TensorFlow Agents

Reinforcement Learning with TensorFlow

Agents makes designing, implementing and testing new RL algorithms easier, by providing well tested modular components that can be modified and extended. It enables fast code iteration, with good test integration and benchmarking.

To get started, we recommend checking out one of our tutorials.


TF-Agents publishes nightly and stable builds. For a list of releases read the Releases section. The commands below cover installing TF-Agents stable and nightly from pypi.org as well as from a GitHub clone.


Run the commands below to install the most recent stable release (0.5.0), which was tested with TensorFlow 2.2.x and Python3.

pip install --user tf-agents
pip install --user tensorflow==2.2.0

# To get the matching examples and colabs
git clone https://github.com/tensorflow/agents.git
cd agents
git checkout v0.5.0

If you want to use TF-Agents with TensorFlow 1.15 or 2.0, install version 0.3.0:

pip install tf-agents==0.3.0
# Newer versions of tensorflow-probability require newer versions of TensorFlow.
pip install tensorflow-probability==0.8.0


Nightly builds include newer features, but may be less stable than the versioned releases. The nightly build is pushed as tf-agents-nightly. We suggest installing nightly versions of TensorFlow (tf-nightly) and TensorFlow Probability (tfp-nightly) as those are the version TF-Agents nightly are tested against.

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
# `--force-reinstall helps guarantee the right version.
pip install --user --force-reinstall tf-nightly
pip install --user --force-reinstall tfp-nightly

From GitHub

After cloning the repository, the dependencies can be installed by running pip install -e .[tests]. TensorFlow needs to be installed independently: pip install --user tf-nightly.


We're eager to collaborate with you! See CONTRIBUTING.md for a guide on how to contribute. This project adheres to TensorFlow's code of conduct. By participating, you are expected to uphold this code.


TF Agents has stable and nightly releases. The nightly releases are often fine but can have issues due to upstream libraries being in flux. The table below lists the version(s) of TensorFlow tested with each TF Agents' release to help users that may be locked into a specific version of TensorFlow.

Release Branch / Tag TensorFlow Version
Nightly master tf-nightly
0.5.0 v0.5.0 2.2.0
0.4.0 v0.4.0 2.1.0
0.3.0 v0.3.0 1.15.0 and 2.0.0

Examples of installing nightly, most recent stable, and a specific version of TF-Agents:

# Stable
pip install tf-agents

# Nightly
pip install tf-agents-nightly

# Specific version
pip install tf-agents==0.3.0
