Work Description: yeandy opened a new pull request, #17470:
URL: https://github.com/apache/beam/pull/17470
We currently only support ability to pass in a single Tensor that does not
have any keys attached to it: `model(input)`. We want to support kwargs like
this: `model(**inputs)`.
Because of the way Beam returns `BatchElements()`, we need to convert a list
of (key to Tensor) dicts into a dict of Tensor lists.
