Problems with cx freeze when using matplotlib and figure.

by: roadjunky, 9 years ago


New to Python and have a script that runs fine in the IDE and the cx freeze build is successful with no errors but when I go to run the exe output it does nothing with no errors (same from cmd prompt window).  Narrowed the strange behavior down to the first call to matplotlib figure initialization (i.e. skip the matplotlib calls and it runs).  Any suggestions?

plt.figure(figsize=(5,5), dpi=100)

or

fig = Figure(figsize=(5,5), dpi=100)

Either has same do nothing behavior.

Using python34, latest libs, latest cx freeze and windows 10.  Not sure where to start debuging from here.  Here is the setup.py


import cx_Freeze
import sys
import matplotlib

base = None

if sys.platform == 'win32':
    base = "Win32GUI"

packages = ["tkinter","matplotlib","matplotlib.pyplot"]
excludes = []
includes = [matplotlib.get_data_path()]

executables = [cx_Freeze.Executable("excersizeTracker_000.py", base=base)]

cx_Freeze.setup(
    name = "Excersize Tracker",
    options = {"build_exe": {"packages":packages, "include_files":includes}},
    version = "0.000",
    description = "excersize tracker",
    executables = executables
    )

Could you also post the graphing code and and required data? Best thing I can do is try to make it run myself.

Thanks for your response and time!  Below is only a snippet of the script arrived from when I was divide and conquering to find what cx freeze was having troubles with.  When I did output the build result to a file I saw two warnings but they are there even when the matplotlib stuff is not run or imported and the exe runs so I think they are not critical.  Installed and imported pywind32 but did not make a differnce

*** WARNING *** unable to create version resource
install pywin32 extensions first

C:Python34libsite-packagescx_Freezefreezer.py:590: UserWarning: Duplicate name: 'importlib/__init__.pyc'
  outFile.writestr(zinfo, data)

Again thanks for any input and the great site.   Until I feel more comfortable with Python (by going through the tutorials) it is still kind of a black box to me as is cx freeze.

Ah, you didn't tell me about the tk part. Yikes! I did convert a tkinter application that uses Matplotlib in the past, have you tried to emulate the code? Here's the link:

https://pythonprogramming.net/converting-tkinter-to-exe-with-cx-freeze/

edit:

Another thing:
from PyQt4 import QtGui, QtCore


Any reason for PyQt in this code? Get rid of that for sure, and any other modules you are not using.

Sorry! The tk part on its own seems to work but not when mixing with matplotlib. Your tutorial link is what I looked at before attempting a cx freeze build.  I tried to run that code but got an error (see below, maybe that is a clue to my orginal problem?).  The PyQt was there from the complete code where I think I'm using a calendar widgit and maybe a list widget.  If I remove all the unused libs from the code I posted it still has the "do nothing" result.  Just trying to start by getting past that them hopefully the other stuff will just work.  Thanks again!

Updated numpy lib and your example script runs (with syntax warnings).  cx freeze build completes but when trying to run the exe output it does the "do nothing" same as my code.

Should have spelled out I'm using
cx_Freeze-4.3.4-cp34-none-win_amd64.whl
matplotlib-1.5.0-cp34-none-win_amd64.whl
numpy-1.10.4+mkl-cp34-none-win_amd64.whl

Any known issue with this combination?

Not that I know of. I'll tinker a bit with it to see if I can figure it out when I get a chance.

Thanks, it is driving me a bit batty.  Maybe it is a windows environment issue?  Just surprised an exception is not thrown.

Moved on to using C++ instead of Python.  Trying to use Python scripting for a windows executable was a mistake.  Works in some cases but not always.  At least I learned a few things about Python in the process.
