caffe blob 数据存储 blob.ccp

blob。h函数修改：

void save_to_file(const std::string& file_name);

blob。cpp 的修改：

头文件

#include <fstream>
#include <iostream>
using namespace std;

template <typename Dtype>

void Blob<Dtype>::save_to_file( const std::string& file_name)
{
        FILE* fp = fopen(file_name.c_str(), "wb");
        CHECK(fp);
        fwrite(&num_, sizeof(int), 1, fp);
        fwrite(&channels_, sizeof(int), 1, fp);
        fwrite(&height_, sizeof(int), 1, fp);
        fwrite(&width_, sizeof(int), 1, fp);

        fwrite(data_->cpu_data(), sizeof(Dtype), count_, fp); //for save the forward data

       //fwrite(diff_->cpu_data(), sizeof(Dtype), count_, fp); //for save the backward gradient data

//      fwrite(mydata, sizeof(Dtype), 10000, fp); //cpudata
        fclose(fp);


 //   ofstream fout(file_name.c_str());
        //fout << num_ <<"  "  ;
        //fout << channels_ <<"  "  ;
        //fout << height_ <<"  "  ;
        //fout << width_ <<"  "  ;
        //const Dtype* data = this->cpu_data();
        //for (int i = 0; i < count_; ++i)      {
        //      fout << data[i] <<"  "  ;
        //      //LOG(INFO) << "CPU_data"<<data_->cpu_data()[i];
        //}
        ////fout.write(data_->cpu_data(), strlen(data_->cpu_data));
 //   fout.close();

}

caffe中如何调用并存储数据？

(*top)[0]->save_to_file("top" + this->layer_param_.name());

 bottom[0]->save_to_file("bottom" + this->layer_param_.name());

matlab中如何查看数据？*********************************************************************************************************

function y = read_blob_data(file_name)


fp = fopen(file_name);


num_images = fread(fp, 1, 'int32');
num_channels = fread(fp, 1, 'int32');
num_height = fread(fp, 1, 'int32');
num_width = fread(fp, 1, 'int32');


num_count = num_images * num_channels * num_height * num_width;


data = fread(fp, num_count, 'float');


data = reshape(data, num_width, num_height, num_channels, num_images);
y = zeros(num_height, num_width, num_channels, num_images);
for i = 1 : num_images
    for j = 1 : num_channels
        z = data(:, :, j, i);
        y(:, :, j, i) = z';
    end
end

如何调用？

y = read_blob_data(“zhangsan”);
