   Thanks for reply. Can your provide some references show how to  register _rnn_param_concat op as concatenation.

   conversion of other RNN types will need to be added.

   Thanks for reporting. We are removing that op in the RNN layer in the 2.0. It will need to be registered in 1.x. That operator should be registered as simple concatenation for ONNX.

   for export, I think it would be something similar to this:
