__class__#: alias of pybind11_type

__delattr__(name, /)#: Implement delattr(self, name).

__dir__()#: Default dir() implementation.

__eq__(self: openvino._pyopenvino.Type, arg0: openvino._pyopenvino.Type) → bool#

__format__(format_spec, /)#: Default object formatter.

__ge__(value, /)#: Return self>=value.

__getattribute__(name, /)#: Return getattr(self, name).

__gt__(value, /)#: Return self>value.

__hash__(self: openvino._pyopenvino.Type) → int#

__init__(self: openvino._pyopenvino.Type, dtype: object) → None#

Convert numpy dtype into OpenVINO type

Parameters:: dtype (numpy.dtype) – numpy dtype
Returns:: OpenVINO type object
Return type:: ov.Type

__init_subclass__()#

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

__le__(value, /)#: Return self<=value.

__lt__(value, /)#: Return self<value.

__ne__(value, /)#: Return self!=value.

__new__(**kwargs)#

__reduce__()#: Helper for pickle.

__reduce_ex__(protocol, /)#: Helper for pickle.

__repr__(self: openvino._pyopenvino.Type) → str#

__setattr__(name, value, /)#: Implement setattr(self, name, value).

__sizeof__()#: Size of object in memory, in bytes.

__str__()#: Return str(self).

__subclasshook__()#

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

bf16 = <Type: 'bfloat16'>#

property bitwidth#

boolean = <Type: 'char'>#

compatible(self: openvino._pyopenvino.Type, other: openvino._pyopenvino.Type) → bool#

Checks whether this element type is merge-compatible with other.

Parameters:: other (openvino.runtime.Type) – The element type to compare this element type to.
Returns:: True if element types are compatible, otherwise False.
Return type:: bool
