RuntimeWarning: to-Python converter for boost::shared_ptr<caffe::Net<float> > already registered; second conversion method ignored.

When I try to test python caffe by import caffe I get these warnings:

/home/user/Downloads/caffe/python/caffe/pycaffe.py:13: RuntimeWarning: to-Python converter for boost::shared_ptr<caffe::Net<float> > already registered; second conversion method ignored.
  from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \

These warnings are harmless and due to differences in boost versions. It would be nice to do away with them. See #3866 and #3575 for more detail.
