MatplotlibDeprecationWarning - google colab

[vinaghost]

I use your repo on google colab

and got these message, is this normal ?

object_detection_eval.py:288: MatplotlibDeprecationWarning: 
The set_window_title function was deprecated in Matplotlib 3.4 and will be removed two minor releases later. Use `.FigureManagerBase.set_window_title` or GUI-specific methods instead.
  fig.canvas.set_window_title('AP ' + class_name)
object_detection_eval.py:452: MatplotlibDeprecationWarning:

  fig.canvas.set_window_title(window_title)

@vinaghost seems to be a matplotlib compatibility issue, and should be able to fix by changing

fig.canvas.set_window_title

to

fig.canvas.manager.set_window_title
