ak.contents.NumpyArray ---------------------- .. py:module: ak.contents.NumpyArray Defined in `awkward.contents.numpyarray `__ on `line 60 `__. .. py:class:: ak.contents.NumpyArray(self, data, *, parameters=None, backend=None) A NumpyArray describes 1-dimensional or rectilinear data using a NumPy ``np.ndarray``, a CuPy ``cp.ndarray``, etc., depending on the backend. This class is aware of the rectilinear array's ``shape`` and ``strides``, and allows for arbitrary ``strides``, such as Fortran-ordered data. However, many operations require C-contiguous data, so derivatives of Fortran-ordered arrays may not be Fortran-ordered. Only a subset of ``dtype`` values are allowed, and only for your system's native endianness: * ``bool``: boolean, like NumPy's ``np.bool_`` (considered distinct from integers) * ``int8``: signed 8-bit * ``uint8``: unsigned 8-bit * ``int16``: signed 16-bit * ``uint16``: unsigned 16-bit * ``int32``: signed 32-bit * ``uint32``: unsigned 32-bit * ``int64``: signed 64-bit * ``uint64``: unsigned 64-bit * ``float16``: floating point 16-bit, if your system's NumPy supports it * ``float32``: floating point 32-bit * ``float64``: floating point 64-bit * ``float128``: floating point 128-bit, if your system's NumPy supports it * ``complex64``: floating complex numbers composed of 32-bit real/imag parts * ``complex128``: floating complex numbers composed of 64-bit real/imag parts * ``complex256``: floating complex numbers composed of 128-bit real/imag parts, if your system's NumPy supports it * ``datetime64``: date/time, origin is midnight on January 1, 1970, in any units NumPy supports * ``timedelta64``: time difference, in any units NumPy supports If the ``shape`` is one-dimensional, a NumpyArray corresponds to an Apache Arrow `Primitive array `__. To illustrate how the constructor arguments are interpreted, the following is a simplified implementation of ``__init__``, ``__len__``, and ``__getitem__``: .. code-block:: python class NumpyArray(Content): def __init__(self, data): assert isinstance(data, numpy_like_array) assert data.dtype in allowed_dtypes self.data = data def __len__(self): return len(self.data) def
