When I ran a matplotlib example code ,There always was an error " AttributeError: module 'matplotlib.cbook' has no attribute 'deprecated'".

And what makes you think this a P4D Issue? Just google for " AttributeError: module 'matplotlib.cbook' has no attribute 'deprecated'" and see possible solutions.

You need to call MaskFPUExceptions(True), before loading python or at least before loading Numpy. See the links below.

(* Mask FPU Excptions - Useful for importing SciPy and other Python libs
   See http://bugs.python.org/issue9980 and
   http://stackoverflow.com/questions/3933851/
 *)
  procedure MaskFPUExceptions(ExceptionsMasked : boolean;
  MatchPythonPrecision : Boolean = True);

However the specific issue may be related to having conflicting versions of matplotlib installed.
