ETA on TFEncoderDecoderModel and is BERTShare from https://arxiv.org/pdf/1907.12461.pdf planned?
# 🚀 Feature request

Is there a plan for BERTShare from https://arxiv.org/pdf/1907.12461.pdf to be an option for the EncoderDecoderModel?

Also, I can see that an TFEncoderDecoderModel is on the 'ToDo' list for the [EncoderDecoder Framework](https://github.com/huggingface/transformers/projects/23). Any chance of an expected time of completion of this would be greatly appreciated. 

## Motivation

Having an easy to use seq2seq model integrated into hugging face (with TensorFlow) would help my research immensely. Also, models like BERTShare are much more parameter efficient.

## Your contribution

I am happy to help in any form. Not sure where help is needed tbh.

I think we can keep this open, this looks like a fun project. Pinging @patrickvonplaten to let him know!<|||||>The models of https://arxiv.org/pdf/1907.12461.pdf  are already added. You can check them out here (they are not called shared, but are shared indeed): https://huggingface.co/models?search=google%2Froberta2roberta

Also, I'll be releasing an in-detail notebook about these models on Monday, so stay tuned :-) 

No ETA on TFEncoderDecoder models, but it's definitely on the roadmap :-) <|||||>> The models of https://arxiv.org/pdf/1907.12461.pdf are already added. You can check them out here (they are not called shared, but are shared indeed): https://huggingface.co/models?search=google%2Froberta2roberta

Thanks, I am switching from TF to PyTorch :)<|||||>This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
