Question about mask Observation

[XueyangFeng]

Hello, thanks for your great work!
I see that you try to mask the Observation line in your lora fine-tune code, but why you not use the masked label ? I think this line maybe "result["labels"] =ids"
"

FireAct/finetune/llama_lora/finetune.py

Line 146 in 94c6189

result["labels"] = result["input_ids"].copy()

Looking forward to your reply!
