Please can some one help me to backup to the nightly version Dev1.0.0 20250825 plz

[badraymen]

since the last update for the new version of nunchaku, i lost my workflow tools, i need to comeback to the functional nightly version Dev1.0.0 20250825 plz , how can i comeback and where i can find wheels ? this on disappear form realize

[lmxyy]

doesn't https://github.com/nunchaku-tech/nunchaku/releases/edit/v1.0.0dev20250830 work for you? This two wheels should behave the same. Next time I think we need to keep the nightly wheels for longer time.

@lmxyy
Dear Sir, I really appreciate your tremendous effort in this work and discovery that was a dream for some people.. The problem is that I tried them all from 23 to 09, but the problem is that the node has disappeared in all versions.. and it tells me: "nunchaku qwen dlit is missing" even after I deleted the nunchaku file from the custom nodes and reinstalled it.. it tells me the node does not exist.. Are there some steps that I may have forgotten? Please
I tried all types of qwen tensor from the original to gguf, but the work became very slow.. knowing that I updated comfyui. And since then I have had many errors, especially with RES4LYF Ksamplers. Believe me, I haven't had peace of mind for 3 days since the update, and I've become nervous and confused after starting a new project that's very important to me. I also noticed that the images have become more blurry with the 128-step nunchaku compared to the regular ksamler. Please help me.

I see. So you just need specifically 0823 wheel? Which python and PyTorch version do you need? I can build one for you.

**### as it is displayed on the photo, version 30 and 23 do not display the node "Nunchaku Qwen-Image DiT Loader"

I remember very well that I had version 25 which worked, and the node is displayed in the list, if not if you have a solution for this error displayed by this ksampler from RES4LYF it would be really great, everything works with the new dev 1.0.0 update except these two nodes displayed in the photo, it displays this error:**

I see. So you just need specifically 0823 wheel? Which python and PyTorch version do you need? I can build one for you.

---

i think this one: nunchaku-dev1.0.020250825+torch2.8-cp312-cp312-win_amd64.whl

[lmxyy]

Do you still need it?

I have this problem.. that's what happened to me with the new version, all what i need is to fix this issues only and i will be grateful 🥹☺️

I forget to say that when i change the bat file of comfy gpu with --highvram (everything work (especially the RES4LYF)but very very slow), but with the --normalvram the error back to my screen
