Issues with workflow?
I am interested in testing this model but I cannot get it to work with the supplied workflow, I run into "mat1 and mat2 shapes cannot be multiplied (512x2560 and 7680x3072)" error if I use your workflow, and if i run a workflow using the nunchaku dit loaders i get 'model_class' as the error. I seem to be able to use the nunchaku provided flux models fine but neither your chroma or z image work for me - Is there something I am missing? Thank you!
I am pushing for the official Nunchaku PR to be merged: https://github.com/nunchaku-ai/nunchaku/pull/916 Until then, if you want to try it out, you can copy transformer_chroma.py from the repository to nunchaku/models/transformers/transformer_chroma.py.This is a relatively low-performance version; a high-performance version still needs to wait for the PR to be approved.
Thank you for your prompt response, I will hold for the high performance version!
Because the underlying layers were modified for higher performance, but the Nunchaku maintainers aren't active enough, I will be releasing a new PR with smaller changes to ensure it gets approved.
@tonera
I noticed that your pull request has been closed. Does this mean that Chroma HD support is being dropped?
This is the new version:https://github.com/nunchaku-ai/nunchaku/pull/928
Thanks for all your hard work Tonera 👍
the Nunchaku maintainers aren't active enough ...
Yes, it has been a month since the last activity, which is concerning compared to the previous pace.
