AllegroTransformer3DModel
RhymesAI 在 Allegro: Open the Black Box of Commercial-Level Video Generation Model 中介绍了来自 Allegro 的 3D 数据扩散 Transformer 模型。
该模型可以通过以下代码片段加载。
from diffusers import AllegroTransformer3DModel
transformer = AllegroTransformer3DModel.from_pretrained("rhymes-ai/Allegro", subfolder="transformer", torch_dtype=torch.bfloat16).to("cuda")AllegroTransformer3DModel
class diffusers.AllegroTransformer3DModel

Transformer2DModelOutput
class diffusers.models.modeling_outputs.Transformer2DModelOutput
< 源 >( sample: torch.Tensor )
参数
- sample（形状为
(batch_size, num_channels, height, width)的torch.Tensor；如果 Transformer2DModel 是离散的，则为(batch size, num_vector_embeds - 1, num_latent_pixels)） — 基于encoder_hidden_states输入的隐藏状态输出。如果是离散的，则返回未去噪潜在像素的概率分布。
