i changed lora to finetune internlm-chat-7b, but this error is not happend.

[gabriel-peracio]

Yes, same here, though in my case I tried it with internlm2-20b (base, non-chat)

The same configuration, but applied to internlm2-7b, appears to work (I did not allow it to conclude as I am not interested in that model)
