在netlogo运行结束时，我想输出520个特定于运行的变量。我用文件写这样做。但是，当我这样做时，创建的输出文件是不完整的。例如，如果我执行1,008次运行，则仅将734.xxx运行的结果写入该文件。这是文件写入命令的代码：

以下是我所做的一些事情：

1）我在作业运行时监视机器上的内存使用情况。我没有观察到记忆似乎不足的情况。但是，我考虑过增加Netlogo对内存的访问权限，并且已经找到了这样做的方法。但是，在没有明确知道这就是问题的情况下，我宁愿不去处理这些深层命令。因此，我先做了几件事。

2）一半的变量是介于-1和1之间的浮点数。我将它们的精度降低到小数点右边的5位数。

3）我没有编写520个变量的文件，而是尝试将变量的子集写入不同的文件（用一个匹配的键）。较小的文件仍然存在问题。但即使是我的小文件也有超过80个字符的行。那是问题吗？要使所有文件每行少于80个字符，我需要至少18个文件。这可以实现，但在实现此响应之前，我宁愿知道这是问题。

4）我在文件的不同位置删除了“文件刷新”（如果我遇到了未观察到的内存问题）。

5）我在整个文件中删除了'file-write'\ n“'命令（如果行太长）。

6）如果我使用错误的“file- *”命令，我将所有内容都切换到文件打印。

7）我五元组检查文件是否实际上是正确的长度，并且我对统计软件包的读数存在缺陷。但是，由于我只是阻止文件写入命令列表并将其复制到包中并删除“文件写入”语言，因此这不是文件错误的基础。该文件实际上已被截断。

8）我在每个文件写命令之后删除了“file-print”“”命令来输入一个单独的行，以防变量互相写入（在我截断浮点数之前）。

我试图运行模型1,008次，每次都设置不同的全局参数。目的是能够在有效的全局参数空间中进行采样。但是，我不能使用行为空间，因为全局参数不是独立的，并且将它们视为独立参数会产生可能性，只有极小部分实际上是有效的组合。因此，使用行为空间至少会浪费大量的时间和计算周期;更有可能的是，使用行为空间会因为有效运行的发生率低而无法进行研究。因此，相反，我已经确定了全局参数的有效组合，并寻求运行它们的一些子集，获得产生的输出，然后分析结果。因此，我需要一些方法来输出总结结果的520个变量。

我感谢任何人都能提供的任何帮助。

答案 0 :(得分：3)

我经常在每次写入文件后调用file-close。我不能为你提供一个很好的技术理由，为什么它会起作用，我知道它并不是一个特别令人满意的解决方案，但在我遇到I / O问题的几个时候，＃＆＃ 39; s通常解决它。为了省去复制/粘贴file-close 519次的麻烦，看看你是否可以生成所有这些的列表，并做一个

foreach list-with-var-names [
  file-open "results.txt"
  file-write ?
  file-close
]

FWIW，当记录学生时＃9;在NetLogo中工作我用file-write编写了10MB +文件，因此每个变量写入520行绝对不是问题。
