Possible to use torch::optim with LibTorch-Lite?

This may be a dumb question, but I’m in the process of converting some Python PyTorch code to run on mobile.

Are the following torch::optim classes (or equivalent functionality) supported in LibTorch-Lite?

optimizer = torch.optim.Adam(parameter_list, ...)
scheduler = torch.optim.lr_scheduler.LambdaLR(optimizer, lr_lambda=lambda ...

If not, would it be possible to build libtorch (not Lite) for running on mobile so I can use these classes?

I’ve searched around for similar questions but could find a solid answer to the above. Any help much appreciated.
