Prefect Community

Hi there. I have a `ShellTask` that runs a python script. I am trying to get the logs to show in Prefect Cloud in real time. I am trying to use the <https://docs.python.org/3.7/using/cmdline.html#envvar-PYTHONUNBUFFERED|PYTHONUNBUFFERED> environment variable to force a to print output as it happens but it's not working. I also tried calling the script with the `-u` option. Any ideas?

Are you doing:
```ShellTask(..., return_all=True, stream_output=True)```
?

I am using `stream_output=True`. Will test the other one.

What does your Python script do? Just making sure your shell task is doing “python aaa.py”?

When you mean it doesn’t work, do you get all the logs at the end? or it’s not streamed in real time?
