Sklearn tests: Errors and Failures under Intel Python distribution 3.5.3

Hello folks,

After googling for a while, an alternative way for running sklearn suite test came to light. It is
via the shell command "nosetests  --exe sklearn"

Shown below are some errors and failures obtained when executing it under
   Python version 3.5.3 |Intel Corporation| (default, May 18 2017,
   22:17:21) [GCC 4 .8.2 20140120 (Red Hat 4.8.2-15)]

Salut,

Sergio
