## 环境配置

### Docker（方法一）
    
    docker pull image.sourcefind.cn:5000/dcu/admin/base/pytorch:2.3.0-ubuntu22.04-dtk24.04.3-py3.10

    docker run --shm-size 100g --network=host --name=wan --privileged --device=/dev/kfd --device=/dev/dri --group-add video --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -v 项目地址(绝对路径):/home/ -v /opt/hyhal:/opt/hyhal:ro -it <your IMAGE ID> bash

    pip install -r requirements.txt

    pip install "xfuser>=0.4" --no-deps torch

    bash modified/fix.sh

### Dockerfile（方法二）

    docker build -t <IMAGE_NAME>:<TAG> .

    docker run --shm-size 100g --network=host --name=wan --privileged --device=/dev/kfd --device=/dev/dri --group-add video --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -v 项目地址(绝对路径):/home/ -v /opt/hyhal:/opt/hyhal:ro -it <your IMAGE ID> bash
    
    pip install -r requirements.txt

    pip install "xfuser>=0.4" --no-deps torch

    bash modified/fix.sh

### Anaconda（方法三）

1、关于本项目DCU显卡所需的特殊深度学习库可从光合开发者社区下载安装： https://developer.hpccube.com/tool/

```
DTK驱动:dtk24.04.3
python:python3.10
torch:2.3.0
torchvision:0.18.1
torchaudio:2.1.2
triton:2.1.0
vllm:0.6.2
flash-attn:2.6.1
deepspeed:0.14.2
apex:1.3.0
xformers:0.0.25
transformers:4.48.0
```

2、其他非特殊库直接按照requirements.txt安装

```
pip install -r requirements.txt

pip install "xfuser>=0.4" --no-deps torch

# 需要参考 modified/fix.sh中的命令修改相应位置的代码
```

### 文本-视频生成

1、单卡

<!-- # # 14B模型支持480/720P
# python generate.py  --task t2v-14B --size 832*480 --ckpt_dir models/Wan2.1-T2V-14B --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage." -->

```bash
# 1.3B模型支持480P
python generate.py  --task t2v-1.3B --size 832*480 --ckpt_dir models/Wan2.1-T2V-1.3B --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage."
```

注意：若遇到显存不够的问题，可以尝试`--offload_model True`，`--t5_cpu`

2、多卡

```bash
# 1.3B
torchrun --nproc_per_node=4 generate.py --task t2v-1.3B --size 832*480 --ckpt_dir models/Wan2.1-T2V-1.3B --dit_fsdp --t5_fsdp --ulysses_size 4 --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage."

# 14B
torchrun --nproc_per_node=4 generate.py --task t2v-14B --size 1280*720 --ckpt_dir models/Wan2.1-T2V-14B --dit_fsdp --t5_fsdp --ulysses_size 4 --prompt "Two anthropomorphic cats in comfy boxing gear and bright gloves fight intensely on a spotlighted stage."
```

```bash

```bash
python generate.py --task i2v-14B --size 1280*720 --ckpt_dir models/Wan2.1-I2V-14B-720P --image examples/i2v_input.JPG --prompt "Summer beach vacation style, a white cat wearing sunglasses sits on a surfboard. The fluffy-furred feline gazes directly at the camera with a relaxed expression. Blurred beach scenery forms the background featuring crystal-clear waters, distant green hills, and a blue sky dotted with white clouds. The cat assumes a naturally relaxed posture, as if savoring the sea breeze and warm sunlight. A close-up shot highlights the feline's intricate details and the refreshing atmosphere of the seaside."
