Thanks for checking out garage and metaworld!
At the moment, MAML doesn't support training on gpu, because it would actually cause training to be slower, than if you were to instead train it on CPU.
The MAML policy is so small in the number of weights that it can be trained with, that it wouldn't make sense to train it on a gpu.
I don't foresee that we will plan on adding gpu support for it, but if you would like to implement a .to method for it, check out SAC, to get a better understanding of how to. It's only 3 or 4 lines of code.
I'll do some experiments myself. Thank you for your reply.

Hi, everyone:
I want to train an example maml_trpo_metaworld_ml10.py(pytorch) on CUDA, so I added some codes:
from garage.torch import set_gpu_mode
if torch.cuda.is_available(): set_gpu_mode(True) else: set_gpu_mode(False) algo.to()
but it seems that the program cannot be trained on CUDA. Traceback: AttributerError: 'MAMLTRPO' object has no attribute 'to'. I've noticed that there are a lot of algorithms in garage have similar problems. How to resolve this problem, could you help? Thanks!
