Issue about converting onnx file to the nef file

mint · August 2021

I want to convert my own onnx model file into the nef file by using the example provided in the document center (YOLO example)

After I installed and entered the docker environment, tried to run the onnx2nef.py, but only got this error

mint · August 2021

And the environment is UBUNTU 20.04.2

Hi mint,

your onnx need some modification,

Our kl520 could not support Transpose node, you need to remove it.
Our toolchain need input shape and all feature map shape information, "?" or "M1", "M2" are not acceptable

I guess you tried 3rd party tool for onnx conversion.

Please make sure your onnx could match the following spec.:

opset version == 11
check all operator are supported, you can find the supported list in document center(http://doc.kneron.com/docs/#toolchain/manual/)
input shape and all feature map shape information are correct.
onnx had better could pass onnx2onnx(http://doc.kneron.com/docs/#toolchain/converters/) or ktc.onnx_optimizer.onnx2onnx_flow(http://doc.kneron.com/docs/#toolchain/python_api/)

Thanks.
