pyinstaller .exe cannot find 'dateutil.tz.__init__.tz' - python-3.x

Question

This is my very first time creating an .exe (or any package at all). Although I successfully created an exe-file of the kivy-touchtracer demo, according to the kivy-manual. I used the same approach to create an .exe from my kivy-app. It suppose to be running only on windows (first milestone).The non-exe version runs as I wanted. I could manage to create an .exe file, but somehow it is not running.Basically the programm should collect some data, "calculate a bit around" the given data, create some plots (matplotlib) and create a report-pdf (reportlab).
I already tried:
copy dateutils from python/Lib/sitepackages/dateutil into the created dist directory. (It helped by reportlab)
modifying the 'from .tz import *' line in dateutil/tz/init to 'from tz import *' (removing the dot)
They appeared useless...
How could I run my exe? What did I miss? (Matplotlib is in the supported-package list of pyinstaller.)

Answer 1

I had the same problem (also on windows 7 and Python 3.4 and python-dateutil version 2.5). I did some reading e.g. at https://github.com/dateutil/dateutil/pull/202#issuecomment-192352290. Like you I tried to make some amendments to the dateutil package, but in the end I simply reverted the package to the previous version with pip i.e. 'pip install python-dateutil==2.4.2' and that resolved the issue for me.

Answer 2

I had similar problem. Since everything worked I found a workaround using:
import warnings
warnings.filterwarnings("ignore", category=UserWarning)
