import gradio as gr from convert import run_conversion from hub_utils import push_to_hub, save_model_card PRETRAINED_CKPT = "CompVis/stable-diffusion-v1-4" DESCRIPTION = """ This Space lets you convert KerasCV Stable Diffusion weights to a format compatible with [Diffusers](https://github.com/huggingface/diffusers) 🧨. This allows users to fine-tune using KerasCV and use the fine-tuned weights in Diffusers taking advantage of its nifty features (like [schedulers](https://huggingface.co/docs/diffusers/main/en/using-diffusers/schedulers), [fast attention](https://huggingface.co/docs/diffusers/optimization/fp16), etc.). Specifically, the Keras weights are first converted to PyTorch and then they are wrapped into a [`StableDiffusionPipeline`](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview). This pipeline is then pushed to the Hugging Face Hub given you have provided `your_hf_token`. ## Notes (important) * The Space downloads a couple of pre-trained weights and runs a dummy inference. Depending, on the machine type, the enture process can take anywhere between 2 - 5 minutes. * Only Stable Diffusion (v1) is supported as of now. In particular this checkpoint: [`"CompVis/stable-diffusion-v1-4"`](https://huggingface.co/CompVis/stable-diffusion-v1-4). * [This Colab Notebook](https://colab.research.google.com/drive/1RYY077IQbAJldg8FkK8HSEpNILKHEwLb?usp=sharing) was used to develop the conversion utilities initially. * Providing both `text_encoder_weights` and `unet_weights` is dependent on the fine-tuning task. Here are some _typical_ scenarios: * [DreamBooth](https://dreambooth.github.io/): Both text encoder and UNet * [Textual Inversion](https://textual-inversion.github.io/): Text encoder * [Traditional text2image fine-tuning](https://github.com/huggingface/diffusers/blob/main/examples/text_to_image): UNet **In case none of the `text_encoder_weights` and `unet_weights` is provided, nothing will be done.** * When providing the weights' links, ensure they're directly downloadable. Internally, the Space uses [`tf.keras.utils.get_file()`](https://www.tensorflow.org/api_docs/python/tf/keras/utils/get_file) to retrieve the weights locally. * If you don't provide `your_hf_token` the converted pipeline won't be pushed. Check [here](https://github.com/huggingface/diffusers/blob/31be42209ddfdb69d9640a777b32e9b5c6259bf0/examples/dreambooth/train_dreambooth_lora.py#L975) for an example on how you can change the scheduler of an already initialized `StableDiffusionPipeline`.
