a = np.array(...): Create a NumPy array 'a' containing the given integer values. np.unique(a, return_counts=True): Find the unique elements in the array 'a' and their counts using the np.unique function. The return_counts parameter is set to True, so the function returns two array...
In this Python blog, I will explainhow to get unique values in an array using the NumPy unique function in Python. I will explain different use cases for the NumPy unique function likenp.uniquewithout sorting, NumPy unique with tolerance, etc. To get unique values in an array, we can use...
The number of times each of the unique values comes up in the original array. Only provided ifreturn_countsis True. New in version 1.9.0. See also numpy.lib.arraysetops Module with a number of other functions for performing set operations on arrays. Notes When an axis is specified the su...

A test inunyt, fornp.unique_values, was written within the assumption that the outputs are expected to be strictly equal, but lately,it hasn't been the case. Was this assumption incorrect, or is this a regression in numpy ? I can reproduce the error without unyt, so I know it's not...
