Prerequisites and Limitations

You must satisfy the prerequisites before you can configure and/or run the Python DOE technique.

This page discusses:

Prerequisites

  • Python DOE technique

    The following prerequisites must be installed on the machines hosting Isight, SEEStation, and SEE Server, as applicable.

    1. Python version 3.7 or later, and it must be in path.
    2. Py4j module version 0.10.9 or later.
    3. External Python libraries on which the user supplied Python routine depends, if any.
    4. Sometimes a Python executable is not named python. In such a case, edit isight.properties, station.properties, and/or acs.properties files, as applicable, in <Isight_install_directory>/config directory and set the value of property "fiper.algorithms.python.python_executable" to the name of the Python executable.

General Limitations

  • The Python DOE technique has certain limitations, as follows
    1. The Python DOE technique supports only (*.py) file. Files that have other Python extensions are not supported.
    2. Import/Export of technique configuration is not supported for the Python DOE technique.
    3. You cannot set a Python Routine in the Python DOE technique from Webtop.
    4. The Python DOE technique supports only factors that have Real and Integer data types; factors that have String or Boolean data types are not supported
    5. The Python DOE technique does not support factors that have discrete limits imposed on them
  • The Sobol sequence DOE technique has certain limitations, as follows:
    1. Inclusion of more than 2 corner points in Sobol Sequence technique is supported only for up to 17 factors. For 18 or more factors, a maximum of 2 corner points can be included - one representing lower bound values for all factors, and another representing upper bound values for all factors.
