Well, if there are several reports about it, I’m guessing ONNX is doing sth not correctly. I’m not familiar with ONNX, so I can’t say for sure. Like I said, I no longer use that for conversion.
Btw, have u tried deserializing the predict_net.pb file? That’s how I discovered the error. Like I said in that issue, the official model is not giving the correct blob as output. I don’t know if ONNX is behind this crime, though.
Just print the NetDef will be fine.
Here’s problem with the original model:
...
op {
  type: "Int8Softmax"
  top: "325"
  ...
}
op {
  type: "Dequantize"
  bottom: "325"
  top: "network_output"
  ...
}
...
external_output: "325"

which should be external_output: "network_output" at the end.
See if your problem is similar to this one. HTH.
