Instructions

We provide code in two sub-directories: Offline_RL_2D containing code for example toy 2D and offline RL experiments and images containing code (based on implementations of openai/guided-diffusion) for Imagenet experiments. See corresponding READMEs in each folder for instructions; scripts should be run from the respective directories.
