** note: **
- The first token might be a whitespace in LLamaTokenizer.
- Open LlaMa的tokenizer is incompatible with original LlaMa
- This tokenizer will encode continuous spaces to ONE space
### updated
#### 2023-06-02
- add special tokens: <|pad|>, <|output|>, <|input|>, <|sep|>, <|emb|>, <|rwd|>, <|ctx|> |
