The [LatteTransformer3DModel](/docs/diffusers/v0.36.0/en/api/models/latte_transformer3d#diffusers.LatteTransformer3DModel) forward method.

**Parameters:**

hidden_states shape `(batch size, channel, num_frame, height, width)` : Input `hidden_states`.

timestep ( `torch.LongTensor`, *optional*) : Used to indicate denoising step. Optional timestep to be applied as an embedding in `AdaLayerNorm`.

encoder_hidden_states ( `torch.FloatTensor` of shape `(batch size, sequence len, embed dims)`, *optional*) : Conditional embeddings for cross attention layer. If not given, cross-attention defaults to self-attention.

encoder_attention_mask ( `torch.Tensor`, *optional*) : Cross-attention mask applied to `encoder_hidden_states`. Two formats supported:  * Mask `(batcheight, sequence_length)` True = keep, False = discard. * Bias `(batcheight, 1, sequence_length)` 0 = keep, -10000 = discard.  If `ndim == 2`: will be interpreted as a mask, then converted into a bias consistent with the format above. This bias will be added to the cross-attention scores.

enable_temporal_attentions : (`bool`, *optional*, defaults to `True`): Whether to enable temporal attentions.

return_dict (`bool`, *optional*, defaults to `True`) : Whether or not to return a `~models.unet_2d_condition.UNet2DConditionOutput` instead of a plain tuple.

**Returns:**

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