Re: [Matplotlib-users] Matplotlib, Tk, and multithreading

Hi Ben,

> Are you displaying the plots in the thread, or are you just saving the plots directly?  If you are saving them directly, then you can set your backend to be "Agg" and get rid of the Tkinter.Tk() call (and probably should get rid of the import as well).  That way, matplotlib won't load up any gui toolkits at all.

I'm saving the plots directly (plt.figure();plt.plot();plt.savefig();plt.close(fig)). I tried doing as you suggested [don't import Tk directly and change the backend to Agg] but it still crashes with the same TkAqua message. I don't explicitly import or use Tk anywhere in my code, so it seems that matplotlib is trying to load it anyway even when instructed to use a different backend.

I'm running Enthought Python 7.3-2 on Mac OS X 10.6.8. Note that this problem seems to be restricted to this particular operating system; when I run the code on CentOS, also using EPD 7.3-2, it does not crash.

Cheers,
Oliver
