Hi, Anything I can do to help get a binary installer for OSX? If I wanted to build one myself - is there a good place to start looking to understand the problems?

I highly recommend macports[1] as the method to install matplotlib, as I have never had issues. -Sterling [1] http://www.macports.org/install.php On Oct 2, 2013, at 7:39AM, pymilo wrote: > Hello everyone, > > I want to work whit matplotlib and I installed it using pip command. > Apparently the installation was successful and when I open ipython and > import matplotlib everything works well.

Re: [Matplotlib-users] Matplotlib installation with Python(x,y)
It looks like the PyQt4 installation in python(x,y) is somehow broken. If you just open up the python(x, y) interpreter and type >>> from PyQt4.QtGui import QFormLayout or >>> from PyQt4 import QtGui what happens? If that fails too, I'd say the bug is in python(x, y) (or however PyQt4 got installled there).
