__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).

_get_raw_address(self: openvino._pyopenvino.Model) → int

Add new Parameter nodes to the list.

Method doesn’t change or validate graph, it should be done manually.

property outputs

property parameters

Return the model parameters.

Returns

a list of model’s parameters.

Return type

List[op.Parameter]

remove_parameter(self: openvino._pyopenvino.Model, parameter: openvino._pyopenvino.op.Parameter) → None

Delete Parameter node from the list of parameters. Method will not delete node from graph. You need to replace Parameter with other operation manually.

Attention: Indexing of parameters can be changed.

Possible use of method is to replace input by variable. For it the following steps should be done: * Parameter node should be replaced by ReadValue * call remove_parameter(param) to remove input from the list * check if any parameter indexes are saved/used somewhere, update it for all inputs because indexes can be changed * call graph validation to check all changes

Parameters

parameter (op.Parameter) – Parameter node to delete.

remove_result(self: openvino._pyopenvino.Model, result: openvino._pyopenvino.op.Result) → None

Delete Result node from the list of results. Method will not delete node from graph.

Parameters

result (op.Result) – Result node to delete.

remove_sink(self: openvino._pyopenvino.Model, sink: object) → None

Delete sink node from the list of sinks. Method doesn’t delete node from graph.

Parameters

sink (openvino.runtime.Node) – Sink to delete.

remove_variable(self: openvino._pyopenvino.Model, variable: openvino._pyopenvino.op.util.Variable) → None

Delete variable from the list of variables. Method doesn’t delete nodes that used this variable from the graph.

Parameters

variable (op.util.Variable) – Variable to delete.

replace_parameter(self: openvino._pyopenvino.Model, parameter_index: int, parameter: openvino._pyopenvino.op.Parameter) → None

Replace the parameter_index parameter of the model with parameter

All users of the parameter_index parameter are redirected to parameter , and the parameter_index entry in the model parameter list is replaced with parameter

Parameters

• parameter_index (int) – The index of the parameter to replace.

• parameter (op.Parameter) – The parameter to substitute for the parameter_index parameter.

reshape(*args, **kwargs)

Overloaded function.

1. reshape(self: openvino._pyopenvino.Model, partial_shape: openvino._pyopenvino.PartialShape) -> None

   Reshape model input.

   GIL is released while running this function.

   param partial_shape

   New shape.

   type partial_shape

   openvino.runtime.PartialShape

   :return : void

2. reshape(self: openvino._pyopenvino.Model, partial_shape: list) -> None

   Reshape model input.

   GIL is released while running this function.

   param partial_shape

   New shape.

   type partial_shape

   list

   :return : void

3. reshape(self: openvino._pyopenvino.Model, partial_shape: tuple) -> None

   Reshape model input.

   GIL is released while running this function.

   param partial_shape

   New shape.

   type partial_shape

   tuple

   :return : void

4. reshape(self: openvino._pyopenvino.Model, partial_shape: str) -> None

   Reshape model input.

   GIL is released while running this function.

   param partial_shape

   New shape.

   type partial_shape

   str

   :return : void

5. reshape(self: openvino._pyopenvino.Model, partial_shapes: dict) -> None

Reshape model inputs.

The allowed types of keys in the partial_shapes dictionary are:

1. int, input index

2. str, input tensor name

3. openvino.runtime.Output

The allowed types of values in the partial_shapes are:

1. openvino.runtime.PartialShape

2. list consisting of dimensions

3. tuple consisting of dimensions

4. str, string representation of openvino.runtime.PartialShape

When list or tuple are used to describe dimensions, each dimension can be written in form:

1. non-negative int which means static value for the dimension

2. [min, max], dynamic dimension where min specifies lower bound and max specifies upper bound; the range includes both min and max; using -1 for min or max means no known bound

3. (min, max), the same as above

(4) -1 is a dynamic dimension without known bounds (4) openvino.runtime.Dimension (5) str using next syntax:

‘?’ - to define fully dynamic dimension ‘1’ - to define dimension which length is 1 ‘1..10’ - to define bounded dimension ‘..10’ or ‘1..’ to define dimension with only lower or only upper limit

Reshape model input.
