  • High-performance tokenization: Rust-based core with Python bindings for speed and ease of use.
  • Train custom tokenizers: Support for BPE, WordPiece, and Unigram to tailor vocabularies.
  • Transformer integration: Seamless compatibility with transformers for easy deployment and alignment tracking.

Quick Start

Run the tokenizer on your dataset to produce token IDs and alignment mappings.

Frequently Asked Questions about huggingface-tokenizers

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I tokenize text for transformer models with high throughput?▼

Train custom tokenizers using BPE, WordPiece, and Unigram algorithms to tailor vocabularies for your specific NLP workflows. This process includes built-in support for normalization, pre-tokenization, and post-processing to refine the final token output.

How do I train a custom BPE or WordPiece tokenizer on my dataset?▼

Train custom tokenizers using BPE, WordPiece, and Unigram algorithms to tailor vocabularies for your specific NLP workflows. This process includes built-in support for normalization, pre-tokenization, and post-processing to refine the final token output.

Does HuggingFace tokenizers provide alignment tracking for production NLP pipelines?▼

HuggingFace tokenizers provides precise alignment tracking for production NLP pipelines by generating alignment mappings alongside token IDs. It enables exact character-to-token mapping during model training and inference.

Can I integrate custom tokenizers with the transformers library?▼

You can integrate custom tokenizers with the transformers library for seamless deployment. This compatibility allows you to apply trained BPE, WordPiece, or Unigram tokenizers directly within standard transformer model workflows.

What is the difference between BPE, WordPiece, and Unigram tokenization?▼

BPE, WordPiece, and Unigram are distinct subword tokenization algorithms for building vocabularies. This Skill supports training and applying all three variants, allowing you to tailor the tokenizer to your specific language model requirements.
