How do you get the count of the occurrence of each value in a numpy array?

Question(s):

We can use the numpy.bincount() function to count of the occurrence of each value in a numpy array

Following is an example code:

arr = numpy.array([1,8,8,0,2,0,2,0,5,4,9,1,8,5,3])
numpy.bincount(arr)

The argument passed to the numpy.bincount() should consist of positive integers (negative integers are invalid) or boolean.
