Comfyui crash UserWarning: 1Torch was not compiled with flash attention.

[Svebo403]

Expected Behavior

Hello!
I have two problems! the first one doesn't seem to be so straightforward, because the program runs anyway, the second one always causes the program to crash when using the file: "flux1-dev-fp8.safetensors." I have attached the log file, and hope you can help me.

Actual Behavior

ComfyUI-Manager: installing dependencies done.
