comfyanonymous 4871a36458 Cleanup some unused imports. 2024-01-21 21:51:22 -05:00
comfyanonymous d76a04b6ea Add unfinished ImageOnlyCheckpointSave node to save a SVD checkpoint.
This node is unfinished, SVD checkpoints saved with this node will
work with ComfyUI but not with anything else.

comfyanonymous 2395ae740a Make unclip more deterministic.
Pass a seed argument note that this might make old unclip images different.
2024-01-14 17:28:31 -05:00
comfyanonymous 10f2609fdd Add InpaintModelConditioning node.
This is an alternative to VAE Encode for inpaint that should work with
lower denoise.

This is a different take on #2501

comfyanonymous 8c6493578b Implement noise augmentation for SD 4X upscale model. 2024-01-03 14:27:11 -05:00
comfyanonymous a7874d1a8b Add support for the stable diffusion x4 upscaling model.
This is an old model.

Load the checkpoint like a regular one and use the new
SD_4XUpscale_Conditioning node.

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

comfyanonymous 2258f85159 Support stable zero 123 model.
To use it use the ImageOnlyCheckpointLoader to load the checkpoint and
the new Stable_Zero123 node.

comfyanonymous 3152023fbc Use inference dtype for unet memory usage estimation. 2023-12-11 23:50:38 -05:00
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 ba07cb748e Use faster manual cast for fp8 in unet. 2023-12-11 18:24:44 -05:00
comfyanonymous 31b0f6f3d8 UNET weights can now be stored in fp8.
--fp8_e4m3fn-unet and --fp8_e5m2-unet are the two different formats
supported by pytorch.

comfyanonymous 61a123a1e0 A different way of handling multiple images passed to SVD.
Previously when a list of 3 images [0, 1, 2] was used for a 6 frame video
they were concated like this:
[0, 1, 2, 0, 1, 2]

now they are concated like this:
[0, 0, 1, 1, 2, 2]

comfyanonymous 7c0f255de1 Clean up percent start/end and make controlnets work with sigmas. 2023-10-31 22:14:32 -04:00
comfyanonymous 1777b54d02 Sampling code changes.
apply_model in model_base now returns the denoised output.

This means that sampling_function now computes things on the denoised
output instead of the model output. This should make things more consistent
across current and future models.

comfyanonymous fcef47f06e Fix bug. 2023-06-28 00:38:07 -04:00
comfyanonymous 9b93b920be Add CheckpointSave node to save checkpoints.
The created checkpoints contain workflow metadata that can be loaded by
dragging them on top of the UI or loading them with the "Load" button.

Checkpoints will be saved in fp16 or fp32 depending on the format ComfyUI
is using for inference on your hardware. To force fp32 use: --force-fp32

Anything that patches the model weights like merging or loras will be
saved.

The output directory is currently set to: output/checkpoints but that might
change in the future.
