The Omnia installer is based on the Conda package manager.  It can be used with any Python executable, but the easiest way to get started is to download and install the Anaconda Python distribution. This also includes many useful Python packages such as NumPy, SciPy, Matplotlib, ipython, etc.  We recommend the Python 3.4 version, but any version will work.

Once you have Python and Conda installed, type the following command into a terminal window to install Omnia:

 conda install -c omnia
