VisibleDeprecationWarning: boolean index did not match indexed array along dimension 1; dimension is 2 but corresponding boolean dimension is 1

Question

After an update of Macports, that I think updated numpy, I\'m getting the warning:

VisibleDeprecationWarning: boolean index did not match indexed array alon         


        

Answer 1

I started getting a similar error after going up to numpy 1.10.1. I think you can get rid of the warning just by wrapping the boolean array in a numpy.where().

inliers = n.size(pixels[n.where(distances <= self.dst)])

Since you're just taking the size, there's no need to use the pixels array, so this should work:

inliers = n.size(n.where(distances <= self.dst])[0])
