How to use

Convert tflite to json

• First, using google flatbuffer -- flatc，flatc can convert the tflite file to json format

• flatbuffer：https://github.com/google/flatbuffers

• Install it：

  1. download the git
  2. cmake -G "Unix Makefiles" //create the MakeFile
  3. make //create the flatc
  4. make install //install flatc

• Convert to json:

  1. copy the structure file 'schema.fbs' from tensorflow to the root of flatbuffer
  2. #./flatc -t schema.fbs -- xxxxx.tflite
  3. and you get the json
  4. using func tflite2json() change json to dictionary format json

Load into TF native ops

• check your path (test_json) in Code4TFv15/TFLite2TFv15.py

• run Change2NewJson.py and get the new json

• run TFLite2TFv15.py and get a .pb file

• then your can test the speed using .pb/.tflite/OpenCV.DNN
