Which type is selected if the argument "bf16" is set false in sft yaml? float16? 在sft训练yaml中把bf16这一参数改成false会默认用什么类型训练？

As described above, I wonder is Float16 or Float32 selected after setting "bf16" false in sft training configuration (.yaml)?

我看中文文档里 https://llamafactory.readthedocs.io/zh-cn/latest/getting_started/sft.html，只说了bf16这个参数是“是否使用bf16格式”，那么请问置false的时候，训练时是用的哪个呢？float16还是float32？
