Convert the .pb to .onnx file from HandTracking project

Lin Hsiehcheng

Hi:

We would like to porting a handtracking project from below

https://github.com/victordibia/handtracking

handtracking/hand_inference_graph/frozen_inference_graph.pb

We known the limited about tensorflow but convert the model /data1/handtracking-master/hand_inference_graph/frozen_inference_graph.pb to /data1/handtracking-master/hand_inference_graph/frozen_inference_graph.onnx and refer from Doc "Onnx Converter/4 Tensorflow to ONNX" command at below

python /workspace/libs/ONNX_Convertor/optimizer_scripts/tensorflow2onnx.py /data1/handtracking-master/hand_inference_graph/frozen_inference_graph.pb /data1/handtracking-master/hand_inference_graph/frozen_inference_graph.onnx

How to solve this problem ?

Is tensorflow version releated?

Hi Lin Hsiehcheng,

The TensorFlow version should not cause this wrong result.

Here are two points to show you.

1.

The Forezen_model.pb you provided contains a lot of preprocess and postporcess because preprocess and postporcess may have Tensorflow Op that cannot support tf2onnx-support-status (https://github.com/onnx/tensorflow-onnx/blob/master/support_status .md#tf2onnx-support-status this link dead --> https://github.com/onnx/tensorflow-onnx/blob/master/support_status.md ), resulting in an unsuccessful conversion to onnx.

2.

From our experience, you can try converting Forezen_model.pb into tflite format and then use our Kneron ToolChain docker after that.
