[Numpy-discussion] multivariate_normal issue with 'size' argument

[Nicolas Rougier]

Works for me (numpy 1.7.1, osx 10.8.3):

>>> import numpy as np
>>> print np.random.multivariate_normal(mean=np.zeros(2), cov=np.eye(2), size=1)
[[-0.55854737 -1.82631485]]
>>> print np.random.multivariate_normal(mean=np.zeros(2), cov=np.eye(2), size=np.int64(1))
[[ 0.40274243 -0.33922682]]
