## PyTorch Implementation of [AnimeGANv2](https://github.com/TachibanaYoshino/AnimeGANv2) **Updates** * `2021-10-17` Add weights for [FacePortraitV2](#additional-model-weights). [](https://colab.research.google.com/github/bryandlee/animegan2-pytorch/blob/main/colab_demo.ipynb)  * `2021-11-07` Thanks to [ak92501](https://twitter.com/ak92501), a [web demo](https://huggingface.co/spaces/akhaliq/AnimeGANv2) is integrated to [Huggingface Spaces](https://huggingface.co/spaces) with [Gradio](https://github.com/gradio-app/gradio). [](https://huggingface.co/spaces/akhaliq/AnimeGANv2) * `2021-11-07` Thanks to [xhlulu](https://github.com/xhlulu), the `torch.hub` model is now available. See [Torch Hub Usage](#torch-hub-usage). ## Basic Usage **Inference** ``` python test.py --input_dir [image_folder_path] --device [cpu/cuda] ``` ## Torch Hub Usage You can load the model via `torch.hub`: ```python import torch model = torch.hub.load("bryandlee/animegan2-pytorch", "generator").eval() out = model(img_tensor) # BCHW tensor ``` Currently, the following `pretrained` shorthands are available: ```python model = torch.hub.load("bryandlee/animegan2-pytorch:main", "generator", pretrained="celeba_distill") model = torch.hub.load("bryandlee/animegan2-pytorch:main", "generator", pretrained="face_paint_512_v1") model = torch.hub.load("bryandlee/animegan2-pytorch:main", "generator", pretrained="face_paint_512_v2") model = torch.hub.load("bryandlee/animegan2-pytorch:main", "generator", pretrained="paprika") ``` You can also load the `face2paint` util function: ```python from PIL import Image face2paint = torch.hub.load("bryandlee/animegan2-pytorch:main", "face2paint", size=512) img = Image.open(...).convert("RGB") out = face2paint(model, img) ``` More details about `torch.hub` is in [the torch docs](https://pytorch.org/docs/stable/hub.html) ## Weight Conversion from the Original Repo (Tensorflow) 1. Install the [original repo's dependencies](https://github.com/TachibanaYoshino/AnimeGANv2#requirements): python 3.6, tensorflow 1.15.0-gpu 2. Install torch >= 1.7.1 3. Clone the original repo & run ``` git clone https://github.com/TachibanaYoshino/AnimeGANv2 python convert_weights.py ``` <details> <summary>samples</summary> <br> Results from converted `Paprika` style model (input image, original tensorflow result, pytorch result from left to right) <img src="./samples/compare/1.jpg" width="960"> &nbsp; <img src="./samples/compare/2.jpg" width="960"> &nbsp; <img src="./samples/compare/3.jpg" width="960"> &nbsp; </details> **Note:** Results from converted weights slightly different due to the [bilinear upsample issue](https://github.com/pytorch/pytorch/issues/10604) ## Additional Model Weights **Webtoon Face** [[ckpt]](https://drive.google.com/file/d/10T6F3-_RFOCJn6lMb-6mRmcISuYWJXGc) <details> <summary>samples</summary> Trained on <b>256x256</b> face images.
