ak.from_arrow ------------- .. py:module: ak.from_arrow Defined in `awkward.operations.ak_from_arrow `__ on `line 16 `__. .. py:function:: ak.from_arrow(array, *, generate_bitmasks=False, highlevel=True, behavior=None, attrs=None) :param array: Apache Arrow array to convert into an Awkward Array. :type array: ``pyarrow.Array``, ``pyarrow.ChunkedArray``, ``pyarrow.RecordBatch``, or ``pyarrow.Table`` :param generate_bitmasks: If enabled and Arrow/Parquet does not have Awkward metadata, ``generate_bitmasks=True`` creates empty bitmasks for nullable types that don't have bitmasks in the Arrow/Parquet data, so that the Form (BitMaskedForm vs UnmaskedForm) is predictable. :type generate_bitmasks: bool :param highlevel: If True, return an :py:obj:`ak.Array`; otherwise, return a low-level :py:obj:`ak.contents.Content` subclass. :type highlevel: bool :param behavior: Custom :py:obj:`ak.behavior` for the output array, if high-level. :type behavior: None or dict :param attrs: Custom attributes for the output array, if high-level. :type attrs: None or dict Converts an Apache Arrow array into an Awkward Array. This function always preserves the values of a dataset; i.e. the Python objects returned by :py:obj:`ak.to_list` are identical to the Python objects returned by Arrow's ``to_pylist`` method. If :py:obj:`ak.to_arrow` was invoked with ``extensionarray=True``, this function also preserves the data type (high-level :py:obj:`ak.types.Type`, though not the low-level :py:obj:`ak.forms.Form`), even through Parquet, making Parquet a good way to save Awkward Arrays for later use.
