ak._v2.ak_from_numpy.from_numpy(array, regulararray=False, recordarray=True, highlevel=True, behavior=None)
  • array (np.ndarray) – The NumPy array to convert into an Awkward Array. This array can be a np.ma.MaskedArray.

  • regulararray (bool) – If True and the array is multidimensional, the dimensions are represented by nested ak.layout.RegularArray nodes; if False and the array is multidimensional, the dimensions are represented by a multivalued ak.layout.NumpyArray.shape. If the array is one-dimensional, this has no effect.

  • recordarray (bool) – If True and the array is a NumPy structured array (dtype.names is not None), the fields are represented by an ak.layout.RecordArray; if False and the array is a structured array, the structure is left in the ak.layout.NumpyArray format, which some functions do not recognize.

  • highlevel (bool) – If True, return an ak.Array; otherwise, return a low-level ak.layout.Content subclass.

  • behavior (None or dict) – Custom ak.behavior for the output array, if high-level.

Converts a NumPy array into an Awkward Array.

The resulting layout can only involve the following ak.layout.Content types:

  • ak.layout.NumpyArray

  • ak.layout.ByteMaskedArray or ak.layout.UnmaskedArray if the array is an np.ma.MaskedArray.

  • ak.layout.RegularArray if regulararray=True.

  • ak.layout.RecordArray if recordarray=True.
