Application Programming Interface

SAInt-API is a powerful tool to automate the manual processes in the GUI. It gives access to multiple network and scenario data processing and execution functions. The API can be used with Python, C++, and other programming languages.

1. Requirement

1.1. Python

Python version: SAInt-API has been tested with multiple releases of Python. Python 3.9 and 3.10 are perfectly compatible. Python 3.11 and 3.12 may generate compatibility problems in conjunction with other packages or caused by unsolved bugs. We encourage our users to avoid the very latest release of Python.

Ctypes package: The ctypes package provides C-compatible data types and allows function calls from a dynamic link library (DLL). It can imported using from ctypes import * command.

Access API Functions: It is necessary to create a DLL object using mydll = cdll.LoadLibrary(path) command, where path is the directory of the SAInt API and DLL file. The SAInt-API functions can then be accessed as attributes of the DLL object.

If you are not able to load SAInt-API, try the following:

  1. Go to "Edit the system environment variables" by searching in the Windows start menu.

  2. On the System Properties window, click on the button Environment variables.

  3. Under user variables, select Path and click on Edit.

  4. On the Edit environment variable window, check if the SAInt directory is listed there; if not, click on New and select the path where SAInt is installed: "C:\Program Files\encoord\SAInt-v3", and click OK on both.

  5. Close the interface and re-open.

If the problem persists, please contact encoord support.

5. Exception logging mechanism

SAInt API provides the user with a logging option for debugging possible errors and addressing exceptions caused by the execution of Python code. The exception logging mechanism saves the exception log either in the default directory .\encoord\SAInt-v3\Logs or in a user-specified directory if a new system environment variable named SAIntExceptionLogPath is defined.
