@gaojun4ever 应该是repetition_penalty比较高了，可以试一下1.02或1.0，这个参数的设置对于代码和文本生成效果似乎有点tradeoff，我们也在readme里调低一下。感谢反馈🙏

我用其他模型测试也发现这个参数repetition_penalty很敏感，调低了容易重复，高了影响效果

补充一些leetcode的测试case，基本写不好代码问题

Q1: 根据题目写出代码：给你两个 非空 的链表，表示两个非负的整数。它们每位数字都是按照 逆序 的方式存储的，并且每个节点只能存储 一位 数字。请你将两个数相加，并以相同形式返回一个表示和的链表。

MOSS:
class ListNode:
def init(self, val=0, next=None):
self.val = val;
self.next = next;

    # 实现加法运算的方法1（递归）

    def addTwoNumbers_recursive (lnode2) :

             if lnode == None || mlist=="": return 0     ## 链表为空或只有一个节点的情况    直接返回0       


                     x=(int)(mlist[i]) + y ; // x代表当前位上的和        y则代表了下一个位的值          //如果还有进位需要处理           carry='true'             while carry!="false" &amp;&gt;/lt; -10**6+7 ,              temp=[];            sum=""               for j=-3 downto 3 do                    numeral=~j-(~5);                  numeralsum+=str((char)!d%b)+'; '                   z:=v*c % 10 ^ v * d / b << 1 >> 2^w w += 4 | z >>> 9 .                       temptemp<<chr(_a>>4)|e{f}[_g] _h++;                      u++                                         k--                 elif k>8 && !isinstance("".join([m for n,[p,""]][q]),long)) then                     break                              else c -= ((new long)[tmp]-48)/16                        continue                            end                           addtwo={};                         resutlListAddOne();                return resultListEnd()                               resultLstNumToString().append('[').extand({}.concat()) end;;

                             @staticmethod def printLinkedListInReversePrint(): #打印链表的逆向字符串方法print Linking list In Reverse Print；

Q2: 根据题目写出代码：给定一个整数数组 nums 和一个整数目标值 target，请你在该数组中找出 和为目标值 target 的那 两个 整数，并返回它们的数组下标。

MOSS:
下面是一个 Python 的示例实现:

def twoSum(nums,target):

  # 使用字典记录每个数字对应的下标及其差值的和
    dict = {} # 记录已经遍历过的元素及其总和的列表
     for i ,num1_sum     i n m ( 0 <= j < len ( l ) : dict [ str ( k + 1 )] += int ([ ] . join (( map ({ lambda x :( '%d % d' %((x+j)%(len([*l])))).split()))[0]) ##将字符转换为int类型并进行求和）}                                       if sum - targe r == s h u ml _ e v en g () != 2 * y o f p ar c et te rs ): return [] ; else: pass;

             return [(k+2)*['a']for key,,value][::(-3)]             ##从最后一个开始往前取出所有奇数位索引的元素（因为需要找到的是前两个数的组合），并将其转换回字符串形式作为输出结果              
      
       print("result",twoS um(_list=[],targ er="12345"))         //测试用例输入为"[]"，期望的输出结果是["4","5"] <eom>

@gaojun4ever 请给出具体用的哪个ckpt以及生成参数，这都生成乱码了肯定是生成参数有点问题。以及能否给出chatglm对应的输出？

感谢回复，这是我按照官方代码起的一个服务 https://huggingface.co/fnlp/moss-moon-003-sft，用的是moss-moon-003-sft模型。结果还在整理，不知道代码有没有问题。
