model.generate的参数在yaml中设定无效，我设了do_sample: false，使用profiler查看实际还是true 此问题只在训练中途的eval发生，训练结束的最后一次eval正常 #5444

Reminder

  • I have read the README and searched the existing issues.

System Info

  • llamafactory version: 0.9.1.dev0
  • Platform: Linux-6.5.0-27-generic-x86_64-with-glibc2.35
  • Python version: 3.10.12
  • PyTorch version: 2.4.1+cu124 (GPU)
  • Transformers version: 4.45.0.dev0
  • Datasets version: 2.21.0
  • Accelerate version: 0.34.2
  • PEFT version: 0.12.0
  • TRL version: 0.9.6
  • GPU type: Tesla V100-PCIE-32GB
  • DeepSpeed version: 0.15.1
  • Bitsandbytes version: 0.43.3

Reproduction

在 qwen2_vl.yaml中，我写了：

do_sample: false
max_new_tokens: 512

实际使用py-spy查看传入的参数的时候，显示do_sample=true, 没有max_new_tokens，而max_len是我的cut off len.实际上我是想限制生成长度。

根据transformers源代码
https://github.com/huggingface/transformers/blob/8bd2b1e8c23234cd607ca8d63f53c1edfea27462/src/transformers/generation/utils.py#L2967
_sample此时应该已经是false了

经过多次试验，这个参数只有在训练完成后的最后一次eval才会正确传递，训练中途的所有eval都不会

Expected behavior

正确传入model.generate参数
