If you get an error like below while running your app:

[error] [infer_utils.cpp:41] %s

Traceback (most recent call last):

RuntimeError: Failure: Failed to wait for graph to complete

This is likely due to the InferenceOp’s specification of the input tensor name (whether in inference_map or in_tensor_names) not matching the output tensor name of the upstream operator.
