Re: [Matplotlib-users] can't import pylab

[John S. <pra...@ho...>]

Anyone have any help to get pylab working? Should I reinstall? What method should I use?









I'm using Mac os 10.4.11. Python is included in mac os. Matplotlib I installed from a precompiled version.

I tried doing what you suggest, but it didn't work. I still can't import pylab. There's also a file called libfreetype.6.3.dylib there. I don't know if that helps.
