cast_to_ndarray

pybear.base.cast_to_ndarray(X, copy_X=True)

Convert the container of X to numpy.ndarray.

Can take Python lists, tuples, and sets, numpy ndarrays and masked arrays, pandas dataframes and series, polars dataframes and series, and scipy sparse matrices and arrays. Any nan-like values are standardized to numpy.nan.

Parameters:

XXContainer of shape (n_samples, n_features) or (n_samples,)

The array-like data to be converted to ndarray.

copy_Xbool, default=True

Whether to copy X before casting to ndarray or perform the operations directly on the passed X.

Returns:

Xnumpy.ndarray

The original data converted to numpy.ndarray.
