## 运行环境 (Operating environment)
### Dependencies and Installation

```shell
# Create a conda environment and activate it
conda create -n pixart python==3.9.0
conda activate pixart
pip install torch==2.1.1 torchvision==0.16.1 torchaudio==2.1.1 --index-url https://download.pytorch.org/whl/cu118

# git clone the original repository
git clone https://github.com/PixArt-alpha/PixArt-alpha.git
cd PixArt-alpha

# Install from requirements.txt
pip install -r requirements.txt
```

## 代码范例 (Code example)
参数说明：只需提供prompt，即可完成图像生成任务

```python
from modelscope.pipelines import pipeline
input = {'prompt': 'A small cactus with a happy face in the Sahara desert.'}

inference = pipeline('my-pixart-task', model='aojie1997/cv_PixArt-alpha_text-to-image')
output = inference(input)
output.save('./result.png')
```
