7242b5ff62 FIX Test to ignore warning for enable_lora_hotswap (#12421)
I noticed that the test should be for the option check_compiled="ignore"
but it was using check_compiled="warn". This has been fixed, now the
correct argument is passed.

However, the fact that the test passed means that it was incorrect to
begin with. The way that logs are collected does not collect the
logger.warning call here (not sure why). To amend this, I'm now using
assertNoLogs. With this change, the test correctly fails when the wrong
argument is passed.

* style

* Refactor: Remove hardcoded `torch.bfloat16` cast in attention

* Refactor: Simplify data type handling in transformer model

Removes unnecessary data type conversions for the FPS embedding and timestep projection.

This change simplifies the forward pass by relying on the inherent data types of the tensors.

* Refactor: Remove `fps_projection` from `_keep_in_fp32_modules` in `SkyReelsV2Transformer3DModel`

* Update src/diffusers/models/transformers/transformer_skyreels_v2.py

Co-authored-by: Aryan <contact.aryanvs@gmail.com>

* Refactor: Remove unused flags and simplify attention mask handling in SkyReelsV2AttnProcessor2_0 and SkyReelsV2Transformer3DModel

Refactor: Simplify causal attention logic in SkyReelsV2

Removes the `flag_causal_attention` and `_flag_ar_attention` flags to simplify the implementation.

The decision to apply a causal attention mask is now based directly on the `num_frame_per_block` configuration, eliminating redundant flags and conditional checks. This streamlines the attention mechanism and simplifies the `set_ar_attention` methods.

* Refactor: Clarify variable names for latent frames

Renames `base_num_frames` to `base_latent_num_frames` to make it explicit that the variable refers to the number of frames in the latent space.

This change improves code readability and reduces potential confusion between latent frames and decoded video frames.

The `num_frames` parameter in `generate_timestep_matrix` is also renamed to `num_latent_frames` for consistency.

* Enhance documentation: Add detailed docstring for timestep matrix generation in SkyReelsV2DiffusionForcingPipeline

* Docs: Clarify long video chunking in pipeline docstring

Improves the explanation of long video processing within the pipeline's docstring.

* style

* fix-copies

* Refactor parameter names for clarity in SkyReelsV2DiffusionForcingImageToVideoPipeline and SkyReelsV2DiffusionForcingVideoToVideoPipeline

* Refactor: Avoid VAE roundtrip in long video generation

Improves performance and quality for long video generation by operating entirely in latent space during the iterative generation process.

Instead of decoding latents to video and then re-encoding the overlapping section for the next chunk, this change passes the generated latents directly between iterations.

This avoids a computationally expensive and potentially lossy VAE decode/encode cycle within the loop. The full video is now decoded only once from the accumulated latents at the end of the process.

* Refactor: Rename prefix_video_latents_length to prefix_video_latents_frames for clarity

* Refactor: Rename num_latent_frames to current_num_latent_frames for clarity in SkyReelsV2DiffusionForcingImageToVideoPipeline

* Refactor: Enhance long video generation logic and improve latent handling in SkyReelsV2DiffusionForcingImageToVideoPipeline

Refactor: Unify video generation and pass latents directly

Unifies the separate code paths for short and long video generation into a single, streamlined loop.

This change eliminates the inefficient decode-encode cycle during long video generation. Instead of converting latents to pixel-space video between chunks, the pipeline now passes the generated latents directly to the next iteration.

This improves performance, avoids potential quality loss from intermediate VAE steps, and enhances code maintainability by removing significant duplication.

* style

* Refactor: Remove overlap_history parameter and streamline long video generation logic in SkyReelsV2DiffusionForcingImageToVideoPipeline

Refactor: Streamline long video generation logic

Removes the `overlap_history` parameter and simplifies the conditioning process for long video generation.

This change avoids a redundant VAE encoding step by directly using latent frames from the previous chunk for conditioning. It also moves image preprocessing outside the main generation loop to prevent repeated computations and clarifies the handling of prefix latents.

* style

* Refactor latent handling in i2v diffusion forcing pipeline

Improves the latent conditioning and accumulation logic within the image-to-video diffusion forcing loop.

- Corrects the splitting of the initial conditioning tensor to robustly handle both even and odd lengths.
- Simplifies how latents are accumulated across iterations for long video generation.
- Ensures the final latents are trimmed correctly before decoding only when a `last_image` is provided.

* Refactor: Remove overlap_history parameter from SkyReelsV2DiffusionForcingImageToVideoPipeline

* Refactor: Adjust video_latents parameter handling in prepare_latents method

* style

* Refactor: Update long video iteration print statements for clarity

* Fix: Update transformer config with dynamic causal block size

Updates the SkyReelsV2 pipelines to correctly set the `causal_block_size` in the transformer's configuration when it's provided during a pipeline call.

This ensures the model configuration reflects the user's specified setting for the inference run. The `set_ar_attention` method is also renamed to `_set_ar_attention` to mark it as an internal helper.

* style

* Refactor: Adjust video input size and expected output shape in inference test

* Refactor: Rename video variables for clarity in SkyReelsV2DiffusionForcingVideoToVideoPipeline

* Docs: Clarify time embedding logic in SkyReelsV2

Adds comments to explain the handling of different time embedding tensor dimensions.

A 2D tensor is used for standard models with a single time embedding per batch, while a 3D tensor is used for Diffusion Forcing models where each frame has its own time embedding. This clarifies the expected input for different model variations.

* Docs: Update SkyReels V2 pipeline examples

Updates the docstring examples for the SkyReels V2 pipelines to reflect current best practices and API changes.

- Removes the `shift` parameter from pipeline call examples, as it is now configured directly on the scheduler.
- Replaces the `set_ar_attention` method call with the `causal_block_size` argument in the pipeline call for diffusion forcing examples.
- Adjusts recommended parameters for I2V and V2V examples, including inference steps, guidance scale, and `ar_step`.

* Refactor: Remove `shift` parameter from SkyReelsV2 pipelines

Removes the `shift` parameter from the call signature of all SkyReelsV2 pipelines.

This parameter is a scheduler-specific configuration and should be set directly on the scheduler during its initialization, rather than being passed at runtime through the pipeline. This change simplifies the pipeline API.

Usage examples are updated to reflect that the `shift` value should now be passed when creating the `FlowMatchUniPCMultistepScheduler`.

* Refactors SkyReelsV2 image-to-video tests and adds last image case

Simplifies the test suite by removing a duplicated test class and streamlining the dummy component and input generation.

Adds a new test to verify the pipeline's behavior when a `last_image` is provided as input for conditioning.

* test: Add image components to SkyReelsV2 pipeline test

Adds the `image_encoder` and `image_processor` to the test components for the image-to-video pipeline.

Also replaces a hardcoded value for the positional embedding sequence length with a more descriptive calculation, improving clarity.

* test: Add callback configuration test for SkyReelsV2DiffusionForcingVideoToVideoPipeline

test: Add callback test for SkyReelsV2DFV2V pipeline

Adds a test to validate the callback functionality for the `SkyReelsV2DiffusionForcingVideoToVideoPipeline`.

This test confirms that `callback_on_step_end` is invoked correctly and can modify the pipeline's state during inference. It uses a callback to dynamically increase the `guidance_scale` and asserts that the final value is as expected.

The implementation correctly accounts for the nested denoising loops present in diffusion forcing pipelines.

* style

* fix: Update image_encoder type to CLIPVisionModelWithProjection in SkyReelsV2ImageToVideoPipeline

* UP

* Add conversion support for SkyReels-V2-FLF2V models

Adds configurations for three new FLF2V model variants (1.3B-540P, 14B-540P, and 14B-720P) to the conversion script.

This change also introduces specific handling to zero out the image positional embeddings for these models and updates the main script to correctly initialize the image-to-video pipeline.

* Docs: Update and simplify SkyReels V2 usage examples

Simplifies the text-to-video example by removing the manual group offloading configuration, making it more straightforward.

Adds comments to pipeline parameters to clarify their purpose and provides guidance for different resolutions and long video generation.

Introduces a new section with a code example for the video-to-video pipeline.

* style

* docs: Add SkyReels-V2 FLF2V 1.3B model to supported models list

* docs: Update SkyReels-V2 documentation

* Move the initialization of the `gradient_checkpointing` attribute to its suggested location.

* Refactor: Use logger for long video progress messages

Replaces `print()` calls with `logger.debug()` for reporting progress during long video generation in SkyReelsV2DF pipelines.

This change reduces console output verbosity for standard runs while allowing developers to view progress by enabling debug-level logging.

* Refactor SkyReelsV2 timestep embedding into a module

Extract the sinusoidal timestep embedding logic into a new `SkyReelsV2Timesteps` `nn.Module`.

This change encapsulates the embedding generation, which simplifies the `SkyReelsV2TimeTextImageEmbedding` class and improves code modularity.

* Fix: Preserve original shape in timestep embeddings

Reshapes the timestep embedding tensor to match the original input shape.

This ensures that batched timestep inputs retain their batch dimension after embedding, preventing potential shape mismatches.

* style

* Refactor: Move SkyReelsV2Timesteps to model file

Colocates the `SkyReelsV2Timesteps` class with the SkyReelsV2 transformer model.

This change moves model-specific timestep embedding logic from the general embeddings module to the transformer's own file, improving modularity and making the model more self-contained.

* Refactor parameter dtype retrieval to use utility function

Replaces manual parameter iteration with the `get_parameter_dtype` helper to determine the time embedder's data type.

This change improves code readability and centralizes the logic.

* Add comments to track the tensor shape transformations

* Add copied froms

* style

* fix-copies

* up

* Remove FlowMatchUniPCMultistepScheduler

Deletes the `FlowMatchUniPCMultistepScheduler` as it is no longer being used.

* Refactor: Replace FlowMatchUniPC scheduler with UniPC

Removes the `FlowMatchUniPCMultistepScheduler` and integrates its functionality into the existing `UniPCMultistepScheduler`.

This consolidation is achieved by using the `use_flow_sigmas=True` parameter in `UniPCMultistepScheduler`, simplifying the scheduler API and reducing code duplication. All usages, documentation, and tests are updated accordingly.

* style

* Remove text_encoder parameter from SkyReelsV2DiffusionForcingPipeline initialization

* Docs: Rename `pipe` to `pipeline` in SkyReels examples

Updates the variable name from `pipe` to `pipeline` across all SkyReels V2 documentation examples. This change improves clarity and consistency.

* Fix: Rename shift parameter to flow_shift in SkyReels-V2 examples

* Fix: Rename shift parameter to flow_shift in example documentation across SkyReels-V2 files

* Fix: Rename shift parameter to flow_shift in UniPCMultistepScheduler initialization across SkyReels test files

* Removes unused generator argument from scheduler step

The `generator` parameter is not used by the scheduler's `step` method within the SkyReelsV2 diffusion forcing pipelines. This change removes the unnecessary argument from the method call for code clarity and consistency.

* Fix: Update time_embedder_dtype assignment to use the first parameter's dtype in SkyReelsV2TimeTextImageEmbedding

* style

* Refactor: Use get_parameter_dtype utility function

Replaces manual parameter iteration with the `get_parameter_dtype` helper.

* Fix: Prevent (potential) error in parameter dtype check

Adds a check to ensure the `_keep_in_fp32_modules` attribute exists on a parameter before it is accessed.

This prevents a potential `AttributeError`, making the utility function more robust when used with models that do not define this attribute.
