When launching python scripts via a Jobs / Uproc / Interpreter, the python script output is not displayed on the Jobs Report / Uproc Job Log until the python script has finished its execution.
Any Scheduler / Environment using python scripts
Expected behavior, by default python buffers stdout and stderr streams until the end of the execution.
The option -u will allow to have the expected behavior:
-u : force the stdout and stderr streams to be unbuffered;
this option has no effect on stdin; also PYTHONUNBUFFERED=x
In order to be able to have the Job Log / Report updated in real-time while the python script is running, you need to add the option -u Invoke the python script via python -u yourscript.py
For example, this is the example of UC_EXT_INTERPRETERS_WINDOWS set on client 0 for Automic Workload Automation:
Please note that python.exe folder location SHOULD be available on the Windows PATH variable.
The same for Unix/Linux on UC_EXT_INTERPRETERS_UNIX
