Header File/Library File
- Header file: #include <ge/ge_api.h>
- Library file: libge_runner.so
Function Usage
Binds a graph with a specified ID to a stream in asynchronous graph execution scenarios.
Before calling this API, you need to complete the CompileGraph process. After LoadGraph is complete, you need to call the ExecuteGraphWithStreamAsync API to execute the graph.

Parameters
|
Parameter |
Input/Output |
Description |
|---|---|---|
|
graph_id |
Input |
ID of the graph to be executed. |
|
options |
Input |
Options that may be used in the execution phase. A key-value mapping table, for the graph configuration. key indicates the parameter type, and value indicates the parameter value. Generally, this parameter can be left blank, indicating using the same options configuration passed to GEInitialize. The key and value are of the AscendString type. You can use these parameters to configure the current graph separately. For details about the supported configuration options, see Options > ge.exec.frozenInputIndexes and ge.exec.hostInputIndexes. Only these two parameters can be configured currently. |
|
stream (asynchronous graph execution) |
Input |
Graph execution flow. |

Status |
GE_CLI_SESS_RUN_FAILED: Serialization failed when a subgraph is executed. SUCCESS: Subgraph executed successfully. FAILED: Failed to execute the subgraph. |
Restrictions
It is recommended that the stream loaded by LoadGraph be the same as the stream used by the ExecuteGraphWithStreamAsync API. If they are different, call the aclrtSynchronizeStream API to synchronize the stream used for loading after LoadGraph is called.
