Description

hi, i saw this issue: https://github.com/PINTO0309/tflite2tensorflow/issues/33, and i use docker. want to convert model from mediapipe tflite to pd and quantify the model, but show FileNotFoundError: [Errno 2] No such file or directory: './hand_landmark_full.json' error, what's the problom?

Relevant Log Output

user@90fbb8a901d3:~/workdir$ tflite2tensorflow --model_path hand_landmark_full.tflite --flatc_path ../flatc --schema_path ../schema.fbs --output_pb
output json command = ../flatc -t --strict-json --defaults-json -o . ../schema.fbs -- hand_landmark_full.tflite
../flatc: error: Unable to generate text for hand_landmark_full
Usage: ../flatc [OPTION]... FILE... [-- FILE...]

FILEs may be schemas (must end in .fbs), binary schemas (must end in .bfbs),
or JSON files (conforming to preceding schema). FILEs after the -- must be
binary flatbuffer format files.
Output files are named using the base file name of the input,
and written to the current directory or the path given by -o.
example: ../flatc -c -b schema1.fbs schema2.fbs data.json

thanks for your reply. i tried your response, but still the same error. by the way, the url i pasted doesn't contain the tflite model, but i really got the tflite model previously, maybe the official mediapipe repository delete it.

I can only assume that the command you entered is wrong. Therefore, there is nothing more that I can specifically advise you on. If you are using Docker, it cannot be considered an environmental issue. I guess you don't have a .tflite file.

wget https://storage.googleapis.com/mediapipe-assets/hand_landmark_full.tflite

tflite2tensorflow \
--model_path hand_landmark_full.tflite \
--flatc_path ../flatc \
--schema_path ../schema.fbs \
--output_pb

tflite2tensorflow \
--model_path hand_landmark_full.tflite \
--flatc_path ../flatc \
--schema_path ../schema.fbs \
--output_no_quant_float32_tflite

ok thank you. could it be due to the version of flatbuffer? in docker it's 1.12.0, in the readme it's 2.0.8?

[PINTO0309]

You don't have to worry about anything in particular, just execute the command I suggested above once you start Docker.

[imjking]

ok, succeed now. need to add "sudo" command. thank you.
