This repository contains the code for the PyRoboLearn (PRL) framework: a Python framework for Robot Learning. This framework revolves mainly around 7 axes: simulators, worlds, robots, interfaces, learning tasks (= environment and policy), learning models, and learning algorithms.
Warning: The development of this framework is ongoing, and thus some substantial changes might occur. Sorry for the inconvenience.
The framework has been tested with Python 2.7, 3.5 and 3.6, on Ubuntu 16.04 and 18.04. The installation on other OS is experimental.
There are two ways to install the framework:
- using a virtual environment and pip
- using a Docker
1. First download the pip Python package manager and create a virtual environment for Python as described in the following link: https://packaging.python.org/guides/installing-using-pip-and-virtualenv/ On Ubuntu, you can install pip and virtualenv by typing in the terminal:
- In Python 2.7:
sudo apt install python-pip
sudo pip install virtualenv- In Python 3.5:
sudo apt install python3-pip
sudo pip install virtualenvYou can then create the virtual environment by typing:
virtualenv -p /usr/bin/python<version> <virtualenv_name>
# activate the virtual environment
source <virtualenv_name>/bin/activatewhere <version> is the python version you want to use (select between 2.7 or 3.5), and <virtualenv_name> is a name of your choice for the virtual environment. For instance, it can be py2.7 or py3.5.
To deactivate the virtual environment, just type:
deactivate- clone this repository and install the requirements by executing the
setup.py
In Python 2.7:
git clone https://github.com/robotlearn/pyrobolearn
cd pyrobolearn
pip install numpy cython
pip install http://github.com/cornellius-gp/gpytorch/archive/alpha.zip # this is for Python 2.7
pip install -e . # this will install pyrobolearn as well as the required packages (so no need for: pip install -r requirements.txt)In Python 3.5:
git clone https://github.com/robotlearn/pyrobolearn
cd pyrobolearn
pip install numpy cython
pip install gpytorch # this is for Python 3.5
pip install -e . # this will install pyrobolearn as well as the required packages (so no need for: pip install -r requirements.txt)Depending on your computer configuration and the python version you use, you might need to install also the following packages through apt-get:
sudo apt install python-tk # if python 2.7
sudo apt install python3-tk # if python 3.5At the moment the docker is a self contained Ubuntu image with all the libraries installed. When launched we have access to a Python3.6 interpreter and we can import pyrobolearn directly. In the future, ROS may be splitted in another container and linked to this one.
- Install Docker and nvidia-docker
sudo apt-get update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable # you should replace bionic by your version
sudo apt update
sudo apt install docker-ce
sudo systemctl status docker # check that docker is active- Build the image
docker build -t pyrobolearn .- Launch
You can now start the python interpreter with every library already installed
docker run -p 11311:11311 -v $PWD/dev:/pyrobolearn/dev/:rw -ti pyrobolearn python3To open an interactive terminal in the docker image use:
docker run -p 11311:11311 -v $PWD/dev:/pyrobolearn/dev/:rw -ti pyrobolearn /bin/bash4. nvidia-docker if the GPU is not recognized in the interpreter, you can install nvidia-docker
curl -sL https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -sL https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
sudo apt-get install nvidia-docker2
sudo pkill -SIGHUP dockerdAnd use:
nvidia-docker run -p 11311:11311 -v $PWD/dev:/pyrobolearn/dev/:rw -ti pyrobolearnNote that some interfaces (like game controllers, depth camera, etc) might not be available on other OS, however the main robotic framework should work.
- Windows: You will have to install first PyBullet and NLopt beforehand.
For nlopt, install first conda, then type:
conda install -c conda-forge nloptIf Pybullet doesn't install on Windows (using visual studio), you might have to copy rc.exe and rc.dll from
C:\Program Files (x86)\Windows Kits\10\bin\<xx.x.xxxx.x>\x64
to
C:\Program Files (x86)\Windows Kits\10\bin\x86
And add the last folder to the Windows environment path (Go to System Properties > Advanced > Environment Variables > Path > Edit).
Finally, remove the nlopt package from the requirements.txt. The rest of the installation should be straightforward.
2. Mac OSX: We managed to install the PyRoboLearn framework on MacOSX (Mojave) by following the procedures explained in the section "Virtualenv & Pip". You can replace the sudo apt install by brew install (after installing Homebrew).
Check the README.rst file in the examples folder.
PyRoboLearn is currently released under the GNU GPLv3 license.
For how to cite this repository, please refer to the CITATION.rst file.
If you use a specific learning model, algorithm, robot, controller, and so on, please cite the corresponding paper. The reference(s) can usually be found in the class documentation (at the end), and sometimes in the README file in the corresponding folder.
Currently, we mainly use the PyBullet simulator.

- Locomotion controllers were provided by Songyan Xin
- We thanks Daniele Bonatto for providing the Docker file, and test the installation on Windows.
