Error when I convert the frozen_pb file to tflite

Question

I use the mobileNet pre-trained model for object-detection.I have owned frozen_graph file, and I use tool to know the input_arrays and output_arrays.This is my command:

bazel-bin/tensorflow/contrib/lite/toco/toco \
  --input_file=$(pwd)/mobilenet_v1_1.0_224/frozen_graph.pb \
  --input_format=TENSORFLOW_GRAPHDEF  --output_format=TFLITE \
  --output_file=/tmp/mobilenet_v1_1.0_224.tflite --inference_type=FLOAT \
  --input_type=FLOAT --input_arrays=image_tensor \
  --output_arrays=detection_boxes,detection_scores,detection_classes,num_detections  --input_shapes=1,224,224,3

While I run the commend, the following message appear:

2018-02-16 19:44:08.718034: W 
tensorflow/contrib/lite/toco/toco_cmdline_flags.cc:178] --input_type 
is deprecated. It was an ambiguous flag that set both --
input_data_types and --inference_input_type. If you are trying to 
complement the input file with information about the type of input 
arrays, use --input_data_type. If you are trying to control the 
quantization/dequantization of real-numbers input arrays in the 
output file, use --inference_input_type.

the final error is:

I really don't know what the error mean, can you give me a help? thanks:)

Answer 1

The simple answer is the TFLite doesn't support all TF operations yet. They're being worked on, but that's why you see all the 'unsupported operation' errors.

If you really want your model to work on mobile while awaiting them to be supported on TFLite, check out TensorFlow Mobile, which is a different platform: https://www.tensorflow.org/mobile/
