HiDreamImageTransformer2DModel
HiDreamImageTransformer2DModel
A Transformer model for image-like data from HiDream-I1.
The model can be loaded with the following code snippet.
from diffusers import HiDreamImageTransformer2DModel
transformer = HiDreamImageTransformer2DModel.from_pretrained("HiDream-ai/HiDream-I1-Full", subfolder="transformer", torch_dtype=torch.bfloat16)Loading GGUF quantized checkpoints for HiDream-I1
GGUF checkpoints for the HiDreamImageTransformer2DModel can be loaded using ~FromOriginalModelMixin.from_single_file

Parameters
- sample (
torch.Tensorof shape(batch_size, num_channels, height, width)or(batch size, num_vector_embeds - 1, num_latent_pixels)if Transformer2DModel is discrete) — The hidden states output conditioned on theencoder_hidden_statesinput. If discrete, returns probability distributions for the unnoised latent pixels.
The output of Transformer2DModel.
