Research direction
Start by reproducing the failure from demo_gradio.py and run it with CUDA_LAUNCH_BLOCKING=1 to identify the failing operation. Inspect diffusers_helper/models/hunyuan_video_packed.py, especially attn_varlen_func and the forward path around the reported lines; done means establishing the cause of the CUDA launch failure and confirming a reproducible fix or clear diagnosis.
