It's about time. Thanks. |
Replaces custom attention implementations with `SkyReelsV2AttnProcessor2_0` and the standard `Attention` module. Updates `WanAttentionBlock` to use `FP32LayerNorm` and `FeedForward`. Removes the `model_type` parameter, simplifying model architecture and attention block initialization.
Introduces new classes `SkyReelsV2ImageEmbedding` and `SkyReelsV2TimeTextImageEmbedding` for enhanced image and time-text processing. Refactors the `SkyReelsV2Transformer3DModel` to integrate these embeddings, updating the constructor parameters for better clarity and functionality. Removes unused classes and methods to streamline the codebase.
