Building Python Pylab/matplotlib Exe Using Pyinstaller

The following code runs fine and displays a simple pie chart when run as an interpreted python py program. A month ago, I used pyinstaller to create a stand-alone exe and that work

Solution 1:

Found the solution. Apparently there was a bug in the version of pyinstaller I had. Found this post on pyinstaller's site: http://www.pyinstaller.org/ticket/651

So I downloaded the latest pyinstaller and I can build an exe of my piechart python program again!
