How does the library handle these tokens when decoding back to string? These are the "byte-fallback" tokens. This is crucial for maintaining the context in transformer models.

This is essential for using the llama-2 chat models, as well as other fine-tunes like Vicuna. But anyway, the Llama normalizer adds a SPIECE_UNDERLINE at the beginning of the special tokens, which will thus be a different token. <hashtag> with the '<>' should also be recognized as a unique token.

Indeed, as it was written in the documentation a padding token is required. As noted by u/phree_radical, the things that you referred to as "special tokens" are not actually individual tokens, but multi-token sequences, just like most text sequences are. float16. 3. The model decides for each token, within a particular decoder, which memories are important. It seems with batch and padding, the logits are nan in your case. For those tokenizers that don't have special tokens, but can add special tokens, such as QWenTokenizer or PhiTokenizer. Always answer as helpfully as possible, while being safe.
