[Matplotlib-users] Matplotlib vers. 1.5.0 warnings

[Virgil S. <vs...@it...>]

I recently upgraded to vers. 1.5.0 and I am now getting some warning messages. 
For example:

D:\Python27\lib\site-packages\matplotlib\backend_managers.py:62: UserWarning: 
Treat the new Tool classes introduced in v1.5 as experimental for now, the API 
will likely change in version 2.1 and perhaps the rcParam as well
   'version 2.1 and perhaps the rcParam as well')
D:\Python27\lib\site-packages\matplotlib\backend_tools.py:78: UserWarning: Treat 
the new Tool classes introduced in v1.5 as experimental for now, the API will 
likely change in version 2.1, and some tools might change name
   'version 2.1, and some tools might change name')

How can I keep these messages from being displayed (at least temporarily)?
