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

The numpy_indexed package (disclaimer: I am its author) wraps the solution posted by Jaime in a nice and tested interface, plus many more features:

import numpy_indexed as npi
new_a = npi.unique(a)  # unique elements over axis=0 (rows) by default
