- """
- This module is home to specific dtypes related functionality and their classes.
- For more general information about dtypes, also see `numpy.dtype` and
- :ref:`arrays.dtypes`.
- Similar to the builtin ``types`` module, this submodule defines types (classes)
- that are not widely used directly.
- .. versionadded:: NumPy 1.25
- The dtypes module is new in NumPy 1.25. Previously DType classes were
- only accessible indirectly.
- DType classes
- -------------
- The following are the classes of the corresponding NumPy dtype instances and
- NumPy scalar types. The classes can be used in ``isinstance`` checks and can
- also be instantiated or used directly. Direct use of these classes is not
- typical, since their scalar counterparts (e.g. ``np.float64``) or strings
- like ``"float64"`` can be used.
