the cache for Hunyuan in MMSingleStreamBlock

[ywlq]

Hello first of all thanks for your great project.

Why is update_cache commented out? Without it, doesn't this mean there's no token-wise caching for the single_stream blocks? Essentially, only the last line of this code block is actually effective, and all the preceding computations are unused.

That's correct. The version of ToCa compatible with TaylorSeer here is only an intermediate release. The code currently uploaded to HunyuanVideo does not fully support the complete ToCa implementation. You could try restoring the "update cache" line, which should allow you to obtain the ToCa version of HunyuanVideo.
However, it’s been a while, and my memory is a bit hazy, so please just take this as a reference. I might check it at some point in the future, but this project primarily focuses on TaylorSeer, which is a highly competent approach.
