use custom layer in builder

[reymondzzzz]

Hi! I created custom layer for torch, registrated in onnx ops and converted in onnx model finaly. Also I wrote trt plugin for this layer. Model builded correctly, but I set all parameters from onnx attributes like constant. How can I get attributes in plugin from onnx model. Can I do it without modify onnx parser and rebuild this repo?

@reymondzzzz You would need implement the conversion from the ONNX model to your plugin attribution. Others don't know how to convert it.
