Thanks for reporting this issue @eagle705. This notebook is sorely outdated and should be revamped to showcase:

• How to export models with different topologies (e.g. causal LM heads, masked LM heads etc)
• How to run basic inference with ONNX Runtime, i.e. no optimisation techniques which are now the domain of our optimum library

For point (2) I'd like to show how one can wrap ONNX Runtime InferenceSessions as pipelines (with pre- and post-processing), similar to what was done in Chapter 8 of the NLP with Transformers book or as @ChainYo did in his blog post

I'll get around to this at some point, but if anyone wants to tackle it beforehand they're very welcome!
