# Structure

* `simulator.py`: all kinds of simulations, physics simulation, learned simulation. The common function is `def step(action)`.
* `policy.py`: all kinds of policies, random, teleop, and/or learned. The common function is `def generate_action(obs)`.
* `main.py`: the interface, the wrapper, nothing you really needs to know.
* `example/*.py`: all example goes here

# Usage
`python -m sim.example.___` be sure to config corresponding example, e.g., the ckpt path, quantization/no-quantization, image resolution, inference iterations, etc.
