error in Training custom TensorFlow networks for JeVois tutorial

Question

While doing the "Training custom TensorFlow networks for JeVois" tutorial at http://jevois.org/tutorials/UserTensorFlowTraining.html , I got error when executing the command:

toco \

--input_file=tf_files/retrained_graph.pb \

--output_file=tf_files/optimized_graph.pb \

--input_format=TENSORFLOW_GRAPHDEF \

--output_format=TENSORFLOW_GRAPHDEF \

--input_shape=1,${IMAGE_SIZE},${IMAGE_SIZE},3 \

--input_array=input \

--output_array=final_result

The error message is: 

toco: error: argument --output_format: invalid choice: 'TENSORFLOW_GRAPHDEF' (choose from 'TFLITE', 'GRAPHVIZ_DOT')

Answer 1

yes, you are probably using a newer version of toco.

I just edited that tutorial yesterday about that but the new version is not yet live as I want to try it first.

Basically, you should locate the original tensorflow for poets: tflite android, and, in there, look at how they invoke toco. Instead of 2 calls to toco as was the case when we wrote the tutorial, now there is only one call to toco.
