## 从PyPI上安装
|
|
|
|
|
|
|
|
|
|
|
|
你可以PyPI上使用以下命令直接安装Colossal-AI。
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
pip install colossalai
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
如果你想同时安装PyTorch扩展的话，可以添加`CUDA_EXT=1`。如果不添加的话，PyTorch扩展会在运行时自动安装。
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
CUDA_EXT=1 pip install colossalai
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
git clone https://github.com/hpcaitech/ColossalAI.git
|
|
|
|
|
|
cd ColossalAI
|
|
|
|
|
|
|
|
|
|
|
|
# install dependency
|
|
|
|
|
|
pip install -r requirements/requirements.txt
|
|
|
|
|
|
|
|
|
|
|
|
# install colossalai
|
|
|
|
|
|
pip install .
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
如果您不想安装和启用 CUDA 内核融合（使用融合优化器时强制安装）：
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
|
NO_CUDA_EXT=1 pip install .
|
|
|
|
|
|
```
|
