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
