主要功能是讀取deply的層名字，程式碼如下：

#include <vector>
#include <iostream>
#include "caffe/net.hpp"


using  namespace std;
using namespace caffe;
int main(int argc, char *argv[])
{
    string proto("deploy.prototxt");
    Net<float> nn(proto,caffe::TEST);
    vector<string> bn = nn.blob_names();
    for(int i=0;i<bn.size();i++)
    {
        cout<<"Blob #"<<i<<" : "<<bn[i]<<endl;
    }
    
    return 0;
}
 

程式碼好寫，環境難配，一開始的.pro如下

QT += core
QT -= gui

CONFIG += c++11

TARGET = 1113_test_caffe_net
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

報錯：

fatal error: cublas_v2.h: 沒有那個檔案或目錄

然後看了之前的工程.pro的配置：

加上了

INCLUDEPATH += /usr/local/cuda/include
INCLUDEPATH += /usr/local/include/node

好了，又報錯：

usr/bin/ld: 找不到 -lcaffe

Makefile:242: recipe for target '1113_test_caffe_net' failed

 我知道我編譯的caffe是debug模式，tool目錄下面的caffe都是caffe-d，同樣的lib目錄下面的是_caffe-d.so　、libcaffe-d.so　、libcaffe-d.so.1.0.0　所以，我的應該寫成這樣LIBS += -lcaffe-d。。正確的.pro如下：

QT += core
QT -= gui

CONFIG += c++11

TARGET = 1113_test_caffe_net
CONFIG += console
CONFIG -= app_bundle

所以，程式碼雖簡單，但是它通過呼叫caffe的一些底層程式碼，都需要正確地址的庫和標頭檔案的支援，要不然找不到，比如，這個簡單的程式碼會呼叫cuda和protobuf等，執行結果如下：
