sktime.utils.data_processing.from_2d_array_to_nested(X, index=None, columns=None, time_index=None, cells_as_numpy=False)[source]

Convert tabular pandas DataFrame with only primitives in cells into nested pandas DataFrame with a single column.

Parameters
  • X (pd.DataFrame) –

  • cells_as_numpy (bool, default = False) – If True, then nested cells contain NumPy array If False, then nested cells contain pandas Series

  • index (array-like, shape=[n_samples], optional (default = None)) – Sample (row) index of transformed DataFrame

  • time_index (array-like, shape=[n_obs], optional (default = None)) – Time series index of transformed DataFrame

Returns

Xt – Transformed DataFrame in nested format

Return type

pd.DataFrame
