Question

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

当我在本地计算机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 ---

然而，当我改变本地＆＃39;配置到我的服务器配置我

--- 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.

我假设问题与我的职能/数据在工作人员上的可见性有关，但我已经尝试了＆＃39; FileDependencies＆＃39;的所有组合。和＆＃39; PathDependencies＆＃39;我可以在批处理功能中想到的选项无济于事。

任何帮助都会非常感激，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：

文件＆＃39; Historical1Step＆＃39;是我试图运行的脚本。第一行（直到代码崩溃）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，您正在使用工作人员的映射驱动器号。通常，由于进程的启动方式，工作人员无法看到映射驱动器号。请尝试使用UNC路径。这里的文档中有更多信息：http://www.mathworks.com/help/distcomp/troubleshooting-and-debugging.html
