## GPU/NPU Support

* **NVIDIA GPU**

Install as described above.

* **AMD GPU**

You need to install the `torch` package with ROCm support. Taking ROCm 6.4 (as of the article update date: December 15, 2025) on Linux as an example, run the following command:

```shell
pip install torch torchvision --index-url https://download.pytorch.org/whl/rocm6.4

* **Ascend NPU**

Ascend NPU support is provided via the `torch-npu` package. Taking version `2.1.0.post17` (as of the article update date: December 15, 2025) as an example, run the following command:

```shell
pip install torch-npu==2.1.0.post17
```
