After commenting out the first line of code, the result of the program is different.
I stepped in to debug(the program runs to line 30), and found that when it hit the code"from numpy.dual import inv as func" 
It seems to use different inv().

Please report the bug with sklearn and numpy. I assume that the import of sklearn has a side-effect on numpy.
