But that matches your question?
If you use ``normal``, just set the size (i.e., shape).
Help on package numpy.random in numpy:
Return an array containing multivariate normally distributed random numbers
with specified mean and covariance.
multivariate_normal(mean, cov) -> random values
multivariate_normal(mean, cov, [m, n, ...]) -> random values
mean must be a 1 dimensional array. cov must be a square two dimensional
array with the same number of rows and columns as mean has elements.
The first form returns a single 1-D array containing a multivariate
The second form returns an array of shape (m, n, ..., cov.shape).
In this case, output[i,j,...,:] is a 1-D array containing a multivariate
Normal distribution (mean=loc, stdev=scale).
normal(loc=0.0, scale=1.0, size=None) -> random values
