ValueError: batch_dims != 0 is not supported for ragged gather yet.
Hi @beanduan22 ,

As the exception indicates ragged tensor gather won't yet support with `batch_dims != 0`. It is intended behaviour.

Also the innermost dimension of indices should not be ragged.The indices were changed to make it workable. Please refer attached [gist](https://colab.sandbox.google.com/gist/SuryanarayanaY/8cd19a1e2b75506962626142a4e5eda2/62544.ipynb).
