Convert mask rcnn to onnx failed. RuntimeError: ONNX export failed

See original GitHub issue

Hi, I was trying to convert a mask rcnn model (maskrcnn-benchmark) to onnx model. I encountered this error

RuntimeError: ONNX export failed: Couldn't export Python operator _NewEmptyTensorOp

I think that is some class defined here https://github.com/facebookresearch/maskrcnn-benchmark/blob/master/maskrcnn_benchmark/layers/misc.py#L18 Anyone has any solutions?

You can try export fastercnn to onnx first, It would be much more easy.

The reason for this error is because the example image I used, my maskrcnn could not detect any masks so for some layers the input is of size 0. Using another image from the training set solves the problem. Now I can export to onnx.

@WonderAndMaps Can you please share your work in convert maskrcnn to onnx? Thanks in advance!
