Original GitHub issue: https://github.com/kvcache-ai/ktransformers/issues/777

max-new-tokens设置了8K，输入了一个数学问题，生成了很长的回答之后异常中断了。
generate如下：
好，我现在要解决这个关于三角函数的问题。题目给出的是函数f(x) = sin(ωx - π/6)，其中ω > 0，问题是在区间（0，π/2）内f(x)恰好有三个极值点，然后判断四个选项中哪个是不正确的。首先我要理解题目里的每个条件以及每个选项的内容，所以可能需要一步一步分析。

此处省略N字。。。。

需要添加一个参数 --cache_lens, 长度设为最大可能的 token 数
