[SciPy-User] numpy.random.choice throws AttributeError when called with a list of objects.

The code below results in:
AttributeError: SgCoord instance has no attribute 'ndim'

Given that an example in the documentation operates on an array of strings,
I'd expect numpy.random.choice to work with an array of objects. Is this 
not the case?


import numpy as np

class SgCoord():
    "A 2D coordinate"
    def __init__(self, x = 0, y = 0):
        self.x = x
        self.y = y
if __name__ == '__main__':
    l = []
