我想设置temperature和sample_num, 可是百炼平台提供的API没法实现采样,设置了不同的温度后,生成的内容也没有区别

一样。我使用
from transformers import Qwen2VLForConditionalGeneration
model = Qwen2VLForConditionalGeneration.from_pretrained(
model_dir, torch_dtype="auto", device_map="auto",
)
加载的模型,然后尝试使用generation_config:
model.generation_config.temperature=new_temperature
generated_ids = model.generate(**inputs,
generation_config=model.generation_config,
max_new_tokens=max_new_tokens)
和 LLAVA-style(直接将 temperature=0.2, do_sample=True 作为 generate() 的 kwargs 部分的参数),都无法观察到 decode 输出有任何改变。
