Installation on Ubuntu¶
Ray should work with Python 2 and Python 3. We have tested Ray on Ubuntu 14.04 and Ubuntu 16.04.
You can install Ray as follows.
pip install ray
Building Ray from source¶
If you want to use the latest version of Ray, you can build it from source.
To build Ray, first install the following dependencies. We recommend using Anaconda.
sudo apt-get update sudo apt-get install -y cmake pkg-config build-essential autoconf curl libtool unzip python # we install python here because python2 is required to build the webui # 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. # If you are on Ubuntu 14.04, you need the following. pip install cmake pip install numpy cloudpickle funcsigs click colorama psutil redis flatbuffers cython
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 # Add --user if you see a permission denied error.
Test if the installation succeeded¶
To test if the installation was successful, try running some tests. This assumes that you’ve cloned the git repository.
Cleaning the source tree¶
The source tree can be cleaned by running
git clean -f -f -x -d
