# 安装依赖
从源码安装(推荐):
```
git clone https://github.com/modelscope/DiffSynth-Studio.git
cd DiffSynth-Studio
pip install -e .
```
从 pypi 安装(存在版本更新延迟,如需使用最新功能,请从源码安装)
```
pip install diffsynth
```
## GPU/NPU 支持
* NVIDIA GPU
按照以上方式安装即可。
* AMD GPU
需安装支持 ROCm 的 `torch` 包,以 ROCm 6.4(本文更新于 2025 年 12 月 15 日)、Linux 系统为例,请运行以下命令
```shell
pip install torch torchvision --index-url https://download.pytorch.org/whl/rocm6.4
```
* Ascend NPU
1. 通过官方文档安装[CANN](https://www.hiascend.com/document/detail/zh/canncommercial/83RC1/softwareinst/instg/instg_quick.html?Mode=PmIns&InstallType=local&OS=openEuler&Software=cannToolKit)
2. 从源码安装
```shell
git clone https://github.com/modelscope/DiffSynth-Studio.git
cd DiffSynth-Studio
# aarch64/ARM
pip install -e .[npu_aarch64]
# x86
pip install -e .[npu] --extra-index-url "https://download.pytorch.org/whl/cpu"
使用 Ascend NPU 时,请将 Python 代码中的 `"cuda"` 改为 `"npu"`,详见[NPU 支持](../Pipeline_Usage/GPU_support.md#ascend-npu)。
## 其他安装问题
如果在安装过程中遇到问题,可能是由上游依赖包导致的,请参考这些包的文档:
* [torch](https://pytorch.org/get-started/locally/)
* [Ascend/pytorch](https://github.com/Ascend/pytorch)
* [sentencepiece](https://github.com/google/sentencepiece)
* [cmake](https://cmake.org)
