-a-predefined-torchvision-model-with-my-customized-forward-function/54224/8) here discusses in detail about how to create your own custom forward call using a pre-defined model.

[This post](https://discuss.pytorch.org/t/how-to-remove-the-intermediate-layers-of-model/85068/4) here discusses about removing intermediate layers from a model.

Hope these are helpful.
