Re: [Numpy-discussion] numpy.power -> numpy.random.choice Probabilities don't sum to 1

A simple fix would certainly by pass the check in random.choice, but I don't know how to get that. So let's focus on the summation. I believe you are hitting an instability in summing small numbers as a power to 10th order would produce. Here is an example: mymatrix =

[Numpy-discussion] numpy.power -> numpy.random.choice Probabilities don't sum to 1

Hi, I have a matrix whose entries I must raise to a certain power and then normalize by row. After I do that, when I pass some rows to numpy.random.choice, I get a ValueError: probabilities do not sum to 1. I understand that floating point is not perfect, and my matrix is so large that I
