There are two simple ways to find the index of the largest value in a Numpy array.

The first way is to use the argmax(~) function of the Numpy array:

x = np.array([3,5,2,1])
x.argmax()
1

Here, 1 is returned because the largest value (i.e. 5) is located at index 1.

The second way is to use the argmax(~) static function of the Numpy module:

x = np.array([3,5,2,1])
np.argmax(x)
1
