I greet you Ladies and Gentleman,

Today i came to the conclusion to fix my Sageattention which is not working.I had the Issue where i tried a custom Workflow Image to Video with Hunyuan. But the problem is that i can only use comfy and sdpa,flash attention and sageattention are not working for me.I tried to manually install Sageattention and dropped it onto my file and it did not work. I asked alot of Discord Groups and i didnt got any help and thats why im writing this Issue on Github.

Best Regards :)

If you provide no information other than simply saying that it doesn't work, no one will be able to help you.

Your execution environment, ComfyUI version, CLI options, full logs, and workflow—

all of these are necessary.

Same here, iv spent hours doing everything, and it even lists sage v1 and triton as installed but cannot manage to get sage 2 going and comfyui does not recognize sage 1 install.

Make sure you have Triton already installed (see #7421 (comment))

In the ComfyUI desktop open up the terminal and navigate to the .venv fol 68C5 der
run pip install SageAttention
