Find unique rows in numpy.array

Question

I need to find unique rows in a numpy.array.

For example:

>>> a # I have
array([[1, 1, 1, 0, 0, 0],
       [0, 1, 1, 1, 0, 0],
         


        

Answer 1

As of NumPy 1.13, one can simply choose the axis for selection of unique values in any N-dim array. To get unique rows, one can do:

unique_rows = np.unique(original_array, axis=0)
