Python Matplotlib runtime error upon closing the console -

I'm trying to create a bar with matplotlib on dragon tkinter. Everything works fine when I get the message of the tanker (console), it gives me this message.

I turned off my console I have already closed my tanker window so I am not sure which process it is referring to "still running" when I choose to kill it then give me this error message: < P>

This only occurs when I have my matplotlib Code is embedded when I get up Mr. script I cast my matplotlib code, it does not give me now the message and work properly. My code is as follows:

import my script

  or Tnkinr imports as imported importer matplotlib matplotlib.use ( 'TkAgg' ) import numpy as np import Matplotlibkpyplot Plt Import Import as mlab the matlotlib.backends.backend_tkagg imports as matplotlib.mlab, in NavigationToolbar2TkAgg import matplotlib.backend_bases to key_press_handler import matplotlib.figure import datetime import import datetime datetime

 Problems Or what is happening  
 I am using Window 8 (64 bit) with Python 2.7.4, matplotlib 1.2.0 (64 beats) Python 2.7   
 
 
 You have running multiple GUI event loops (one of you TK, and a  plt  starts)  plt < For a way to properly embed / code> or  mlab  not import  Tk , see.  
 You need to change this line by default  
  fig = PLT.figger ()   
 to   
 Fig / Figure ()   
 and get rid of  plt  in your import.
