Summary of Changes

Hello @akaitsuki-ii, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves an issue related to the compilation of transformer blocks by adjusting the compile_repeated_blocks method across different model architectures. It ensures that the Flux model properly compiles its single_blocks, while simultaneously correcting the WAN model's compilation process by removing an unnecessary or incorrect step for its single_blocks. This change aims to improve the accuracy and efficiency of model compilation for both Flux and WAN architectures.

Highlights

• Flux Model Compilation Fix: The compile_repeated_blocks method in the Flux model (flux_dit.py) has been updated to correctly include and compile self.single_blocks, ensuring all relevant blocks are processed during compilation.
• WAN Model Compilation Adjustment: The compile_repeated_blocks method in the WAN model (wan_dit.py) has been modified to remove the compilation of self.single_blocks, aligning its compilation logic with its specific architecture.

Code Review

This pull request addresses an issue with compiling repeated blocks. The change in diffsynth_engine/models/flux/flux_dit.py correctly adds compilation for single_blocks, which was previously missing. The change in diffsynth_engine/models/wan/wan_dit.py removes an erroneous loop over single_blocks, which do not exist in that class, thus preventing a potential AttributeError. Both changes are correct and improve the code's robustness. I've included one suggestion to improve code conciseness.

[gemini-code-assist]

For conciseness, you can combine the two loops into a single one. nn.ModuleList supports concatenation using the + operator, which makes the code more readable.
