Nov 02, 2012 · df.to_numpy() is better than df.values, here's why. * It's time to deprecate your usage of values and as_matrix(). pandas v0.24.0 introduced two new methods for obtaining NumPy arrays from pandas objects: to_numpy(), which is defined on Index, Series, and DataFrame objects, and; array, which is defined on Index and Series objects only.

01.01.2000 · For extension types, to_numpy () may require copying data and coercing the result to a NumPy type (possibly object), which may be expensive. When you need a no-copy reference to the underlying data, Series.array should be used instead. This table lays out the different dtypes and default return types of to_numpy () for various dtypes within pandas.
