This module is home to specific dtypes related functionality and their classes.
For more general information about dtypes, also see numpy.dtype and
Data type objects (dtype).
Similar to the builtin types module, this submodule defines types (classes)
that are not widely used directly.
在 NumPy 版本加入: 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.
