实际案例

>>> np.repeat(3, 4)  
array([3, 3, 3, 3])
>>> x = np.array([[1,2],[3,4]])  
>>> np.repeat(x, 2)  
array([1, 1, 2, 2, 3, 3, 4, 4])
>>> np.repeat(x, 3, axis=1)  
array([[1, 1, 1, 2, 2, 2],
       [3, 3, 3, 4, 4, 4]])
>>> np.repeat(x, [1, 2], axis=0)  
array([[1, 2],
       [3, 4],
       [3, 4]])
