我试图让 Matlab 将许多脚本作为单独的批处理作业执行。每个脚本从 excel 表格中加载一些数据并实现一个神经网络。神经网络在内部使用 parfor 循环进行参数调整。

当我在本地机器上运行批处理作业时，它工作正常。我的 Matlab 代码看起来像

job1 = batch('Historical1Step',...
'Profile', 'local',...
'Matlabpool', 3,...
'CaptureDiary',true,...
'CurrentDirectory', '.');

try
    job1Results = fetchOutputs(job1);
catch err
    delete(job1);
    rethrow(err);
end
delete(job1);

我得到的日记输出是

--- Start Diary ---
Analysing data for stock BAX

num_its =

 2

100%[============================
100%[===================================================]

--- End Diary ---

但是，当我从“本地”配置更改为我的服务器配置时，我得到

--- Start Diary ---
--- End Diary ---
Error using parallel.Job/fetchOutputs (line 869)
An error occurred during execution of Task with ID 1.

Error in SOExample (line 14)
    job1Results = fetchOutputs(job1);

Caused by:
    Index exceeds matrix dimensions.

我假设问题与我的函数/数据对工作人员的可见性有关，但我已经尝试了批处理函数中我能想到的“FileDependencies”和“PathDependencies”选项的所有组合，但无济于事。

任何帮助将不胜感激，如果我在没有意识到的情况下做了一些非常愚蠢的事情，请提前道歉！

错误堆栈如下：

Index exceeds matrix dimensions.

文件“Historical1Step”是我要运行的脚本。第一行（直到代码失败）是：

wrkDir = 'V:\Individual\SOFNN'; % this is where the files are on cluster headnode
wrkFldr = [wrkDir '\ExcelSheets\1-stepAhead\']; % location of excel sheets

%%
folder = dir(wrkFldr);
isub = [folder(:).isdir]; % data is stored in sub-directory based on stock symbol
stockNames = {folder(isub).name}'; % extract stock names from names of sub-dirs
stockNames(ismember(stockNames,{'.','..'})) = []; % remove names '.' and '..'

for i = 1:1 % this loop should read in data for stock i from correct sub-dir
    close all;
    clc;
    sym = stockNames{i};
    disp(['Analysing data for stock ' sym]);
    fldrName = strcat(wrkFldr,'\', sym, '\');
end % added for completion

在您的代码中，您在工作人员上使用了映射驱动器号。通常，由于进程的启动方式，工作人员看不到映射驱动器号。请尝试改用 UNC 路径。此处文档中的更多信息：http: //www.mathworks.com/help/distcomp/troubleshooting-and-debugging.html
