AssertionError: BNB bad weight without parent layer! BNB bad weight without parent layer!

[elen07zz]

Using the latest commit 2f0555f7dc3f2d06b3a3cc238a4fa2b72e11e28d I get this error when I use a Lora. Using either of these two modelsl: flux1-dev-bnb-nf4-v2 and flux-dev-Q8_0.ggguf

same here.

same - also, when I get a lora to load it doesn't change the image anymore. Yesterday it worked fine, but I updated Forge today - guess something broke. The swap location seems to make a difference too, although I can't see a clear pattern yet.

I had to revert two commits back to get it going again.

git checkout 394da01959ae09acca361dc2be0e559ca26829d4

[HelloWarcraft]

I tried git checkout command, swith to the repo of several hours ago:

git clone https://github.com/lllyasviel/stable-diffusion-webui-forge
cd ~/stable-diffusion-webui-forge
git checkout 6e6e5c21622a02f6978b0ed21e4a9557c8b49913 # commit at "do some profile on 3090", avoid "AssertionError: BNB bad weight"

Then the "Patching LoRAs" process goes fine：

git checkout 394da01959ae09acca361dc2be0e559ca26829d4

made a alternative run.bat so people can hop back to that specific version https://github.com/lllyasviel/stable-diffusion-webui-forge/issues/1216

Temp solution: change run.bat file then change to commit: 394da01959ae09acca361dc2be0e559ca26829d4

same problem

[AdamNizol]

new update seems to have fixed it

[rbrtwtrs]

Can confirm. All better now.
