HiDreamImageTransformer2DModel
來自 HiDream-I1 的用於影像類資料的 Transformer 模型。
該模型可以透過以下程式碼片段載入。
from diffusers import HiDreamImageTransformer2DModel
transformer = HiDreamImageTransformer2DModel.from_pretrained("HiDream-ai/HiDream-I1-Full", subfolder="transformer", torch_dtype=torch.bfloat16)為 HiDream-I1 載入 GGUF 量化檢查點
可以使用 ~FromOriginalModelMixin.from_single_file 載入 HiDreamImageTransformer2DModel 的 GGUF 檢查點。

引數
- sample (形狀為
(batch_size, num_channels, height, width)的torch.Tensor或當 Transformer2DModel 為離散時，形狀為(batch size, num_vector_embeds - 1, num_latent_pixels)) — 在encoder_hidden_states輸入條件下輸出的隱藏狀態。如果是離散的，則返回未去噪的潛在畫素的機率分佈。
