为什么“ numpy.random.random（（a，b））”不起作用？

Question

I am trying to create a matrix that creates a matrix of size a*b.

numpy.random.random((2,3)) #this works and creates a matrix of size 2,3

But,

m = input("Enter M: ")
n = input("Enter N: ")
o = input("Enter O: ")

A = numpy.random.random((m,n))
B = numpy.random.random((n,o))

why doesnt this work??

Answer 1

The problem is that the type of m,n and o is str . You need to add int around input , as follows:

import numpy
m = int(input("Enter M: "))
n = int(input("Enter N: "))
o = int(input("Enter O: "))

A = numpy.random.random((m,n))
B = numpy.random.random((n,o))
