Function Usage

Sets the symbolic expression of the tensor shape. If it is not set, there is no symbolic information by default.

Prototype

uint32_t EsSetOriginSymbolShape(EsCTensorHolder *tensor, const char *const *shape, int64_t dim_num);

Parameters

Parameter	Input/Output	Description
tensor	Input	Pointer to the tensor holder.
shape	Input	Pointer to the symbolic shape string array.
dim_num	Input	Number of symbolic shape strings.

Returns

Parameter	Type	Description
-	uint32_t	0: success; non-zero value: failure

Constraints

None

Examples

/ 1. Create a graph builder (EsCGraphBuilder).
EsCGraphBuilder *builder = EsCreateGraphBuilder("graph_name");
// 2. Add a start node.
EsCTensorHolder *data0 = EsCreateInput(builder, 0); // Add input node 0. The default value is a [] scalar.
const char* input_shape[] = {"a", "b", "c", "d"};
// Compute the number of dimensions (dim_num).
int64_t dim_num = sizeof(input_shape) / sizeof(input_shape[0]); // The result is 4.
EsSetOriginSymbolShape(data0, input_shape, dim_num); //Set the symbolic shape of input node 0.
