Parameters ---------- ar : ndarray, shape (M, N) The input array. Returns ------- ar_out : ndarray, shape (P, N) A copy of the input array with repeated rows removed. Raises ------ ValueError : if `ar` is not two-dimensional. Notes ----- The function will generate a copy of `ar` if it is not C-contiguous, which will negatively affect performance for large input arrays. Examples -------- >>> ar = np.array([[1, 0, 1], ... [0, 1, 0], ... [1, 0, 1]], np.uint8) >>> unique_rows(ar) array([[0, 1, 0], [1, 0, 1]], dtype=uint8) z2unique_rows() only makes sense for 2D arrays, got z|ST) return_index)ndim ValueErrornpascontiguousarrayviewitemsizeshapeunique)ar ar_row_view_unique_row_indicesar_outs R/var/www/html/test/engine/venv/lib/python3.12/site-packages/skimage/util/unique.py unique_rowsrsF ww!| CBGG9 M    b !B''Br{{RXXa[89:;KIIkEA " #F M)numpyr rrrrs /r
