Finding indexes of matching rows in two numpy arrays -

this question has answer here:

how can find indexes of rows match between 2 numpy arrays. example:

x = np.array(([0,1],               [1,0],               [0,0])) y = np.array(([0,1],               [1,1],               [0,0]))

this should return:

matches = [0,2] # match @ row no 0 , 2

np.flatnonzero((x == y).all(1)) # array([0, 2])

or:

np.nonzero((x == y).all(1))[0]

or:

np.where((x == y).all(1))[0]
