Installation on Ubuntu

Ray should work with Python 2 and Python 3. We have tested Ray on Ubuntu 14.04 and Ubuntu 16.04.


To install Ray, first install the following dependencies. We recommend using Anaconda.

sudo apt-get update
sudo apt-get install -y cmake build-essential autoconf curl libtool libboost-all-dev unzip

# If you are not using Anaconda, you need the following.
sudo apt-get install python-dev  # For Python 2.
sudo apt-get install python3-dev  # For Python 3.

pip install numpy cloudpickle funcsigs colorama psutil redis flatbuffers

If you are using Anaconda, you may also need to run the following.

conda install libgcc

git clone
cd ray/python
