The mean() method computes the arithmetic mean of a given set of numbers along the specified axis. The mean() method computes the arithmetic mean of a given set of numbers along the specified axis. import numpy as np # create an array array1 = np.array([
Previous: Write a NumPy program to create an array of 4,5 shape and to reverse the rows of the said array. After reversing 1st row will be 4th and 4th will be 1st, 2nd row will be 3rd row and 3rd row will be 2nd row. <!--Next: NumPy Random Exercises Home.--> Next:...
Parameters:a : array_like Array containing numbers whose mean is desired. If a is not an array, a conversion is attempted.axis : None or int or tuple of ints, optional Axis or axes along which the means are computed. The default is to compute the mean of the flattened array.New in ...

When I try to compute the weighted geometric mean of an array that includes 0, and that element is given a weight of 0, I'm getting a RuntimeWarning, and a nan result. This isn't the case when the weight is just slightly larger than zero. Drilling this down, I reached np.multiply...
