System Requirements

To find details of the hardware and software configurations required for installation of IBM® Decision Optimization for Data Science Experience refer to the system requirements page.

Installation

Note: By default, the DSX Local installer also installs Decision Optimization for Data Science Experience Community Edition. The engines included in this default installation are limited to solving problems of a certain size. To use the full capacity Decision Optimization engines and solve larger problems, you need to install an add-on. See Decision Optimization for Data Science Experience for pricing.

To install Data Science Experience follow the detailed step-by-step installation instructions provided for DSX Local.

Select the appropriate version of the Decision Optimization add-on, according to your installed version of DSX Local, as shown in the following table.

Table 1. Compatible versions
DSX Local Version Decision Optimization for Data Science Experience Installer
DSX Local V1.2 Fix Pack 3 and later Decision Optimization V1.0.0.1 from Fix Central
DSX Local V1.2 and earlier Decision Optimization V1.0
To install the Decision Optimization full capacity add-on on top of an existing installation of DSX Local:
  • Login as root on the master node of DSX Local installation
  • Download the installation package TAR file into any directory
  • Run:
    tar xzvf <add-on-installer>.tar.gz
    cd dods_dsx_addon
     ./install.sh
The script will install the add-on on top of the existing DSX Local installation. The installation log file will be saved as dods_dsx_addon_install.log in the current directory.

To uninstall the add-on, run ./uninstall.sh from the same directory.

Python version

The Decision Optimization for Data Science Experience environment currently supports Python V2.7.

Problem size

As a DSX Local user, you have free access to the Community Edition of the Decision Optimization engines. The Community Edition is limited to 1000 constraints and variables, and a search space of 1000 X 1000 for constraint programming problem. You can run optimization models that don't exceed this size without any additional configuration. To solve larger problems, install the Decision Optimization full capacity add-on as described above.

Modeling Assistant version

The Modeling Assistant is currently in Beta version and supports scheduling and resource allocation problems.
