comfyanonymous 36a7953142 Greatly improve lowvram sampling speed by getting rid of accelerate.
Let me know if this breaks anything.

comfyanonymous 77755ab8db Refactor comfy.ops
comfy.ops -> comfy.ops.disable_weight_init

This should make it more clear what they actually do.

Some unused code has also been removed.

comfyanonymous 00c0b2c507 Initialize text encoder to target dtype. 2023-08-23 21:01:15 -04:00
comfyanonymous d6e4b342e6 Support for Control Loras.
Control loras are controlnets where some of the weights are stored in
"lora" format: an up and a down low rank matrice that when multiplied
together and added to the unet weight give the controlnet weight.

This allows a much smaller memory footprint depending on the rank of the
matrices.

These controlnets are used just like regular ones.

comfyanonymous bb1f45d6e8 Properly disable weight initialization in clip models. 2023-06-14 20:13:08 -04:00
comfyanonymous 21f04fe632 Disable default weight values in unet conv2d for faster loading. 2023-06-14 19:46:08 -04:00
comfyanonymous 6971646b8b Speed up model loading a bit.
Default pytorch Linear initializes the weights which is useless and slow.
