| ## google/BertTokenizer | |
| - https://github.com/huggingface/tokenizers/blob/main/bindings/python/py_src/tokenizers/implementations/bert_wordpiece.py | |
| - 特征 | |
| - 算法：BERT的编码器是 BPE-WordPiece，将单词拆分成多个前缀符号（比如BERT中的##）最小单元 | |
| - 词典：有##开头的token，表示subword， | |
| - 中文采用char粒度分词 | |
| - 英文采用 WordPiece | |
| ## google/sentencepiece | |
| - https://github.com/google/sentencepiece/blob/3863f7648e5d8edb571ac592f3ac4f5f0695275a/src/sentencepiece_model.proto#L48 | |
| - 支持 sentencepiece 和 wordpiece | |
| - sentencepiece 有byte-bpe吗？ | |
| - UNIGRAM = 1; // Unigram language model with dynamic algorithm | |
| - BPE = 2; // Byte Pair Encoding | |
| - WORD = 3; // Delimitered by whitespace. | |
| - CHAR = 4; // tokenizes into character sequence | |
| - wordpiece | |
| - 特征： | |
| - 训练: spm_train --model_type unigram/bpe/char/word | |
| - 特殊符号： Ġ | |
| - 文件: *.sp_model 或 *.model (可选文件 .vocab，) spm简称 (其他格式比如 tokenizer.json是给hf_tokenizer兼容用的) | |
| - 实现: | |
| - 依赖: protobuf | |
| - 训练: `import sentencepiece as spm; spm.SentencePieceTrainer.train` 或 `spm_train` | |
| - 加载: `import sentencepiece as spm; spm.SentencePieceProcessor().Load(vocab_file)` | |
| - 方法: 是SentencePieceProcessor类型，sp_model.id_to_piece，有tokenizer.json tokenizer.model， | |
| - 分词: | |
| - pre_tokenizers.ByteLevel(add_prefix_space=True, use_regex=False) | |
| - 词典: 词典字符有 ▁ (U+2581) ，表示空格或句首。 | |
| - 示例：google-t5, llama，baichuan, orion, | |
| - llama: tokenizer.json(包含model.vocab model.merges) tokenizer.model | |
| - grok: 原始是 .model文件，后面转成了 tokenizer.json | |
| - google-t5: tokenizer.json, spiece.model | |
| - Skywork-13B-Math: tokenizer.model | |
| - xlm_roberta: sentencepiece.bpe.model | |
| - GPT2Tokenizer | |
| - tokenizer.json, vocab.json, merges.txt (https://huggingface.co/openai-community/gpt2) | |
| - vocab.bpe, encoder.json, dict.txt （fairseq版本，不常用，可以忽略这个版本） | |
| ## thu/icetk | |
| - icetk： sentencepiece的分支，支持image_tokenizer。 | |
| - glm, chatglm1, chatglm2 | |
| ## huggingface/tokenizers | |
| - https://github.com/huggingface/tokenizers | |
| - VS sentencepiece | |
| - 支持sentencepiece | |
| - .model转化为 (merges.txt + vocab.json) 或者 tokenizer.json | |
| - https://github.com/huggingface/tokenizers/blob/main/bindings/python/scripts/sentencepiece_extractor.py | |
| - 加载 merges.txt, vocab.json | |
| - SentencePieceBPETokenizer https://github.com/huggingface/tokenizers/blob/v0.19.1/bindings/python/py_src/tokenizers/implementations/sentencepiece_bpe.py#L10 | |
| - 在 sentencepiece基础上，hf_tokenizer支持pre-tokenization的正则表达式，对tab和换行支持更好，支持special token | |
| - 类型： 支持 BBPE, WordPiece or Unigram | |
| - 特征： | |
| - 文件: tokenizer.json(包含后两个文件的内容), merges.txt, vocab.json | |
| - added_tokens 在vocab中不一定存在。 | |
| - 实现: | |
| - 训练: `from tokenizers.trainers import BpeTrainer, UnigramTrainer, WordLevelTrainer, WordPieceTrainer` | |
| - 加载: | |
| - 方法: .model.from_file .model.save .model.token_to_id .model.tokenize | |
| - .model 是 tokenizer.models.BPE 类型 | |
| - 词典有 Ġ "\u0120" 开头 | |
| - 优势 | |
| - | |
| - 示例：gpt2, gpt_neox_20b, moss, bloom, qwen2 | |
| - 优势：相对sentence piece， | |
| - ss | |
| ## openai/tiktoken | |
| - 特征：空格就是空格， | |
| - 示例：gpt3.5 gpt4, qwen, | |
