## 模型下载(离线部署)
|
||||||
|
|
||||||
|
Wan2.2-TI2V-5B 是 HuggingFace 模型,需要先下载再部署。
|
||||||
|
|
||||||
|
### 方法1: huggingface-cli(推荐)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 安装 huggingface-cli
|
||||||
|
pip install huggingface_hub
|
||||||
|
|
||||||
|
# 下载模型到指定目录
|
||||||
|
huggingface-cli download Wan-AI/Wan2.2-TI2V-5B \
|
||||||
|
--local-dir /data/ymq/models/Wan-AI/Wan2.2-TI2V-5B \
|
||||||
|
--local-dir-use-symlinks False
|
||||||
|
```
|
||||||
|
|
||||||
|
**下载大小**: ~10GB
|
||||||
|
**下载时间**: 取决于网络速度(约10-30分钟)
|
||||||
|
|
||||||
|
### 方法2: git-lfs
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 安装 git-lfs
|
||||||
|
git lfs install
|
||||||
|
|
||||||
|
# 克隆模型仓库
|
||||||
|
cd /data/ymq/models
|
||||||
|
git clone https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B
|
||||||
|
```
|
||||||
|
|
||||||
|
### 方法3: wget/curl(单文件)
|
||||||
|
|
||||||
|
如果只需要特定文件,可以直接下载:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd /data/ymq/models/Wan-AI/Wan2.2-TI2V-5B
|
||||||
|
|
||||||
|
# 下载模型文件(示例)
|
||||||
|
wget https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B/resolve/main/diffusion_pytorch_model-00001-of-00003.safetensors
|
||||||
|
wget https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B/resolve/main/diffusion_pytorch_model-00002-of-00003.safetensors
|
||||||
|
wget https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B/resolve/main/diffusion_pytorch_model-00003-of-00003.safetensors
|
||||||
|
wget https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B/resolve/main/Wan2.2_VAE.pth
|
||||||
|
wget https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B/resolve/main/config.json
|
||||||
|
```
|
||||||
|
|
||||||
|
### 验证下载
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ls -lh /data/ymq/models/Wan-AI/Wan2.2-TI2V-5B/
|
||||||
|
# 应该看到 3个 .safetensors 文件(每个约3.3GB)+ VAE + 配置文件
|
||||||
|
```
|
||||||
|
|
||||||
