create_model_proto()

audonnx.testing.create_model_proto(shapes, *, dtype=1, opset_version=14)

Create test ONNX proto object.

Creates an identity graph with input and output nodes of the given shapes. For each entry an input and output node will be created. -1, None or strings define a dynamic axis. Per node, one dynamic axis is allowed. The identity graph can be used as path argument of audonnx.Model.

Parameters

• shapes (Sequence[Sequence[int]]) – list with shapes defining the identical input and output nodes of the model graph

• dtype (int) – data type, see supported data types

• opset_version (int) – opset version

Return type

ModelProto

Returns

ONNX object
