problem about using matplotlib in django

[Ahmet Temiz]

Hi,

In django I tried to use matplotlib and 

I run into this exception

...

  icon_img = Tk.PhotoImage(file=icon_fname)

  File "/usr/lib/python3.5/tkinter/__init__.py", line 3397, in __init__

    Image.__init__(self, 'photo', name, cnf, master, **kw)

  File "/usr/lib/python3.5/tkinter/__init__.py", line 3353, in __init__

    self.tk.call(('image', 'create', imgtype, name,) + options)

RuntimeError: main thread is not in main loop

How can I solve it?

regards
