[Error] Model save error when including lr_scheduler

[FacerAin]

Model save error when including lr_scheduler like this Can‘t pickle local object‘get_linear_schedule_with_warmup’\＜locals\＞ lr_lamda‘

You can solve this error to add dill library like this

import dill  
...  
torch.save(model, "model.pt", pickle_module=dill)
