Jake, I'm using 0.11
Another example is that this works: clf.fit([[0, 0], [1, 1]], [0, 1]) But this doesn't: clf.fit([[0, 0, 0], [1, 1, 1]], [0, 1]) I'm not sure whether this is related, but I installed Pyth yesterday.. http://pypi.python.org/pypi/pyth/ Zach On 18/07/2012 17:41, Jake Vanderplas wrote: > Zach, > For your second snippet, I get this output using the dev version of > scikit-learn: > > coef array [ 0.33333333 0.33333333 0.33333333] > length 3 > getting value 0: 0.333333333333 > getting value 1: 0.333333333333 > > What version of scikit-learn are you using?
