Increase maximum macOS version to 15.0.1 when forcing upcast attention (#5191) 2024-10-09 22:21:41 -04:00
comfyanonymous e38c94228b Add a weight_dtype fp8_e4m3fn_fast to the Diffusion Model Loader node.
This is used to load weights in fp8 and use fp8 matrix multiplication.

Generalize MacOS version check for force-upcast-attention (#4548)
This code automatically forces upcasting attention for MacOS versions 14.5 and 14.6. My computer returns the string "14.6.1" for `platform.mac_ver()[0]`, so this generalizes the comparison to catch more versions.

I am running MacOS Sonoma 14.6.1 (latest version) and was seeing black image generation on previously functional workflows after recent software updates. This PR solved the issue for me.

comfyanonymous 843a7ff70c fp16 is actually faster than fp32 on a GTX 1080. 2024-08-21 23:23:50 -04:00

comfyanonymous 03ec517afb Remove useless line, adjust windows default reserved vram. 2024-08-21 00:47:19 -04:00
comfyanonymous 9953f22fce Add --fast argument to enable experimental optimizations.
Optimizations that might break things/lower quality will be put behind
this flag first and might be enabled by default in the future.

Currently the only optimization is float8_e4m3fn matrix multiplication on
4000/ADA series Nvidia cards or later. If you have one of these cards you
will see a speed boost when using fp8_e4m3fn flux for example.

comfyanonymous 1b3eee672c Fix potential issue with multi devices. 2024-08-20 10:46:36 -04:00
comfyanonymous 045377ea89 Add a --reserve-vram argument if you don't want comfy to use all of it.
--reserve-vram 1.0 for example will make ComfyUI try to keep 1GB vram free.

This can also be useful if workflows are failing because of OOM errors but
in that case please report it if --reserve-vram improves your situation.
