How to save a complete model?

There are examples showing how to load the saved parameters of a model which is defined some place else.

How can I save an entire model in a single file and then load it later without a separate definition file? Is there a simple way to do this?

You could script/trace the model and export it. This wouldn’t need separate source files, but you would also be unable to manipulate the model easily.
I would not recommend to save the complete eager model via, as it would still need to import the source files while reloading and can break easily.

You can save model via but there are issues like pickling gpu-located models and if you decide to tinker with some functions or classes model is based on you’ll encounter that this is not possible.

Saving through model.state_dict() is a much more stable approach
