however, when use 'idle (python 3.4 gui - 32 bit)', cannot use matplotlib.pyplot , numpy.

i managed solve problem of numpy module, couldn't matplotlib...

your error requires module dateutil seen in output.

just run in command line,pip install dateutil

or if doesn't work, pip install python-dateutil
