在Julia中保存和检索字典的正确方法是什么？ [英] What is the correct way to save and retrieve dictionaries in Julia?

问题描述

我已经看到，朱莉娅正确地解释了在其中有结构的MAT文件，这些文件是没有问题地读作字典的。现在我已经创建了一个我自己的字典，它具有以下结构：

 （String，String）=> [Int，Int，Int] 
  

我可以用 writeddlm 来保存它，它会生成一个非常有序的
表格文本文件，由制表符分隔（ \ t ），但是如果不进行大量的解析，我就无法检索它。如果我使用 readdlm ，我得到一个Any类型的数组，每行的结构非常不舒适。

 （\Bla bla \，\tururu\）[a，b，c]
  ''和等符号的两列字符串， '['。
解决方案
您可以使用 JLD   HDF5 （Julia Data）子模块> 包：
 使用HDF5，JLD $ b $ Pkg.add（HDF5）
 bd = Dict（
（a，b）=> [1,2,3]，
（c，d）=> [4,5,6 ]，
（e，f）=> [7,8,9] 
）
 save（data.jld，data，d）
 load（data.jld）[data] 
  
 
 
 
 
 
 JLD模块的优势在于它保留了每个变量的精确类型信息。

I have seen that Julia adecuately interprets "MAT" files which have structures in them which are read as dictionaries without problem. Now I have created a dictionary of my own, which has the following structure
(String, String)=> [ Int, Int, Int]
on each entry. I can save it with writeddlm and it produces a very orderly
tabular text file, separated by tabs (\t), but then I cannot retrieve it without doing a LOT of parsing. If I use readdlm I get an array of type Any, with the very unconfortable structure at each line
"(\"Bla bla\", \"tururu\")"     "[a, b, c]"
That is, two columns of Strings which contain signs such as '"' and '['.  
解决方案
You could use the JLD (Julia Data) submodule included in the HDF5 package:
Pkg.add("HDF5")
using HDF5, JLD
d = Dict(
    ("a", "b") => [1, 2, 3],
    ("c", "d") => [4, 5, 6],
    ("e", "f") => [7, 8, 9]
)
save("data.jld", "data", d)
load("data.jld")["data"]



  
the advantage of the JLD module is that it preserves the exact type information of each variable.
