Function Description

Inputs data to a graph by index.

Prototype

Status FeedDataFlowGraph(uint32_t graph_id, const std::vector<uint32_t> &indexes, const std::vector<Tensor> &inputs, const DataFlowInfo &info, int32_t timeout)

Parameters

Parameter	Input/Output	Description
graph_id	Input	ID of the graph to be executed.
indexes	Input	Index of the input data. The value range is [0, N – 1], where N indicates the number of input data records. The number must be the same as the value of inputs. Example: {0,2}, indicating that the first and third inputs are fed.
inputs	Input	Input tensors of the computational graph, which are memory allocated on the host.
info	Input	Input data flow flag. For details, see DataFlowInfo Data Types.
timeout	Input	Data input timeout, in milliseconds. The value -1 means no timeout limit.

Returns

Parameter	Type	Description
-	Status	SUCCESS: successful data input. FAILED: failed data input. For details about error codes of ACL APIs, see aclError. For details about other error codes, see UDF Error Codes.
