Contribute to zhangnn520/Llama2-Chinese development by creating an account on GitHub. The real issue is the the Llama families do not have a padding_token and just a pad_id. cpp already does that, with banning of the EOS token a command line argument (--ignore-eos), as does oobabooga's text-generation-webui ("Ban the eos_token" off by default). 16 torch 1.

A few days ago, Open Orca released a new model called Mistral-7B-Openorca. cpp, but it looks like the problem with redefined tokens for the chat fine-tune was simply ignored, the only support for this is that the model conversion script looks for the id of the EOS token to know when to stop generation, Also, when using the Token Counter, the string is treated as a string (resulting in general in 3 tokens) instead of as a single EOS token. pad_token = tokenizer.

I believe the core problem comes from the mixture of chat templates, and the "add_bos" flag in tokenizer_config. However, I'm unclear about the BOS token's usage, particularly in the pretraining phase.

I see that generate_simple() does respect the eos of speech token now (there was another issue where turboderp suggested manually setting stop condition in generator, but that appears to no longer be relevant). @Aisuko I think the problem is that your model has "add_eos_token": true, in tokenizer_config. tokenization_llama. This happens when the eos_token is not defined or recognized in the tokenizer configuration for the llama3 base model.
