Utilities for Generation
|
|
-----------------------------------------------------------------------------------------------------------------------
|
|
|
|
This page lists all the utility functions used by :meth:`~transformers.PretrainedModel.generate`,
|
|
:meth:`~transformers.PretrainedModel.greedy_search`, :meth:`~transformers.PretrainedModel.sample`,
|
|
:meth:`~transformers.PretrainedModel.beam_search`, and :meth:`~transformers.PretrainedModel.beam_sample`.
|
|
|
|
Most of those are only useful if you are studying the code of the generate methods in the library.
