onnc-umbrella bulit onnc reports "unsupported operator" when parsing lenet.onnx

[jinchenglee]

Built both release/debug version of onnc from onnc-umbrella, it complains:

> onnc -mquadruple nvdla ./lenet.onnx
NvDla is invoked
Fatal: Meet unsupported operator: import/conv1first/BiasAdd.```

Is this expected? 

When running the docker image tutorial (https://github.com/ONNC/onnc-tutorial/blob/master/lab_1_Environment_Setup/lab_1.md), the .onnx to .nvdla conversion is completed successfully. Seems like a onnc version differences caused issue.

Or shall I move this issue to onnc repo?

According to your error message, I think it's due to the ONNX model you used. The error message shows there is an unsupported operator.

Different tools (ML frameworks -> ONNX) use different ONNX operator set, maybe you can try other tools. LeNet is a simple & small model, NVDLA backend supported operator should be enough.

Or you can just wait. Current open source version NVDLA backend only supports about 15 ONNX operators ( https://github.com/ONNC/onnc/blob/master/Operator.md ). I think it will support more operators in the next version.

Thanks for prompt reply. I'll just wait for next release.

BTW, just for your inference, I used the lenet.onnx provided in your lab 1. So apparently the docker version of onnc is way ahead of the git repository one. :P
