• Pyinstaller "Failed to execute script pyi_rth_pkgres" and missing packages

  11 septembre 2016, par gurnben

  This is my first time posting a question here as most of my questions have already been answered by someone else ! I am working on a GUI application in python and am attempting to use pyinstaller to package it into a single folder and .exe for easier portability. Currently, I am using windows 10 and anaconda3 to manage my python packages. The application relies on tkinter, pillow, numpy, scikit-learn, opencv, ffmpeg, and matplotlib. The application is formatted with a main GUI.py file that creates objects of a number of other files (many of which are stored in a subfolder as this GUI is replacing a command line utility that served the same purpose). The issue I am running into (as you can see in the title) is that the .exe is throwing the error block :

  Traceback (most recent call last) :
  File "site-packages\PyInstaller\loader\rthooks\pyi_rth_pkgres.py", line 11, in
  File "c :\users\gurnben\anaconda3\envs\opencv\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module
  exec(bytecode, module.dict)
  File "site-packages\setuptools-20.7.0-py3.5.egg\pkg_resources__init__.py", line 68, in
  File "site-packages\setuptools-20.7.0-py3.5.egg\pkg_resources\extern__init__.py", line 60, in load_module
  ImportError : The ’packaging’ package is required ; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.
  Failed to execute script pyi_rth_pkgres

  When I look at the warn.txt it gives a massive list of missing packages including parts of some packages that are actually in the single folder package.
  I have, however, successfully gotten it to recognize the dll files from opencv and it is not listed among the missing (nor is ffmpeg however I did not see any ffmpeg files in the folder). I had to pass in a custom path to get it to include the opencv files as they are not in anaconda at this time.

  Any hints or ideas for next troubleshooting steps ? I am overly greatful for all of the help you an offer and I can upload any code, files, etc. that would help you diagnose the issue. In the meantime I will continue searching for a solution myself !

• matplotlib "RuntimeError : No MovieWriters available" when ffmpeg is installed

  11 août 2014, par user1637894

  I’m using OSX Mavericks and the Enthought Canopy distribution of python. I’m trying to run any simple example script that uses matplotlib.animation to save an animation, but I always get the following error :

  Traceback (most recent call last):
  
  File "/Users/Sam/Google Drive/Spyder workspace/MiscScripts/animation.py", line 14, in <module>
  
      FFMpegWriter = manimation.writers['ffmpeg']
  
  File "/Users/Sam/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/animation.py", line 63, in __getitem__
  
      raise RuntimeError("No MovieWriters available!")
  
  RuntimeError: No MovieWriters available!
  
  </module>

  Ffmpeg is installed on my system : I can access it by typing ffmpeg into a new terminal. So I’m guessing matplotlib simply doesn’t know that ffmpeg is available because it is not in the python path. So I tried typing which ffmpeg into a new terminal window to find where ffmpeg was installed, then I added this string to my python path via sys.append('path_here'), but this didn’t help.
