I'd be grateful for any help. The tkagg backend requires a compiled C extension (_tkagg) built when matplotlib is built. If Tkinter was not available at the time matplotlib was built, then that extension may not exist. If you can provide the output of a clean matplotlib build (i.e. remove the build directory first) that would be the best way to diagnose that problem. Alternatively, you can switch to one of the other backends (which do not require a C extension as a bridge between matplotlib and GUI framework), such as GtkAgg, Qt4Agg, WxAgg etc. See here to learn how to switch backends: http://matplotlib.sourceforge.net/faq/installing_faq.html#what-is-a-backend Mike -- Michael Droettboom Science Software Branch Space Telescope Science Institute Baltimore, Maryland, USA -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

Re: [Matplotlib-users] virtualenv installation: ImportError: No module named _tkagg
I don't know if this is the same issue that I had once, but I will just throw it out there. Once I compiled matplotlib myself before double-checking that I had all the needed development files and so the build process didn't produce all the files for tkagg and used GTKAgg instead. I had to get all the needed development packages and completely clean out my build directory and rebuild matplotlib before it would work properly.

Re: [Matplotlib-users] virtualenv installation: ImportError: No module named _tkagg
Thanks to both of you for your replies. I should have included the info that I've tried to build matplotlib using virtualenv with the --no-site-packages option. ... And in the meantime, I have an existing (and working) build, courtesy of the Ubuntu package manager. Seeing as the package manager version is working, I'm going to scrub everything that I currently have (including any build directories which have been created along the way) and start from scratch... I'll let you know if that works!!
