python export example doesn't work

[aaronmarkham]

I tried a couple of variations.
It seems like mms.export_model still exists, but I would have thought this would have been changed to be like dms instead of mms. But even the original example still doesn't work.

>>> import mxnet as mx
>>> from dms.export_model import export_serving
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named dms.export_model
>>> from mms.export_model import export_serving
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name export_serving
>>>

from dms.export_model import export_serving should work. Try pip uninstall first and then install.

This and few other change are suggested here.
