Ray must currently be built from source. We have tested Ray on Ubuntu 14.04.
git clone https://github.com/ray-project/ray.git
First install the dependencies. We currently do not support Python 3.
sudo apt-get update
sudo apt-get install -y git cmake build-essential autoconf curl libtool python-dev python-numpy python-pip libboost-all-dev unzip graphviz
sudo pip install ipython funcsigs subprocess32 protobuf colorama graphviz
sudo pip install --upgrade git+git://github.com/cloudpipe/cloudpickle.git@0d225a4695f1f65ae1cbb2e0bbc145e10167cce4 # We use the latest version of cloudpickle because it can serialize named tuples.
Then run the setup scripts.
cd ray
./setup.sh # Build all necessary third party libraries (e.g., gRPC and Apache Arrow). This may take about 10 minutes.
./build.sh # Build Ray.
source setup-env.sh # Add Ray to your Python path.
For convenience, you may also want to add the line source "$RAY_ROOT/setup-env.sh"
to the bottom of your ~/.bashrc
file manually, where
$RAY_ROOT
is the Ray directory (e.g., /home/ubuntu/ray
).
To test if the installation was successful, try running some tests.
python test/runtest.py # This tests basic functionality.
python test/array_test.py # This tests some array libraries.
