Takes less than 20 seconds to tokenize a GB of text on a server's CPU. - Easy to use, but also extremely versatile. - Designed for research and production. - Normalization comes with alignments tracking. It's always possible to get the part of the original sentence that corresponds to a given token. - Does all the pre-processing: Truncate, Pad, add the special tokens your model needs. ## Performances Performances can vary depending on hardware, but running the [~/bindings/python/benches/test_tiktoken.py](bindings/python/benches/test_tiktoken.py) should give the following on a g6 aws instance:  ## Bindings We provide bindings to the following languages (more to come!): - [Rust](https://github.com/huggingface/tokenizers/tree/main/tokenizers) (Original implementation) - [Python](https://github.com/huggingface/tokenizers/tree/main/bindings/python) - [Node.js](https://github.com/huggingface/tokenizers/tree/main/bindings/node) - [Ruby](https://github.com/ankane/tokenizers-ruby) (Contributed by @ankane, external repo) ## Installation You can install from source using: ```bash pip install git+https://github.com/huggingface/tokenizers.git#subdirectory=bindings/python ``` or install the released versions with ```bash pip install tokenizers ``` ## Quick example using Python: Choose your model between Byte-Pair Encoding, WordPiece or Unigram and instantiate a tokenizer: ```python from tokenizers import Tokenizer from tokenizers.models import BPE tokenizer = Tokenizer(BPE()) ``` You can customize how pre-tokenization (e.g., splitting into words) is done: ```python from tokenizers.pre_tokenizers import Whitespace tokenizer.pre_tokenizer = Whitespace() ``` Then training your tokenizer on a set of files just takes two lines of codes: ```python from tokenizers.trainers import BpeTrainer trainer = BpeTrainer(special_tokens=["[UNK]", "[CLS]", "[SEP]", "[PAD]", "[MASK]"]) tokenizer.train(files=["wiki.train.raw", "wiki.valid.raw", "wiki.test.raw"], trainer=trainer) ``` Once your tokenizer is trained, encode any text with just one line: ```python output = tokenizer.encode("Hello, y'all! How are you 😁 ?") print(output.tokens) # ["Hello", ",", "y", "'", "all", "!", "How", "are", "you", "[UNK]", "?"] ``` Check the [documentation](https://huggingface.co/docs/tokenizers/index) or the [quicktour](https://huggingface.co/docs/tokenizers/quicktour) to learn more!
