Convert onnx model err

[nullian]

I hava compiled the mnn converter successful. When i convert a onnx model to mnn use :

./MNNConvert -f ONNX --modelFile mobilefacenet.onnx --MNNModel mobilefacenet.mnn --bizCode MNN

and i face this error:
MNNConverter Version: 0.0.0.1 - MNN @ 2018

Start to Convert Other Model Format To MNN Model...
[09:36:17] /home/yuanhao/osc/MNN/tools/converter/source/onnx/onnxConverter.cpp:29: ONNX Model ir version: 3

How can i solve this problem, thanks!

Hi @nullian ,
How (or where) did you get mobilefacenet.onnx model. I have tried to convert original MXNET models (from insightface) to ONNX models but not successful.
Could you please send me your mobilefacenet.onnx model?
Many thanks.

Hi, may I ask how does the Conv op converter registered? Since the Convolution only supported caffe and Tensorflow.

how does onnx conv parsed?
