+#### `onnx_tf.backend.prepare`
+
+<details>
+  <summary>Prepare an ONNX model for Tensorflow Backend.
+
+  </summary>
+This function converts an ONNX model to an internel representation
+of the computational graph called TensorflowRep and returns
+the converted representation.
+
+</details>
+
+
+
+_params_:
+
+`model` : The ONNX model to be converted.
+
+
+`device` : The device to execute this model on.
+
+
+`strict` : Whether to enforce semantic equivalence between the original model
+and the converted tensorflow model, defaults to True (yes, enforce semantic equivalence).
+Changing to False is strongly discouraged.
+Currently, the strict flag only affects the behavior of MaxPool and AveragePool ops.
+
+
+`logging_level` : The logging level, default is INFO. Change it to DEBUG
+to see more conversion details or to WARNING to see less
+
+
+_returns_:
+
+A TensorflowRep class object representing the ONNX model
+
+#### `onnx_tf.backend_rep.TensorflowRep.export_graph`
+
+<details>
+  <summary>Export backend representation to a Tensorflow proto file.
+
+  </summary>
+This function obtains the graph proto corresponding to the ONNX
+model associated with the backend representation and serializes
+to a protobuf file.
+
+</details>
+
+
+
+_params_:
+
+`path` : The path to the output TF protobuf file.
+
+
+_returns_:
+
+none.
