Are HIP and OpenCL available?

It seems that the source code has not been implemented.

Yes, they're both supported. They use the common platform. See https://github.com/openmm/openmm-torch/blob/master/platforms/common/src/CommonTorchKernels.cpp.

The part that isn't currently implemented is executing the pytorch model with HIP. It uses CUDA if it's available and CPU if it isn't. If we could make it also use HIP, that would be good.
