python之将数据帧从 python 传输到 julia

我有一个包含 250 列和 4562 行的数据框。我想在 Julialang 中使用它。我曾尝试使用 HDF5 传输数据，但它在读取文件时出错。 代码:

using HDF5 
using DataFrames   
data=h5open("Database.h5") 
typeof(data) 
println("names \n",names(data)) 
println("\n dump") 
println(names(data)) 
m=data["nse"] 
println(names(m)) 
jj=m["table"] 
s=read(jj) 

这是我得到的错误:

HDF5-DIAG: Error detected in HDF5 (1.10.2) thread 0: 
  #000: H5O.c line 120 in H5Oopen(): unable to open object 
    major: Object header

非常感谢任何帮助!!

请您参考如下方法:

为此我总是使用 feather format .

例如在 python 中

import feather 
feather.write_dataframe(df, "path/to/file.feather") 

然后在 Julia 中

using DataFrames, Feather 
df = Feather.read("path/to/file.feather") 

您也可以从 R 加载/保存。
