I've forked Forge and updated (the most I could) to upstream dev A1111 changes!

Hi there guys, hope is all going good.

I decided after forge not being updated after ~5 months, that it was missing a lot of important or small performance updates from A1111, that I should update it so it is more usable and more with the times if it's needed.

So I went, commit by commit from 5 months ago, up to today's updates of the dev branch of A1111 (https://github.com/AUTOMATIC1111/stable-diffusion-webui/commits/dev) and updated the code, manually, from the dev2 branch of forge (https://github.com/lllyasviel/stable-diffusion-webui-forge/commits/dev2) to see which could be merged or not, and which conflicts as well.

Here is the fork and branch (very important!): https://github.com/Panchovix/stable-diffusion-webui-forge/tree/dev_upstream_a1111

Make sure it is on dev_upstream_a111

All the updates are on the dev_upstream_a1111 branch and it should work correctly.

Some of the additions that it were missing:

  • Scheduler Selection
  • DoRA Support
  • Small Performance Optimizations (based on small tests on txt2img, it is a bit faster than Forge on a RTX 4090 and SDXL)
  • Refiner bugfixes
  • Negative Guidance minimum sigma all steps (to apply NGMS)
  • Optimized cache
  • Among lot of other things of the past 5 months.

If you want to test even more new things, I have added some custom schedulers as well (WIPs), you can find them on https://github.com/Panchovix/stable-diffusion-webui-forge/commits/dev_upstream_a1111_customschedulers/

  • CFG++
  • VP (Variance Preserving)
  • SD Turbo
  • AYS GITS
  • AYS 11 steps
  • AYS 32 steps

What doesn't work/I couldn't/didn't know how to merge/fix:

  • Soft Inpainting (I had to edit sd_samplers_cfg_denoiser.py to apply some A1111 changes, so I couldn't directly apply https://github.com/lllyasviel/stable-diffusion-webui-forge/pull/494)
  • SD3 (Since forge has it's own unet implementation, I didn't tinker on implementing it)
  • Callback order (https://github.com/AUTOMATIC1111/stable-diffusion-webui/commit/5bd27247658f2442bd4f08e5922afff7324a357a), specifically because the forge implementation of modules doesn't have script_callbacks. So it broke the included controlnet extension and ui_settings.py.
  • Didn't tinker much about changes that affect extensions-builtin\Lora, since forge does it mostly on ldm_patched\modules.
  • precision-half (forge should have this by default)
  • New "is_sdxl" flag (sdxl works fine, but there are some new things that don't work without this flag)
  • DDIM CFG++ (because the edit on sd_samplers_cfg_denoiser.py)
  • Probably others things

The list (but not all) I couldn't/didn't know how to merge/fix is here: https://pastebin.com/sMCfqBua.

I have in mind to keep the updates and the forge speeds, so any help, is really really appreciated! And if you see any issue, please raise it on github so I or everyone can check it to fix it!

If you have a NVIDIA card, I suggest to use --cuda-malloc --cuda-stream --pin-shared-memory to get more performance.

After ~20 hours of coding for this, finally sleep...

Happy genning!

Scam alert: Fake but functional 4090s are relabelled 3080 TIs

7 Julio 2024 at 13:06

As the title says. This elaborate scam sends a working underpowered last gen relabelled card as explained here:

https://www.techspot.com/news/103700-incredibly-detailed-scam-relabels-rtx-3080-tis-rtx.html

I often see hardware questions and deal posts here so I wanted to reiterate: If it looks too good to be true, then it probably is! Only buy from very reputable sellers.

Stay safe, folks!

CGI Blender + ComfyUI

CGI Blender + ComfyUI

I used FSPY and Blender to incorporate my 3D animation made with the 3D motion capture project "Freemocap." This allows me to create a shadow in a realistic way. After creating an alpha mask and doing a style transfer with ComfyUI, I did a bit of compositing, and the result is as follows:

What's the best way to learn about diffusion in deep?

7 Julio 2024 at 09:37

I learned about transformers through Andrej karapathy's and 3blue1brown videos

Is there any good video or article on diffusion which can help me with reproducing some good enough diffusion models or controlnets by myself.

I'm working on generating textile weave patterns with diffusion both weave and images are represented on a grid but weave have some constraints unlike images.
