1. Download classifier: https://openaipublic.blob.core.windows.net/diffusion/jul-2021/64x64_classifier.pt
2. Download diffusion model: https://openaipublic.blob.core.windows.net/diffusion/jul-2021/64x64_diffusion.pt
3. put classifier and diffusion model in "models" 
4. Run command 'bash bash_scripts/IM64_uncond_ots_compt.sh' to do sampling on IMN64x64 conditional diffusion model. The code is hard fix for the reviewing purpose. The full code will be released after acceptance.
