Retrieve position of elements with setting some criteria in numpy

Question

For the given 2d array of data, how to retrieve the position (index) of 7 and 11 in the bold. Because only they are the elements surrounded by same value in the neighbours

Answer 1

I have tested it and the following code works:

for i in range(1,np.shape(data)[0]-1):
    for j in range(1,np.shape(data)[1]-1):
        if np.all(data[i-1:i+2,j-1:j+2]==data[i,j]):
            print np.array([i,j], dtype=np.int64)
