GetInputTensor

Function Usage

Obtains the pointer to an input tensor based on the operator input index. The input index refers to the actual index after operator instantiation, not the index in the prototype definition.

Prototype

const Tensor *GetInputTensor(const size_t index) const

Parameters

Parameter	Input/Output	Description
index	Input	Operator input index, starting from 0.

Returns

Pointer to the input tensor. If the input index is invalid, a null pointer is returned.

For details about the definition of the tensor type, see Tensor.

Examples

ge::graphStatus InferShapeForReshape(InferShapeContext *context) {
  const gert::Shape *x_shape = context->GetInputShape(0);        // Obtain the shape of input 0.
  const gert::Tensor *shape_tensor = context->GetInputTensor(1); // Obtain the data dependency of input tensor 1.
  gert::Shape *output_shape = context->GetOutputShape(0);
  if (x_shape == nullptr || shape_tensor == nullptr || output_shape == nullptr) {
    // Defensive programming. In an undesirable scenario, an error is printed and a failure message is returned.
    return ge::GRAPH_FAILED;
  }
  // ...
}
