Overview

These examples show how to run Diffuser in Diffusers. There are two ways to use the script, run_diffuser_locomotion.py.

The key option is a change of the variable n_guide_steps. When n_guide_steps=0, the trajectories are sampled from the diffusion model, but not fine-tuned to maximize reward in the environment. By default, n_guide_steps=2 to match the original implementation.

You will need some RL specific requirements to run the examples:
