## Jumanji @ ICLR 2024

Jumanji has been accepted at [ICLR 2024](https://iclr.cc/), check out our [research paper](https://arxiv.org/abs/2306.09884).

## Welcome to the Jungle! 🌴

Jumanji is a diverse suite of scalable reinforcement learning environments written in JAX. It now features 22 environments!

Jumanji is helping pioneer a new wave of hardware-accelerated research and development in the

field of RL. Jumanji's high-speed environments enable faster iteration and large-scale

experimentation while simultaneously reducing complexity. Originating in the research team at

[InstaDeep](https://www.instadeep.com/), Jumanji is now developed jointly with the open-source

community. To join us in these efforts, reach out, raise issues and read our

[contribution guidelines](https://github.com/instadeepai/jumanji/blob/main/CONTRIBUTING.md) or just

[star](https://github.com/instadeepai/jumanji) 🌟 to stay up to date with the latest developments!

### Goals 🚀

1. Provide a simple, well-tested API for JAX-based environments.

2. Make research in RL more accessible.

3. Facilitate the research on RL for problems in the industry and help close the gap between

research and industrial applications.

4. Provide environments whose difficulty can be scaled to be arbitrarily hard.

### Overview 🦜

- 🥑 **Environment API**: core abstractions for JAX-based environments.

- 🕹️ **Environment Suite**: a collection of RL environments ranging from simple games to NP-hard

combinatorial problems.

- 🍬 **Wrappers**: easily connect to your favourite RL frameworks and libraries such as

[Acme](https://github.com/deepmind/acme),

[Stable Baselines3](https://github.com/DLR-RM/stable-baselines3),

[RLlib](https://docs.ray.io/en/latest/rllib/index.html), [OpenAI Gym](https://github.com/openai/gym)

and [DeepMind-Env](https://github.com/deepmind/dm_env) through our `dm_env` and `gym` wrappers.

- 🎓 **Examples**: guides to facilitate Jumanji's adoption and highlight the added value of

JAX-based environments.

- 🏎️ **Training:** example agents that can be used as inspiration for the agents one may implement

in their research.

Installation 🎬


You can install the latest release of Jumanji from PyPI:

```bash

pip install -U jumanji

```

Alternatively, you can install the latest development version directly from GitHub:

```bash

pip install git+https://github.com/instadeepai/jumanji.git

```

Jumanji has been tested on Python 3.10, 3.11 and 3.12.

Note that because the installation of JAX differs depending on your hardware accelerator,

we advise users to explicitly install the correct JAX version (see the

[official installation guide](https://github.com/google/jax#installation)).

**Rendering:** Matplotlib is used for rendering all the environments. To visualize the environments

you will need a GUI backend. For example, on Linux, you can install Tk via:

`apt-get install python3-tk`, or using conda: `conda install tk`. Check out

[Matplotlib backends](https://matplotlib.org/stable/users/explain/backends.html) for a list of

backends you can use.

Quickstart ⚡


RL practitioners will find Jumanji's interface familiar as it combines the widely adopted

[OpenAI Gym](https://github.com/openai/gym) and

[DeepMind Environment](https://github.com/deepmind/dm_env) interfaces. From OpenAI Gym, we adopted

the idea of a `registry` and the `render` method, while our `TimeStep` structure is inspired by

DeepMind Environment.

### Basic Usage 🧑‍💻

```python

import jax

import jumanji

# Instantiate a Jumanji environment using the registry

env = jumanji.make('Snake-v1')

# Reset your (jit-able) environment

key = jax.random.PRNGKey(0)

state, timestep = jax.jit(env.reset)(key)

# (Optional) Render the env state

env.render(state)

# Interact with the (jit-able) environment

action = env.action_spec.generate_value()          # Action selection (dummy value here)

state, timestep = jax.jit(env.step)(state, action)   # Take a step and observe the next state and time step

```

- `state` represents the internal state of the environment: it contains all the information required

to take a step when executing an action. This should **not** be confused with the `observation`

contained in the `timestep`, which is the information perceived by the agent.

- `timestep` is a dataclass containing `step_type`, `reward`, `discount`, `observation` and

`extras`. This structure is similar to

[`dm_env.TimeStep`](https://github.com/deepmind/dm_env/blob/master/docs/index.md) except for the

`extras` field that was added to allow users to log environments metrics that are neither part of

the agent's observation nor part of the environment's internal state.

### Advanced Usage 🧑‍🔬

Being written in JAX, Jumanji's environments benefit from many of its features including

automatic vectorization/parallelization (`jax.vmap`, `jax.pmap`) and JIT-compilation (`jax.jit`),

which can be composed arbitrarily.

We provide an example of a more advanced usage in the

[advanced usage guide](https://instadeepai.github.io/jumanji/guides/advanced_usage/).

### Registry and Versioning 📖

Like OpenAI Gym, Jumanji keeps a strict versioning of its environments for reproducibility reasons.

We maintain a registry of standard environments with their configuration.

For each environment, a version suffix is appended, e.g. `Snake-v1`.

When changes are made to environments that might impact learning results,

the version number is incremented by one to prevent potential confusion.

For a full list of registered versions of each environment, check out

[the documentation](https://instadeepai.github.io/jumanji/environments/tsp/).

Training 🏎️


To showcase how to train RL agents on Jumanji environments, we provide a random agent and a vanilla

actor-critic (A2C) agent. These agents can be found in

[jumanji/training/](https://github.com/instadeepai/jumanji/tree/main/jumanji/training/).

Because the environment framework in Jumanji is so flexible, it allows pretty much any problem to

be implemented as a Jumanji environment, giving rise to very diverse observations. For this reason,

environment-specific networks are required to capture the symmetries of each environment.

Alongside the A2C agent implementation, we provide examples of such environment-specific

actor-critic networks in

[jumanji/training/networks](https://github.com/instadeepai/jumanji/tree/main/jumanji/training/networks/).

> ⚠️ The example agents in `jumanji/training` are **only** meant to serve as inspiration for how one

> can implement an agent. Jumanji is first and foremost a library of environments - as such, the

> agents and networks will **not** be maintained to a production standard.

For more information on how to use the example agents, see the

[training guide](https://instadeepai.github.io/jumanji/guides/training/).
