Hi, please try to follow the steps outlined here in the README script of the parent repository for cifar10.

Thanks again for your kind help! I want to train a guided diffusion on cifar-10 dataset. It seems I need to both train a diffusion model and a 32x32 classifier on cifar-10. So I have the following two issues:

1. Is the model trained in the "improved diffusion" repository can be directly used in guided diffusion?
2. Can a 32x32 classifier be trained on the cifar-10 data set in 'guided difffusion'? It seems like the code only support 64x64,128x128,256x256,512x512 input size

1. If the image sizes match (which is not the case for CIFAR), then you can directly use from improved diffusion repository.
2. Yes, guided diffusion has no support for 32 image sizes (although, I suppose you can copy and re-use the code blocks for 32 image size from improved diffusion)

Thank you! I think i got what you mean. I suppose I can adapt the input and output layer of the classifier model and fine-tune it on cifar-10.
