环境安装

powershell 复制代码

# 创建虚拟环境facechain
conda create -n facechain python=3.8
conda activate facechain
# 克隆
GIT_LFS_SKIP_SMUDGE=1 git clone https://github.com/modelscope/facechain.git --depth 1
# 安装第三方库
cd facechain
pip install -r requirements.txt
pip install -U openmim
# 设置所需的CUDA，因为安装了多个版本的CUDA
export PATH=/home/xxx/.local/cuda-11.7/bin:$PATH
export LD_LIBRARY_PATH=LD_LIBRARY_PATH:/home/xxx/.local/cuda-11.7/lib64
export CUDA_HOME=/home/xxx/.local/cuda-11.7
# 安装mmcv
mim install mmcv-full==1.7.0

webui的运行方式

app.py文件增加临时文件存放位置，因为多个人使用同一个服务，gradio的临时文件会存放在/tmp/gradio下存在权限问题。
python 复制代码
```
 import tempfile
 tempfile.tempdir = './tmp'
```

app.py文件修改modelscope和huggingface的目录

python 复制代码

	import os
	os.environ['MODELSCOPE_CACHE'] = '/opt/buty/work/modelscope'
	os.environ['HF_HOME'] = '/opt/buty/work/huggingface'
	os.environ['CUDA_VISIBLE_DEVICES'] = '0'

snapdown 文件的路径使用临时文件存放位置还是有问题，需要修改/tmp/snapdown/目录的权限
powershell 复制代码
```
sudo chmod -R 777 /tmp/snapdown/
```
运行脚本
powershell 复制代码
```
    python app.py
```

命令行交互界面的运行方式

train_text_to_image_lora.py文件修改modelscope和huggingface的目录

python 复制代码

	import os
	os.environ['MODELSCOPE_CACHE'] = '/opt/buty/work/modelscope'
	os.environ['HF_HOME'] = '/opt/buty/work/huggingface'
	os.environ['CUDA_VISIBLE_DEVICES'] = '0'

模型训练

python 复制代码

PYTHONPATH=. sh train_lora.sh "ly261666/cv_portrait_model" "v2.0" "film/film" "./imgs" "./processed" "./output"

推理
python 复制代码
```
python run_inference.py
```
