Using T5

[asheetal]

There are some photo-op reasons to use T5 transformer backend in the summarizer. But so far unable to figure out how to connect t5-base with this Summarizer or TransformerSummarizer. Hope someone can point me in the right direction.

Would also like some guidance on this. Getting error: "You have to specify either decoder_input_ids or decoder_inputs_embeds". But once we set Summarizer's custom_model parameter, there is no way to pass those needed parameters.
