In numpy<2.0, np.array(x, copy=False) means "avoid a copy when possible"; in numpy>=2.0 the same call means "never copy, raise if one would be required" - a silent behavior change, not a removed symbol, so it doesn't fail until actually exercised on data that needs a copy. np.asarray(x) is numpy's documented migration-guide replacement that preserves the original <2.0 behavior exactly.
