Hi,

I am running the code "as is" on Google Colab (GPU runtime). Upon executing the following line in the code
!python inference_gfpgan.py --upscale 2 --test_path inputs/upload --save_root results --model_path experiments/pretrained_models/GFPGANCleanv1-NoCE-C2.pth --bg_upsampler realesrgan, I am getting the following error:

Traceback (most recent call last):
  File "inference_gfpgan.py", line 113, in <module>
    main()
  File "inference_gfpgan.py", line 56, in main
    half=True)  # need to set False in CPU mode
  File "/usr/local/lib/python3.7/dist-packages/realesrgan/utils.py", line 49, in __init__
    model.load_state_dict(loadnet[keyname], strict=True)
AttributeError: 'NoneType' object has no attribute 'load_state_dict'

It looks like the external code for ESR GAN has changed.

How do I get around this error?
