Example -

# Importing libraries
import theano
from theano.tensor.random.utils import RandomStream

# Creating object of RandomStream
randomstream = RandomStream(seed=234)

# Creating matrix of random numbers between 0 and 10 of size 2x2
random_numbers = randomstream.uniform(0, 10, size=(2,2))

# Creating function
fun = theano.function([], random_numbers)

# Calling function
fun()

Output -
array([[1.26723814, 9.70915966],
       [1.39890979, 8.87548254]])

In this way, we can generate random numbers in theano.
