Hey Manoj, I think that the following link can help you to solve your problem. http://scikit-learn.org/stable/developers/contributing.html#random-numbers Best, Chris On Sat, Mar 31, 2018 at 5:38 AM, Manoj Karthick <mkselvak@sfu.ca> wrote:

I am working on adding a new estimator to the scikit-learn library, but the make command always exits with the below error message:

AssertionError: Estimator XYZ should not change or mutate the parameter random_state from 0 to <mtrand.RandomState object at 0x1a25da9e10> during fit.

Can you help me understand what the issue is?

Error log:

self = <sklearn.utils._unittest_backport.TestCase testMethod=__init__> msg = ‘Estimator XYZ should not change or mutate the parameter random_state from 0 to <mtrand.RandomState object at 0x1a25da9e10> during fit.'

def fail(self, msg=None): """Fail immediately, with the given message."""> raise self.failureException(msg) E AssertionError: Estimator XYZ should not change or mutate the parameter random_state from 0 to <mtrand.RandomState object at 0x1a25da9e10> during fit.

msg = 'Estimator XYZ should not change or mutate the parameter random_state from 0 to <mtrand.RandomState object at 0x1a25da9e10> during fit.' self = <sklearn.utils._unittest_backport.TestCase testMethod=__init__>

Thanks in advance, Manoj Karthick Selva Kumar
