I installed milk and imported in Ipyhton by import milk. It says the below system error.

In [1]: import milk

SystemError: initialization of _kmeans failed without raising an exception

I found milk will be helpful in case to do K means clustering with mahalanobis distance instead of euclidean distance. can you please tell me how to rectify this error.
