[Matplotlib-users] Memory leak using matplotlib

[Pellegrini E. <eri...@ya...>]

Hi evebrybody,
   
  I started a discussion one week ago about a problem of memory leak using the following code:
   
  ********************************************************************************
  from Tkinter import *
  from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
  import pylab
   
  def display():
  mat = pylab.zeros((100,100))
  pylab.ioff()
  image = pylab.matshow(mat)
  pylab.ion()
  pylab.close()
  can = FigureCanvasTkAgg(image, master=frame)
  can.show()
  can.get_tk_widget().grid(row = 0,column = 0)
   
  root = Tk()
  frame = Frame(root)
  frame.grid(row = 0,column = 0)
  canvas = Canvas(frame, width = 240, height = 240, relief = "sunken", bg = "white") 
  canvas.grid()
  button = Button(root,text="DisplayMatrix",command = display)
  button.grid(row = 1,column = 0)
  *******************************************************************************
   
  up to now, I have not found any way to solve it and unfortunately the proposed hints did not solve the problem (gc_collect(), clf(), cla()). Is there something new about this ?
   
  thanks
   
  Eric
