I AM USING RTX 3090. Got this error following install instructions and using the fp8 model...
If you are using comfyui do not use the model they are listing as it causes issues. Use this model and delete the patcher node

Tried but kept hanging after maybe 5 min.. anyone get this going w a 30xx series?
I'm having the same issue with my 3090 when trying out the fp8 distilled 13b model. Probably related to the q8 kernels
Nerdy Rodent compiled it, it didnt get it to work anyway....
https://github.com/nerdyrodent/LTX-Video-Q8-Kernels-3090
For now, I just bypassed this Q8Patch node, it works, though not sure if this is the best solution. In another issue, someone suggested to use a KJs model, you can search for that issue.
If you're on a GPU not identified as "hopper", "ada", or "blackwell" ā like Ampere (e.g. RTX 30xx cards like your 3080 Ti) ā none of the conditionals assign self_attn_func, and use_default is never set to True, so it crashes. I think the use_default should be set to True by default not false on line 37 of utils.py. Then the rest of the logic works for ada/hopper/blackwell it gets the specific settings and others get the default.
Changing use_default=True didn't help i'm guessing the default setup doesn't work either so its probably just never been fully tested on anything but hopper/ada/blackwell which means theres other problems with the default setting as well.
