Agents

In TF-Agents, the core elements of RL algorithms are implemented as Agents. An agent encompasses two main responsibilities: defining a Policy to interact with the Environment, and how to learn/train that Policy from collected experience.

Currently the following algorithms are available under TF-Agents:

Tutorials

See tf_agents/colabs/ for tutorials on the major components provided.

Examples

End-to-end examples training agents can be found under each agent directory. e.g.:

Installation

To install the latest version, use nightly builds of TF-Agents under the pip package tf-agents-nightly, which requires you install on one of tf-nightly and tf-nightly-gpu and also tfp-nightly. Nightly builds include newer features, but may be less stable than the versioned releases.

To install the nightly build version, run the following:

# Installing with the `--upgrade` flag ensures you'll get the latest version.
pip install --user --upgrade tf-agents-nightly  # depends on tf-nightly

If you clone the repository you will still need a tf-nightly installation. You can then run pip install -e .[tests] from the agents directory to get dependencies to run tests.
