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 python-dev python-pip # If you're using Anaconda, then python-dev and python-pip are unnecessary.
pip install numpy cloudpickle funcsigs colorama psutil redis
If you are using Anaconda, you may also need to run the following.
conda install libgcc
Ray can be built from the repository as follows.
git clone https://github.com/ray-project/ray.git
cd ray/python
python setup.py install --user
To test if the installation was successful, try running some tests. This assumes that you've cloned the git repository.
python test/runtest.py
Ray's web UI requires Python 3. To enable the web UI to work, install these Python packages.
pip install aioredis asyncio websockets
Then install polymer, which also requires Node.js and Bower.
Once you've installed Polymer, run the following.
cd ray/webui
bower install
Then while Ray is running, you should be able to view the web UI at
http://localhost:8080
