Any example to accelerate BART/MBART model with onnx runtime？
# 🚀 Feature request

<!-- A clear and concise description of the feature proposal.
     Transformers.onnx provided a simple way to convert the bart/mbart model to onnx model. But there is no example about how these model could be actually exc by onnx runtime. Bucause some onnx models may occur various of errors. Could you please provide some examples about using onnx runtime to exc these models ?

The transformer.onnx provides a simple to convert hf models to onnx models. But there is no examples about how to exc them by onnx runtime. Some onnx models actually would meet some errors exc with onnx runtime. Could you please provide some examples and experiments about running them with onnx runtime?
