If you need to run on a remote headless server, for instance, you can use the Agg backend. I see that you are doing that (with the matplotlib.use('Agg')) line, so I'm surprised why any Tcl-related message would be displayed at all.

[Matplotlib-users] TclError Couldn't Connect to display ":0.0"
When I try to save a fig to a file I get the error TclError Couldn't Connect to display ":0.0" I looked in the Maplotlib users manual (latest version pg 144-146) and tried the following with no luck.
