SD3Transformer2D

This class is useful when only loading weights into a [SD3Transformer2DModel]. If you need to load weights into the text encoder or a text encoder and SD3Transformer2DModel, check SD3LoraLoaderMixin class instead.

The [SD3Transformer2DLoadersMixin] class currently only loads IP-Adapter weights, but will be used in the future to save weights and load LoRAs.

Tip

To learn more about how to load LoRA weights, see the LoRA loading guide.
