Acme is a library of reinforcement learning (RL) agents and agent building blocks. Acme strives to expose simple, efficient, and readable agents, that serve both as reference implementations of popular algorithms and as strong baselines, while still providing enough flexibility to do novel research. The design of Acme also attempts to provide multiple points of entry to the RL problem at differing levels of complexity.
If you just want to get started using Acme quickly, the main thing to know about
the library is that we expose a number of agent implementations and an
EnvironmentLoop
primitive that can be used as follows:
loop = acme.EnvironmentLoop(environment, agent)
loop.run()
This will run a simple loop in which the given agent interacts with its
environment and learns from this interaction. This assumes an agent
instance
(implementations of which you can find here) and an environment
instance which implements the Deepmind Environment API. Each
individual agent also includes a README.md
file describing the implementation
in more detail. Of course, these two lines of code definitely simplify the
picture. To actually get started, take a look at the detailed working code
examples found in our examples subdirectory which show how to instantiate a
few agents and environments. We also include a
quickstart notebook.
Acme also tries to maintain this level of simplicity while either diving deeper into the agent algorithms or by using them in more complicated settings. An overview of Acme along with more detailed descriptions of its underlying components can be found by referring to the documentation. And we also include a tutorial notebook which describes in more detail the underlying components behind a typical Acme agent and how these can be combined to form a novel implementation.
We have tested acme
on Python 3.6 & 3.7.
-
Optional: We strongly recommend using a Python virtual environment to manage your dependencies in order to avoid version conflicts:
python3 -m venv acme source acme/bin/activate pip install --upgrade pip setuptools
-
To install the core libraries (including Reverb, our storage backend):
pip install dm-acme pip install dm-acme[reverb]
-
To install dependencies for our JAX- or TensorFlow-based agents:
pip install dm-acme[tf] # and/or pip install dm-acme[jax]
-
Finally, to install a few example environments (including gym, dm_control, and bsuite):
pip install dm-acme[envs]
