This guide explains how to setup your Python Bridge to begin using with Saga. It includes information on prerequisites, installing Python, and installing the dependencies.

Getting Python Bridge

Currently the only way to get a copy of Python Bridge is by requesting it to the Saga Team, for this please talk with your Accenture consultant for assistance.

Installing Python

The current versions of Python Bridge where develop and test using Python 3.7.2, but any Python 3.7.x version will suffice. At the moment of writing this guide the released version of 3.7 is Python 3.7.7 which you can download from here https://www.python.org/downloads/release/python-377/, please remember to download the 64-bit version of Python, some libraries are no compatible with the 32-bit version and will not work.

Creating and Starting a Virtual Environment

Once Python 3.7.x is installed, and poses a copy of Python Bridge, proceed to access the Python Bridge folder via console. Once there we will create a python virtual environment using the following command

python -m venv venv

This will create a folder names venv in our Python Bridge folder, a self-contained directory tree that contains a Python installation for a particular version of Python, plus a number of additional packages.

To be able to use this environment, we need to execute the active script for this execute the command

For Linux

source venv/bin/activate

For Windows

venv\Scripts\activate

This will execute the virtual environment and your console should present the prefix 

(venv) C:\Python Bridge>

Installing Python Bridge Dependencies

Once in the virtual environment proceed to install the Python Bridge dependencies, all the dependencies should be listed in a file called requirements.txt inside the Python Bridge folder. Install the dependencies by executing the following command:

pip install -r requirements.txt

If for any reason this command doesn't work try

python -m pip install -r requirements.txt

Start Python Bridge Server

Finally to start the Python Bridge server
