When running this AI program on RTX2060, an error occurred and it could not be processed correctly.

Nobody has claimed this yet.

How do I solve this problem? ? ? ?

Start with webui/diffusers_helper/models/hunyuan_video_packed.py, especially attn_varlen_func, and run python -m xformers.info to verify the available operators. Compare the RTX2060 capability reported in the traceback with the attention path being selected; done means establishing whether this GPU can run the workload and documenting or implementing a supported path if the project scope includes one.
