This is the onnxruntime inference code for GFP-GAN: Towards Real-World Blind Face Restoration with Generative Facial Prior (CVPR 2021). Official code: https://github.com/TencentARC/GFPGAN

1、noise = out.new_empty(b, 1, h, w).normal_() in stylegan2_clean_arch.py can‘t be supported in ONNX. I move it out the Model class, like noise = Noise[i], the Noise is a list or others which prestores generated random noise.

2、the forward function of Model is very bad, especially stylegan, so many " if else " and class be reused. Like the StyleConv " in "useself.style_convs.append StyleConv ...". So I rewrite and make it in single forward.
