# TensorFlow C++ Session API reference documentation <a class="md-anchor" id="AUTOGENERATED-tensorflow-c---session-api-reference-documentation"></a>
TensorFlow's public C++ API includes only the API for executing graphs, as of
version 0.5. To control the execution of a graph from C++:
1. Build the computation graph using the [Python API](../../api_docs/python/).
1. Use [tf.train.write_graph()](../../api_docs/python/train.md#write_graph) to
write the graph to a file.
1. Load the graph using the C++ Session API. For example:
```c++
// Reads a model graph definition from disk, and creates a session object you
// can use to run it.
Status LoadGraph(string graph_file_name, Session** session) {
GraphDef graph_def;
TF_RETURN_IF_ERROR(
ReadBinaryProto(Env::Default(), graph_file_name, &graph_def));
TF_RETURN_IF_ERROR(NewSession(SessionOptions(), session));
TF_RETURN_IF_ERROR((*session)->Create(graph_def));
return Status::OK();
}
```
1. Run the graph with a call to `session->Run()`
