deprecation warning in numpy

I have a script running scikit Naive Bayes classification, that I wrote on a linux machine. when I transport it to a windows machine, I get a deprecation warning:

DeprecationWarning: Implicitly casting between incompatible kinds...

in the linux version I have numpy version 1.6.1 and in windows numpy version is 1.7.1rc1.

It throws the warning when casting a list of floats to a 2d array. Should I ignore the warning? Does it have to do with the change in numpy version?

The casting seems to work ok in both machines...

Thanks

You should of course update your code so that the warning goes away. Maybe by explicitly creating a Numpy array from the list.

I suppose with casting you mean some automatic conversion like:

array([1., 2, 3]) * [3, 4, 5]

Responsible seems to be the following pull request, that was merged relatively recently. The best explanation is in file test_ufunc.py.
