Predicts the words that will follow a specified text prompt. (experimental)

## Arguments

x

(string) A variable or a tibble/dataframe with at least one character variable.

model

(string) Specification of a pre-trained language model that have been trained with an autoregressive language modeling objective, which includes the uni-directional models (e.g., gpt2).

device

(string) Device to use: 'cpu', 'gpu', or 'gpu:k' where k is a specific device number

tokenizer_parallelism

(boolean) If TRUE this will turn on tokenizer parallelism.

logging_level

(string) Set the logging level. Options (ordered from less logging to more logging): critical, error, warning, info, debug

return_incorrect_results

(boolean) Stop returning some incorrectly formatted/structured results. This setting does CANOT evaluate the actual results (whether or not they make sense, exist, etc.). All it does is to ensure the returned results are formatted correctly (e.g., does the question-answering dictionary contain the key "answer", is sentiments from textClassify containing the labels "positive" and "negative").

return_tensors

(boolean) Whether or not the output should include the prediction tensors (as token indices).

return_text

(boolean) Whether or not the outputs should include the decoded text.

return_full_text

(boolean) If FALSE only the added text is returned, otherwise the full text is returned. (This setting is only meaningful if return_text is set to TRUE)

clean_up_tokenization_spaces

(boolean) Option to clean up the potential extra spaces in the returned text.

prefix

(string) Option to add a prefix to prompt.

handle_long_generation

By default, this function does not handle long generation (those that exceed the model maximum length).

set_seed

(Integer) Set seed. (more info :https://github.com/huggingface/transformers/issues/14033#issuecomment-948385227). This setting provides some ways to work around the problem: None: default way, where no particular strategy is applied. "hole": Truncates left of input, and leaves a gap that is wide enough to let generation happen. (this might truncate a lot of the prompt and not suitable when generation exceed the model capacity)

## Value

A tibble with generated text.
