non interactive runs keep crashing due to DISPLAY

#1

Hello,

I am trying to run a plotting script. I have my imports as such:
from matplotlib import interactive
interactive(False)
import matplotlib.pyplot as plt

But I am getting this error repeatedly:

    fig=figure(1,figsize=(8,6))
  File "/usr/lib/python2.6/dist-packages/matplotlib/pyplot.py", line 251, in
figure
    **kwargs)
  File
"/usr/lib/python2.6/dist-packages/matplotlib/backends/backend_tkagg.py",
line 90, in new_figure_manager
    window = Tk.Tk()
  File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1646, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
TclError: couldn't connect to display "localhost:10.0"

My $DISPLAY variable does change from time to time, but as I have it set to
interactive, why should this matter?

I wanted to explain a little further. I have it set to interactive(False)
sorry if there is confusion in my above statement.
The reason my DISPLAY variable changes is that I am running the scripts on a
remote machine and using ssh -X to login. So each time I log in, the DISPLAY
variable may change.

Are you trying to run your script without opening a gui window?

If yes, "interacitve" is not what you want.

Anyhow, I had similar experience that some Tk application failed to
open over ssh connection. And sometimes, -Y option helped. If -Y does
not help, see if other backends work.
