Question

第一篇文章，所以给我一些时间。

我一直在使用神经网络运行神经网络时遇到问题 g++-8.2.0 -std=c++2a proj1.cpp a

使用Visual Studio运行时，程序可以完美地编译和运行，并根据所需的逻辑执行。使用g ++运行时；但是，代码遇到以下分段错误：

Program received signal SIGSEGV, Segmentation fault.
0x0000000000409100 in std::string::_M_data() const ()
Missing separate debuginfos, use: debuginfo-install glibc-2.17-260.el7_6.4.x86_64
(gdb) where
#0  0x0000000000409100 in std::string::_M_data() const ()
#1  0x0000000000409170 in std::string::_M_rep() const ()
#2  0x0000000000406c4c in std::string::length() const ()
#3  0x0000000000404df6 in main ()

收到此错误后，我添加了一些try-catch块，并尝试使用-g标志重新编译。当使用-g编译时，该程序将不会编译并返回多个多重定义错误。但是，这是唯一使用的文件，所有包含的文件都在std库中。报告的完整错误是：

我不确定问题所在的位置，但是在向我的主文件中添加一些块后，它甚至无法到达第1行，因此我决定同时包含#includes和我的main文件。

#include <iostream>
#include <list>
#include <map>
#include <string>
#include <vector>
#include <random>
#include <fstream>
#include <numeric>


int main()
{
    int numLayers = 4;  //at least 2
    int hiddLayerSize = 16;
    int inputSize;
    int outputSize;
    std::cout << "ERROR BLOCK 1";
    std::vector<std::vector< std::string >  > letters;
    try{
        letters = bdfReader("ie9x14u.bdf");
    }catch (std::exception const &e){
        std::cout << "FILE READ ERROR\n";
        return -1;
    }

    std::vector<std::string> starLetters;
    std::cout << "ERROR BLOCK 2";

    std::vector<std::string> letterInput = sampleInp(letters);
    std::vector<std::string> letterOutput = std::vector<std::string>(26, "00000000000000000000000000");

    /* This was where I thought the problem might be occurring since it mentioned string errors, but after commenting it out, nothing happened

    for (int i = 0; i < 26; i++) {
        letterOutput[i][i] = '1';
    }
    */





    inputSize = letterInput[0].length();
    outputSize = letterOutput[0].length();



    Network* letterNet = new Network(majorityInput, majorityOutput, numLayers, hiddLayerSize, inputSize, outputSize);


    std::pair<std::vector<std::string>, std::vector<std::string> > majExamp = std::pair<std::vector<std::string>, std::vector<std::string> >(majorityInput, majorityOutput);

    std::pair<std::vector<std::string>, std::vector<std::string> > letterExamp = std::pair<std::vector<std::string>, std::vector<std::string> >(letterInput, letterOutput);

    letterNet = backPropLearn(letterExamp, letterNet);

    std::cout << weightsPrinter(letterNet);
    std::cout << std::to_string(networkAcc(letterExamp, letterNet)) + "* 100%\n";
    std::cout << "\n all done";


    return 0;

}

任何帮助将不胜感激。如前所述，该程序可以在Visual Studio 2017中完美地编译和执行。

重新定义错误可能导致分段错误问题（1个文件）
