Ray should work with Python 2. 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 python-dev python-pip libboost-all-dev unzip nodejs npm # If you're using Anaconda, then python-dev and python-pip are unnecessary.
pip install numpy funcsigs colorama psutil redis
pip install --upgrade git+git://github.com/cloudpipe/cloudpickle.git@0d225a4695f1f65ae1cbb2e0bbc145e10167cce4 # We use the latest version of cloudpickle because it can serialize named tuples.
pip install --upgrade --verbose "git+git://github.com/ray-project/ray.git#egg=numbuf&subdirectory=numbuf"
Ray can be installed with pip as follows.
pip install --upgrade --verbose "git+git://github.com/ray-project/ray.git#egg=ray&subdirectory=lib/python"
Alternatively, Ray can be built from the repository as follows.
git clone https://github.com/ray-project/ray.git
cd lib/python
python setup.py install
To test if the installation was successful, try running some tests. This assumes that you've cloned the git repository.
python test/runtest.py
