Chapter 1: Installing Python, SAS SWAT, and CAS
There are three primary pieces of software that must be installed in order to use SAS Cloud Analytic Services (CAS) from Python:
● Python 2.7 if you use Python 2, or a minimum of Python 3.4 if you use Python 3
● the SAS SWAT Python package
● the CAS server
We cover the recommended ways to install each piece of software in this chapter.
Installing Python
The Python packages that are used to connect to CAS have a minimum requirement of Python 2.7. If you are using version 3 of Python, you need a minimum of Python 3.4. There are some significant differences between Python 2 and Python 3, which are only touched on in this book. We recommend that you conduct your own research about the two primary versions of Python and choose the version that is appropriate for your needs. If you are not familiar with Python or if you don’t have a version preference, we recommend that you use the most recent release of Python 3. If you have an installation of Python 2 that you are using for existing work, then you can continue to use it. The Python package that is used to connect to CAS is compatible with both Python 2 and Python 3.
If you plan to use Microsoft Windows as your client operating system, you might not have an existing Python installation. If you use the Linux operating system or the Macintosh operating system, you probably have a Python installation already. In either case, you might need to install some prerequisite packages. We recommend that you start with a Python distribution such as Anaconda from Continuum Analytics at www.continuum.io which contains all of the prerequisites.
The Anaconda Python distribution includes dozens of the most popular Python packages, which can be installed easily on Windows, Linux, and Macintosh platforms. It also enables you to install a complete Python installation at any location on your system, including your home directory, so that you don’t need administrator privileges. Even if you do have administrator privileges and you have an existing Python installation on the Linux or Macintosh platforms, installing Anaconda as a separate Python is a good idea in order to prevent any mishaps that might occur while installing packages in the existing Python installation.
After you have installed Python, the next step is to install the SWAT package.
Installing SAS SWAT
The SAS SWAT package is the Python package created by SAS which is used to СКАЧАТЬ
