torch_musa is an extended Python package based on PyTorch. Developing torch_musa in a plug-in way allows torch_musa to be decoupled from PyTorch, which is convenient for code maintenance. Combined with PyTorch, users can take advantage of the strong power of Moore Threads graphics cards through torch_musa. In addition, torch_musa has two significant advantages:
- CUDA compatibility could be achieved in torch_musa, which greatly reduces the workload of adapting new operators.
- torch_musa API is consistent with PyTorch in format, which allows users accustomed to PyTorch to migrate smoothly to torch_musa.

NOTE: Since some of the dependent libraries are in beta and have not yet been officially released, we recommend using the development docker provided below to compile torch_musa. If you really want to compile torch_musa in your own environment, then please contact us for additional dependencies.

The following two key changes are required when using torch_musa:
-
Import torch_musa package
import torch import torch_musa
-
Change the device to musa
