python: 安装DeOldify库:黑白图片上色(Python 3.7.15)

一，下载deoldify

1,官网:

https://deoldify.ai/

2,项目地址:

 https://github.com/jantic/DeOldify

3,用git下载到本地

[lhdop@blog soft]$ git clone https://github.com/jantic/DeOldify.git DeOldify

4,下载用到三个权重文件:

[lhdop@blog DeOldify]$ mkdir models
[lhdop@blog DeOldify]$ cd models/
[lhdop@blog models]$ wget https://data.deepai.org/deoldify/ColorizeArtistic_gen.pth
[lhdop@blog models]$ wget https://data.deepai.org/deoldify/ColorizeVideo_gen.pth

下面这个需要梯子，下载完后上传

https://www.dropbox.com/s/usf7uifrctqw9rl/ColorizeStable_gen.pth?dl=0

如图:

5,安装需要用到的依赖项

[lhdop@blog DeOldify]$ pip3 install -r requirements.txt

6,安装依赖项时，遇到报错的处理:

1,No matching distribution found for Pillow==9.1.0

参见:   

https://blog.imgtouch.com/index.php/2023/06/03/python-error-no-matching-distribution-found-for-pillow-9-1/

二，编写python代码:

setColor.py

from deoldify import device
from deoldify.device_id import DeviceId
#choices:  CPU, GPU0...GPU7
#device.set(device=DeviceId.GPU0)
device.set(device=DeviceId.CPU)
from deoldify.visualize import *
import sys
from pathlib import Path
plt.style.use('dark_background')
torch.backends.cudnn.benchmark=True

import warnings
warnings.filterwarnings("ignore", category=UserWarning, message=".*?Your .*? set is empty.*?")

colorizer = get_image_colorizer(artistic=True)

render_factor=35

source_path = sys.argv[1]

result_path = sys.argv[2]

result = colorizer.plot_transformed_image(path=source_path, render_factor=render_factor, compare=True)
if result is not None:
    result.save(result_path,quality=95)
    result.close

三，测试效果

 命令行运行

[lhdop@blog DeOldify]$ python3 setColor.py /home/lhdop/imgblack/woman.webp /home/lhdop/imgblack/womanc.jpg

which is smaller than what this DataLoader is going to create. Please be aware that excessive worker creation might 
get DataLoader running slow or even freeze, lower the worker number to avoid potential slowness/freeze if necessary.
