This PR adds a new command line flag
--devicethat allows users to specify the device (e.g.cuda,cpu, ormps) to use for inference. The flag defaults tocudabut will automatically fall back tocpuif CUDA is not available. This change also updates the code to use the specified device for loading models and running the pipeline.torch.manual_seedsets the seed for generating random numbers on all devices. I removed the redundant call totorch.cuda.manual_seed.This code was generated while working on pytorch/pytorch#141471. Note that LTX-Video does not currently work when using MPS as the backend in latest PyTorch. This is a regression as it worked in PyTorch v2.4.1. Please follow pytorch/pytorch#141471 if you'd like updates on progress towards a fix.
