Divide by zero warning

Code: Select all
/python2.7/site-packages/Orange/regression/lasso.py:253: RuntimeWarning: divide by zero encountered in divide
  coefficients /= sigma_x

or
Code: Select all
.bin/lib/python2.7/site-packages/Orange/regression/pls.py:439: RuntimeWarning: invalid value encountered in subtract
  xc = (ins - self.mu_x)

This is the error I am getting, particularly when running regression algorithms. Can somebody say why?
