_tkinter.TclError: couldn't connect to display "localhost:21.0"

Hi dear developer,

Thanks for the great tools. As I upgrated wgdi to 0.6.4, the error occured. I supposed it may due to that I use a remote sge server without the support of interactive backend. Could please give me some suggestions how to handle the problem? Many thanks!

You can try reinstalling the matplotlib package.
