Has colorization been removed or only disabled?

[Ghee36]

Generative facial prior is genius. Wonderful research

Was colorization removed or just disabled by feature? I was unable to locate color jitter or grey settings.

1. For inference, you can find the original model with colorization in readme.md
2. For training, the option file train_gfpgan_v1.yml contains colorization settings.

[Ghee36]

I am not experienced so I made what attempt I could. I changed references of the current file with "GFPGANv1.pth"; while I am unknowledgeable with training and am only trying to output images both color and B&W to test the accuracy.

If you want to use the original model with colorization, please see: https://github.com/TencentARC/GFPGAN/blob/master/PaperModel.md

I chose option 2 on both and added the code to the first cell.

Please create other "Github issues" for other issues.

As for the colorization, reply was above: there are 2 models now, one with and one without colorization.
cf. https://github.com/TencentARC/GFPGAN/releases/tag/v0.2.0

Apologies, those following issues correlate and result from an inexperienced attempt to follow the coders instructions. Total lack of Python experience or knowledge to copy/paste in the correct areas knowingly.

@Ghee36 If you want to use the original model, please see the instructions: https://github.com/TencentARC/GFPGAN/blob/master/PaperModel.md for installation and inference.

As for the SyntaxError: invalid syntax, it seems that it has some unsupported (invisible) characters.

[Ghee36]

I mirrored the changes from the original model to the current notebook.

Clone GFPGAN and enter the GFPGAN folder
%cd /content
!rm -rf GFPGAN
!git clone https://github.com/TencentARC/GFPGAN.git
%cd GFPGAN

Set up the environment
Install basicsr - https://github.com/xinntao/BasicSR
Set BASICSR_EXT=True to compile the cuda extensions in the BasicSR - It may take several minutes to compile, please be patient.
!BASICSR_EXT=True pip install basicsr
Install facexlib - https://github.com/xinntao/facexlib
We use face detection and face restoration helper in the facexlib package
!pip install facexlib
Install other depencencies
!pip install -r requirements.txt
!python setup.py develop
!pip install realesrgan # used for enhancing the background (non-face) regions
Download the pre-trained model
!wget https://github.com/TencentARC/GFPGAN/releases/download/v0.1.0/GFPGANv1.pth -P experiments/pretrained_models

Works good no problems

Now we use the GFPGAN to restore the above low-quality images
We use Real-ESRGAN for enhancing the background (non-face) regions
!rm -rf results
!python inference_gfpgan.py --upscale 2 --test_path inputs/upload --save_root results --model_path experiments/pretrained_models/GFPGANv1.pth --bg_upsampler realesrgan

!ls results/cmp

This provides errors despite no longer referencing GFPGANv1Clean(is this for color?)
