# E12029 Invalid_Argument_TensorFlow_Model_Data

#### Symptom

Failed to find the subgraph library.


#### Possible Cause

The model to convert contains function subgraphs, but the graph_def_library.pbtxt file is not found.


#### Solution

1. To use function subgraphs to convert a TensorFlow model, place the subgraph .proto description file in the same directory as the model file and name it graph_def_library.pbtxt.
2. Run the func2graph.py script in the ATC installation directory to save the subgraphs to graph_def_library.pbtxt.
