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#

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.
