Conda Kivy Windows

[Piet Jones]

Hi,

Kivy is amazing! I have written a kivy application on my linux distribution
successfully. I now want to compile this into a kivy application that can
work on windows. Following the instruction on kivy on how to package a
script on windows, mentions I need to do this all on windows with
pyinstaller.

So I have a Anaconda installation of Python on windows but for some reason
I am struggling to get kivy to work on windows. I have tried the following.

Following the installation instructions on
http://kivy.org/docs/installation/installation-windows.html
This however gives me a completely seperate python installation without the
libraries necessary to run my script ( numpy, scipy, pandas, matplotlib). I
then tried to install these, but I struggle to install scipy.

I also tried to install kivy in my Anaconda python installtion (which has
all the packages I need except kivy) using pip install kivy. This created
issues with compilers, Visual Studio 2008 problems. After installing Visual
Studio 2008, as suggested by the warning comment in this post
http://stackoverflow.com/questions/2817869/error-unable-to-find-vcvarsall-bat/10558328#10558328

I get from pip install kivy, (last part of pip.log):

The kivy documentation suggests that this might be a bad idea as the
instructions for compiling a package requires running kivy.bat, which does
some environmental prep and naturally uses the new python installation and
not my Anaconda installation. Is this assumption correct? What is the best
way around this? Is there a easier way to get kivy installed in an already
existing python installation, or is that a fool's errand? (Sorry have not
used windows is some time, and I defininately do not code on windows).

Any help/advice would be appreciated.

Kind Regards,
Piet Jones

Found a work around, which is not ideal but it works, basically it involves recreating everything in the kivy based python environment.

Double click kivy.bat to create the environment. Then in that console do the following:
-Run the script from http://effbot.org/zone/python-register.htm, to add the current python to the registry.
-pip install numpy
-Download the 32bit version of scipy windows exe installer from: http://sourceforge.net/projects/scipy/files/scipy/0.14.0/
  - when installing make sure that the kivy python is selected
-Similarly for matplotlib: http://matplotlib.org/downloads.html
-pip install pandas
-pip install pyside

Had to use the 'Qt4Agg' backend for matplotlib plots to show by adding to my app script, at the top:

import matplotlib
matplotlib.use('Qt4Agg')

Then for pyinstaller, I had to add 'scipy.special._ufuncs_cxx' to the hiddenimports list in the spec file that was generated for my app.
