Struct rust_bert::models::gpt_j::GptJGenerator

pub struct GptJGenerator { /* private fields */ }

Language generation model based on the GPT-J architecture

Implementations

impl GptJGenerator

pub fn new( generate_config: GenerateConfig ) -> Result<GptJGenerator, RustBertError>

Build a new GptJGenerator

Arguments

• generate_config - GenerateConfig object containing the resource references (model, vocabulary, configuration), generation options and device placement (CPU/GPU)

Example

use rust_bert::gpt_j::GptJGenerator;
use rust_bert::pipelines::generation_utils::GenerateConfig;

let generate_config = GenerateConfig {
    max_length: Some(30),
    do_sample: true,
    num_beams: 5,
    temperature: 1.1,
    num_return_sequences: 3,
    ..Default::default()
};
let gpt_j_generator = GptJGenerator::new(generate_config)?;

pub fn new_with_tokenizer( generate_config: GenerateConfig, tokenizer: TokenizerOption ) -> Result<GptJGenerator, RustBertError>

Trait Implementations

impl LanguageGenerator for GptJGenerator

fn generate<S>( &self, prompt_texts: Option<&[S]>, generate_options: Option<GenerateOptions<'_>> ) -> Result<Vec<GeneratedTextOutput>, RustBertError>

where S: AsRef<str> + Send + Sync,

Generate text based on a vector of promp texts.

fn generate_indices<S>( &self, prompt_texts: Option<&[S]>, generate_options: Option<GenerateOptions<'_>> ) -> Result<Vec<GeneratedIndicesOutput>, RustBertError>

where S: AsRef<str> + Send + Sync,

Generate token indices without decoding (useful for token-level operations before returning final text or as validation step during training).

fn generate_from_ids_and_past( &self, input_ids: Tensor, attention_mask: Option<Tensor>, generate_options: Option<GenerateOptions<'_>> ) -> Result<Vec<GeneratedIndicesOutput>, RustBertError>

Generate token indices given a list of indices (useful when the input has been pre-tokenized). Returns a list of output tokens that need to be decoded using a tokenizer.

fn get_tokenizer(&self) -> &TokenizerOption

Returns a reference to the text generator’s tokenizer

fn get_tokenizer_mut(&mut self) -> &mut TokenizerOption

fn half(&mut self) -> Result<(), RustBertError>

fn float(&mut self) -> Result<(), RustBertError>

fn set_device(&mut self, device: Device) -> Result<(), RustBertError>
