Attributes

__pybind11_module_local_v4_gcc_libstdcpp_cxxabi1014__

__class__

alias of pybind11_builtins.pybind11_type

__delattr__(name, /)

Implement delattr(self, name).

__dir__()

Default dir() implementation.

__eq__(value, /)

Return self==value.

__format__(format_spec, /)

Default object formatter.

__ge__(value, /)

Return self>=value.

__getattribute__(name, /)

Return getattr(self, name).

__gt__(value, /)

Return self>value.

__hash__()

Return hash(self).

__init__(self: openvino._pyopenvino.FrontEnd, other: openvino._pyopenvino.FrontEnd) → None

__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)

__pybind11_module_local_v4_gcc_libstdcpp_cxxabi1014__ = <capsule object NULL>

__reduce__()

Helper for pickle.

__reduce_ex__(protocol, /)

Helper for pickle.

__repr__(self: openvino._pyopenvino.FrontEnd) → 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).

add_extension(*args, **kwargs)

Overloaded function.

1. add_extension(self: openvino._pyopenvino.FrontEnd, arg0: openvino._pyopenvino.Extension) -> None

   Add extension defined by an object inheriting from Extension used in order to extend capabilities of Frontend.

   param extension

   Provided extension object.

   type extension

   Extension

2. add_extension(self: openvino._pyopenvino.FrontEnd, arg0: List[openvino._pyopenvino.Extension]) -> None

   Add extensions defined by objects inheriting from Extension used in order to extend capabilities of Frontend.

   param extension

   Provided extension objects.

   type extension

   List[Extension]

3. add_extension(self: openvino._pyopenvino.FrontEnd, arg0: object) -> None

   Add extension defined in external library indicated by a extension_path used in order to extend capabilities of Frontend.

   param extension_path

   A path to extension.

   type extension_path

   str, Path

convert(*args, **kwargs)

Overloaded function.

1. convert(self: openvino._pyopenvino.FrontEnd, model: ov::frontend::InputModel) -> openvino._pyopenvino.Model

   Completely convert and normalize entire function, throws if it is not possible.

   param model

   Input model.

   type model

   openvino.frontend.InputModel

   return

   Fully converted OpenVINO Model.

   rtype

   openvino.runtime.Model

2. convert(self: openvino._pyopenvino.FrontEnd, model: openvino._pyopenvino.Model) -> None

   Completely convert the remaining, not converted part of a function.

   param model

   Partially converted OpenVINO model.

   type model

   openvino.frontend.Model

   return

   Fully converted OpenVINO Model.

   rtype

   openvino.runtime.Model

convert_partially(self: openvino._pyopenvino.FrontEnd, model: ov::frontend::InputModel) → openvino._pyopenvino.Model

Convert only those parts of the model that can be converted leaving others as-is. Converted parts are not normalized by additional transformations; normalize function or another form of convert function should be called to finalize the conversion process.

:param model : Input model. :type model: openvino.frontend.InputModel :return: Partially converted OpenVINO Model. :rtype: openvino.runtime.Model

decode(self: openvino._pyopenvino.FrontEnd, model: ov::frontend::InputModel) → openvino._pyopenvino.Model

Convert operations with one-to-one mapping with decoding nodes. Each decoding node is an nGraph node representing a single FW operation node with all attributes represented in FW-independent way.

:param model : Input model. :type model: openvino.frontend.InputModel :return: OpenVINO Model after decoding. :rtype: openvino.runtime.Model

get_name(self: openvino._pyopenvino.FrontEnd) → str

Gets name of this FrontEnd. Can be used by clients if frontend is selected automatically by FrontEndManager::load_by_model.

Returns

Current frontend name. Returns empty string if not implemented.

Return type

str

load(self: openvino._pyopenvino.FrontEnd, path: object, enable_mmap: bool = True) → ov::frontend::InputModel

Loads an input model.

Parameters

• path (Any) – Object describing the model. It can be path to model file.

• enable_mmap (boolean) – Use mmap feature to map memory of a model’s weights instead of reading directly. Optional. The default value is true.

Returns

Loaded input model.

Return type

openvino.frontend.InputModel

normalize(self: openvino._pyopenvino.FrontEnd, model: openvino._pyopenvino.Model) → None

Runs normalization passes on function that was loaded with partial conversion.

:param model : Partially converted OpenVINO model. :type model: openvino.runtime.Model

supported(self: openvino._pyopenvino.FrontEnd, model: object) → bool

Checks if model type is supported.

Parameters

model (Any) – Object describing the model. It can be path to model file.

Returns

True if model type is supported, otherwise False.

Return type

bool
