Kijai Framepack LoadFramePackModel missing sdpa

I downloaded the recommended workflog, but i cannot get it working. This error occurs: LoadFramePackModel: - Value not in list: load_device: ‘sdpa’ not in [‘main_device’, ‘offload_device’]

I gave it a try with the main_device option, but that failed. Where can i get sdpa? Is there something to be installed? I tried pip install sdpa-python, but it didn’t help.
