Grover generator support
Grover released their trained model:
https://github.com/rowanz/grover
I think it should be similar to GPT-2 large. Any plans to support it? 
Maybe if they open source a model larger than the current GPT-2 large.

I'm also happy to welcome PRs to port additional models (as long as they are provided with test/doc/example)<|||||>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.
