• encoder_hidden_states (torch.FloatTensor of shape (batch size, sequence_len, embed_dims)) -- Conditional embeddings (embeddings computed from the input conditions such as prompts) to use.
• text_encoder_layers (list of torch.Tensor) -- Per-block text encoder hidden states, one tensor per transformer block.
• pooled_projections (torch.FloatTensor of shape (batch_size, projection_dim)) -- Embeddings projected from the embeddings of input conditions.
• timestep ( torch.LongTensor) -- Used to indicate denoising step.
• img_ids (torch.Tensor) -- Image position ids used to compute the rotary positional embeddings.
• txt_ids (torch.Tensor) -- Text position ids used to compute the rotary positional embeddings.
• guidance (torch.Tensor, optional) -- Guidance scale embedding used for guidance-distilled variants of the model.
• joint_attention_kwargs (dict, optional) -- A kwargs dictionary that if specified is passed along to the AttentionProcessor as defined under self.processor in diffusers.models.attention_processor.
• return_dict (bool, optional, defaults to True) -- Whether or not to return a ~models.transformer_2d.Transformer2DModelOutput instead of a plain tuple.0If return_dict is True, an ~models.transformer_2d.Transformer2DModelOutput is returned, otherwise a tuple where the first element is the sample tensor.

Parameters:

patch_size (int) : Patch size to turn the input data into small patches.

in_channels (int, optional, defaults to 16) : The number of channels in the input.

num_layers (int, optional, defaults to 18) : The number of layers of MMDiT blocks to use.

num_single_layers (int, optional, defaults to 18) : The number of layers of single DiT blocks to use.

attention_head_dim (int, optional, defaults to 64) : The number of channels in each head.

num_attention_heads (int, optional, defaults to 18) : The number of heads to use for multi-head attention.

joint_attention_dim (int, optional) : The number of encoder_hidden_states dimensions to use.

pooled_projection_dim (int) : Number of dimensions to use when projecting the pooled_projections.

guidance_embeds (bool, defaults to False) : Whether to use guidance embeddings.

Returns:

If return_dict is True, an ~models.transformer_2d.Transformer2DModelOutput is returned, otherwise a tuple where the first element is the sample tensor.
