# methods indicated in `example_args` before calling `torch.jit.script`.
# Otherwise the user would have to do this manually, which is tedious. This
# technically mutates the user input model which is not great but probably okay
# for this kind of API sugar. Users can always take full control of the process
# by scripting the model themselves before passing it to `torchscript.compile`.
