How

Answer 1

I faced the same problem on a script of my own and found that when adding the output from Ross' answer the script would actually run.

It appears that for some reason that redirecting output fixes the problem. Since I'm not interested in writing the output to disk I've instead written it to /dev/null (or the platform equivalent) with:

if ( sys.platform == 'win32' and sys.executable.split( '\\' )[-1] == 'pythonw.exe'):
    sys.stdout = open(os.devnull, 'w')
    sys.stderr = open(os.devnull, 'w')

The if statement ensures it only happens when the script is launched from pythonw.exe. I'm not sure if it is related but it was important to do this before other imports (including e.g. import logging).
