GetDynamicInputShape

Function Usage

Obtains the pointer to a dynamic input shape based on the input index in the operator prototype definition.

Prototype

const Shape *GetDynamicInputShape(const size_t ir_index, const size_t relative_index) const

Parameters

Parameter	Input/Output	Description
ir_index	Input	Index of the dynamic input in the operator IR prototype definition, starting from 0.
relative_index	Input	Relative index after the input is instantiated. For example, if three inputs are instantiated for a dynamic input, the value range of relative_index is [0, 2].

Returns

Input shape pointer. If the ir_index or relative_index is invalid, a null pointer is returned.

For details about the definition of the shape type, see Shape.

Examples

ge::graphStatus InferFormatForXXX(InferFormatContext *context) {
  const auto shape= context->GetDynamicInputShape(1U, 0U); 
  GE_ASSERT_NOTNULL(shape);
  // ...
}
