Uses pure python method for object dtype, and numpy method for all other dtypes. Parameters ---------- values : ndarray Values to check for unknowns. return_inverse : bool, default=False If True, also return the indices of the unique values. return_counts : bool, default=False If True, also return the number of times each unique item appears in values. Returns ------- unique : ndarray The sorted unique values. unique_inverse : ndarray The indices to reconstruct the original array from the unique array. Only provided if `return_inverse` is True. unique_counts : ndarray The number of times each of the unique values comes up in the original array. Only provided if `return_counts` is True. r )dtypeobject_unique_python _unique_np)valuesrrrX/home/air/segue/gemini/backup/venv/lib/python3.10/site-packages/sklearn/utils/_encode.py_uniques rc Cst|\}}d\}}|r|r||\}}}}n|r"||\}}n|r,||\}}n||}|jrgt|drgt||j|d}|d|d}|rR||||k<|rg| ||d||<|d|d}|f} |rq| |f7} |rx| |f7} t | dkr| dS| S)zHelper function to find unique values for numpy arrays that correctly accounts for nans.
