c:\Users\chc\Documents\Python\Repos\crikit2\crikit\preprocess\algorithms\abstract_als.py:82: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use arr[tuple(seq)] instead of arr[seq]. In the future this will be interpreted as an array index, arr[np.array(seq)], which will result either in an error or a different result.
