Hi, I have issues when exporting PointRend model with ONNX.

Particularly, this code gets me the errors below:

> 2037 defined in (%2037 : Long() = onnx::Mul(%2031, %2036) # detectron/projects/PointRend/point_rend/point_features.py:138:0
> )
E   RuntimeError: Unexpected node type: onnx::Mul

Is it officialy supported ? Has anyone had success doing so ?

Thanks much for any insights.
