Based on the difference between NUMPY.RANDOM.RANDN () and Rand ()

Below for you to share an article based on NUMPY.RANDOM.RANDN () and Rand () a detailed explanation, with a good reference value, I hope to be helpful to everyone. Come and see it together.

There are some commonly used functions for generating random numbers in numpy , and Randn () and Rand () belong to this.

Numpy.random.randn (D0, D1, ..., dn) returns one or more sample values from a standard normal distribution.

A random sample of Numpy.random.rand (D0, D1, ..., dn) is located in [0, 1].

Import NumPy as NP arr1 = NP.RANDOM.RANDN (2,4) print (arr1) print (' **************************************************** ') arr2 = Np.random.rand (2,4) print (ARR2)
