Tutorial / Demonstration of Custom Training Loop about mushroom-rl HOT 1 CLOSED

Sorry, but I don't understand your point. If you want to render the environment, without learning, just call:

core.evaluate(n_steps=1000, render=True)

This will run the agent in the environment for 1000 steps and render.

You can make the same for a fixed number of episodes (2 in the examples):

core.evaluate(n_episodes=2, render=True)

If you need to add arbitrary code to the step, just use the callback_step parameter of the core.
Given that you can pass a class, you can activate and deactivate your callback behavior from your code.
This means that you can do whatever you want...

If you want to implement the interaction loop by yourself, you can just call the env to reset and step functions manually, but I don't see any general use case of doing such a thing and that couldn't be done with a callback or a dummy agent.
