Transformers: Integration with a retriever Model

[rajo19]

How can I integrate BERT to a retriever model?

Have a look at the ParlAI library and in particular these great models based on BERT by @samhumeau.

Hey @rajo19,
if you want to do Question Answering at scale with a Retriever + Reader pipeline, it might be worth checking out our new haystack project. It builds upon transformers and you can use all the QA models from here as a reader.
