pipeline.push_to_hub("my-pipeline") The push_to_hub() function saves each component to a subfolder in the repository. Now you can reload the pipeline from your repository on the Hub: Copied pipeline = StableDiffusionPipeline.from_pretrained("your-namespace/my-pipeline") Privacy Set private=True in the push_to_hub() ...
Create a dataset for training There are many datasets on the Hub to train a model on, but if you can’t find one you’re interested in or want to use your own, you can create a dataset with the 🤗 Datasets library. The dataset structure depends on the task you want to train your model on. The most basic dataset structure...
data_dir/xxy.png
data_dir/[...]/xxz.png Pass the path to the dataset directory to the --train_data_dir argument, and then you can start training: Copied accelerate launch train_unconditional.py \
--train_data_dir <path-to-train-directory> \
<other-arguments> Upload your data to the Hub 💡 For more details and context about creating and uploading a dataset to the Hub, take a look at the Image search with 🤗 Datasets post. Start by creating a dataset with the ImageFolder feature, which creates an image column containing the PIL-encoded images. You can ...
# example 1: local folder
dataset = load_dataset("imagefolder", data_dir="path_to_your_folder")
# example 2: local files (supported formats are tar, gzip, zip, xz, rar, zstd)
dataset = load_dataset("imagefolder", data_files="path_to_zip_file")
# example 3: remote files (supported formats are tar, gzip, zip, xz, rar, zstd)
dataset = load_dataset(
"imagefolder",
data_files="https://download.microsoft.com/download/3/E/1/3E1C3F21-ECDB-4869-8368-6DEBA77B919F/kagglecatsanddogs_3367a.zip",
)
# example 4: providing several splits
dataset = load_dataset(
"imagefolder", data_files={"train": ["path/to/file1", "path/to/file2"], "test": ["path/to/file3", "path/to/file4"]}
) Then use the push_to_hub method to upload the dataset to the Hub: Copied # assuming you have ran the huggingface-cli login command in a terminal
dataset.push_to_hub("name_of_your_dataset")
# if you want to push to a private repo, simply pass private=True:
dataset.push_to_hub("name_of_your_dataset", private=True) Now the dataset is available for training by passing the dataset name to the --dataset_name argument: Copied accelerate launch --mixed_precision="fp16" train_text_to_image.py \
--pretrained_model_name_or_path="runwayml/stable-diffusion-v1-5" \
--dataset_name="name_of_your_dataset" \
<other-arguments> Next steps Now that you’ve created a dataset, you can plug it into the train_data_dir (if your dataset is local) or dataset_name (if your dataset is on the Hub) arguments of a training script. For your next steps, feel free to try and use your dataset to train a model for unconditional generation o...
Latent upscaler The Stable Diffusion latent upscaler model was created by Katherine Crowson in collaboration with Stability AI. It is used to enhance the output image resolution by a factor of 2 (see this demo notebook for a demonstration of the original implementation). Make sure to check out the Stable Diffusion Tips...
Variational Auto-Encoder (VAE) model to encode and decode images to and from latent representations. text_encoder (CLIPTextModel) —
Frozen text-encoder (clip-vit-large-patch14). tokenizer (CLIPTokenizer) —
A CLIPTokenizer to tokenize text. unet (UNet2DConditionModel) —
A UNet2DConditionModel to denoise the encoded image latents. scheduler (SchedulerMixin) —
A EulerDiscreteScheduler to be used in combination with unet to denoise the encoded image latents. Pipeline for upscaling Stable Diffusion output image resolution by a factor of 2. This model inherits from DiffusionPipeline. Check the superclass documentation for the generic methods
implemented for all pipelines (downloading, saving, running on a particular device, etc.). The pipeline also inherits the following loading methods: from_single_file() for loading .ckpt files __call__ < source > ( prompt: Union image: Union = None num_inference_steps: int = 75 guidance_scale: float = 9.0 negative_pro...
The prompt or prompts to guide image upscaling. image (torch.FloatTensor, PIL.Image.Image, np.ndarray, List[torch.FloatTensor], List[PIL.Image.Image], or List[np.ndarray]) —
Image or tensor representing an image batch to be upscaled. If it’s a tensor, it can be either a
latent output from a Stable Diffusion model or an image tensor in the range [-1, 1]. It is considered
a latent if image.shape[1] is 4; otherwise, it is considered to be an image representation and
encoded using this pipeline’s vae encoder. num_inference_steps (int, optional, defaults to 50) —
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
expense of slower inference. guidance_scale (float, optional, defaults to 7.5) —
A higher guidance scale value encourages the model to generate images closely linked to the text
prompt at the expense of lower image quality. Guidance scale is enabled when guidance_scale > 1. negative_prompt (str or List[str], optional) —
The prompt or prompts to guide what to not include in image generation. If not defined, you need to
pass negative_prompt_embeds instead. Ignored when not using guidance (guidance_scale < 1). eta (float, optional, defaults to 0.0) —
Corresponds to parameter eta (η) from the DDIM paper. Only applies
to the DDIMScheduler, and is ignored in other schedulers. generator (torch.Generator or List[torch.Generator], optional) —
A torch.Generator to make
