Detailed Description

Factory for creating tokenizer trainers and loading vocabularies.

This class centralizes construction and loading logic so CLI tools and applications can remain tokenizer-agnostic. The factory creates trainers and loads vocabularies based on TokenizerType discriminator.

Member Function Documentation

◆ loadTokenizer()

std::unique_ptr< Tokenizer > Mila::Data::TrainerFactory::loadTokenizer	(	TokenizerType	type,
		const std::filesystem::path &	vocabPath )

inlinestatic

Load a tokenizer from a saved vocabulary file.

This loads the vocabulary and creates a tokenizer in one operation. The returned tokenizer owns its vocabulary.

Parameters

type	TokenizerType discriminator (Char, Bpe, etc.).
vocabPath	Path to the saved vocabulary file.

Returns: std::unique_ptr<Tokenizer> Ready-to-use tokenizer.

Example:

auto tokenizer = TrainerFactory::loadTokenizer(
    TokenizerType::Bpe,
    "vocab.bin"
);
auto tokens = tokenizer->encode("Hello, world!");

Here is the call graph for this function:

◆ trainVocabulary()

template<typename Config>

void Mila::Data::TrainerFactory::trainVocabulary	(	TokenizerType	type,
		const Config &	config,
		std::span< const std::filesystem::path >	corpusFiles,
		const std::filesystem::path &	outputPath )

inlinestatic

Train a vocabulary from corpus files.

Creates a trainer with the provided config, adds corpus files, trains the vocabulary, and saves it to disk.
