搭建安装CodeFormer

1.硬件

电脑：macOS 10.15.7

mkdir codeformer
cd codeformer
git clone https://github.com/sczhou/CodeFormer.git

以上包大部分都是可以通过 pip install -r requirements.txt 命令完成，但cmake和opencv-python总失败，后手动下载安装包，单独安装成功。

4.安装CodeFormer【依次执行以下命令】

python basicsr/setup.py develop
python scripts/download_pretrained_models.py facelib
python scripts/download_pretrained_models.py dlib
python scripts/download_pretrained_models.py CodeFormer

5.使用

CodeFormer源码的目录下（code_former/CodeFormer/inputs/），提供了很多测试图片
修复完的图片会存到code_former/CodeFormer/results/test_img_0.5目录下（留意命令行执行完的结果），也可以自定义路径

5.1电脑有显卡的可以使用下面命令（主要是 --bg_upsampler realesrgan --face_upsample 两个参数）

python inference_codeformer.py --bg_upsampler realesrgan --face_upsample --input_path ~/code_former/CodeFormer/inputs/masked_faces/00143.png 

Downloading: "https://github.com/sczhou/CodeFormer/releases/download/v0.1.0/RealESRGAN_x2plus.pth" to ~/code_former/CodeFormer/weights/realesrgan/RealESRGAN_x2plus.pth

# 第一次使用这个命令会下载，之后就不会下载了
Face detection model: retinaface_resnet50
Background upsampling: True, Face upsampling: True
[1/1] Processing: 00143.png
	detect 1 faces


All results are saved in results/test_img_0.5  # 修复完的图片会存到code_former/CodeFormer/results/test_img_0.5目录下

5.2电脑无显卡使用下面命令

python inference_codeformer.py --input_path ~/code_former/CodeFormer/inputs/masked_faces/00664.png 
Face detection model: retinaface_resnet50
Background upsampling: False, Face upsampling: False
[1/1] Processing: 00664.png
	detect 1 faces

All results are saved in results/test_img_0.5
