Hi @victordibia,
I am currently trying to convert the frozen inference graph in the repo to .tflite for integrating with an android application. However, I am trying to do that I am facing errors.
Below is the script that I am using to convert the frozen graph to tflite and the error log is also reference below. It would be great if you can share some insights.
Thanks,
Suraj
Code
`
import tensorflow as tf
localpb = 'frozen_inference_graph.pb'
tflite_file = 'hand_detector.lite'
print("{} -> {}".format(localpb, tflite_file))
converter = tf.lite.TFLiteConverter.from_frozen_graph(
#converter =tf.contrib.lite.TocoConverter.from_frozen_graph(
localpb,
['Const'],
['num_detections'])
tflite_model = converter.convert()
`
Error Log
`frozen_inference_graph.pb -> hand_detector.lite

Hi even i am stuck with the same problem. Were you able to find any solution?
I use the following command:
toco --output_file=trained_model.tflite --graph_def_file=./hand_inference_graph/frozen_inference_graph.pb --input_format=TENSORFLOW_GRAPHDEF --input_arrays=image_tensor --output_arrays=num_detections --input_shapes=1,224,224,3

@Suraj520 @srishtigoelroposo I am facing the same problem. Did you guys have any luck?
same issue..! any alternative solution ?
