I have a numpy array like so:

arr = np.array([[[0,0],[93]],[[2,8],[94]]])

I now want to define two variables a and b like so:

a = 2
b = 8

Now, I want to write a program that retrieves the value corresponding to [a,b] from the numpy array. In this case, the value would be 94.

How do I solve this? I am open to other ways of organizing my data as well (lists, dictionaries etc) as long as the solution is optimal. However, I want to preserve the current format of an entry in the array viz., ([inp,inp],[out])

So far, I have tried using np.where but it returns an empty array:

np.where(arr == [2,8])

>>> (array([], dtype=int64), array([], dtype=int64))
