Ubuntu中NumCpp安装教程

Ubuntu上NumCpp安装教程

NumCpp是python中numpy库的c++版本。

1. 下载NumCpp

   git clone https://github.com/dpilger26/NumCpp.git
   

2. 下载boost，下述安装链接为范例，需要随boost版本升级进行修改…

wget https://boostorg.jfrog.io/artifactory/main/release/1.81.0/source/boost_1_81_0.tar.gz

3. 安装boost依赖库

sudo apt update
sudo apt install libboost-all-dev
dpkg -S /usr/include/boost/version.hpp #检查boost版本

3. 解压、编译并安装boost包

tar -zxvf boost_1_81_0.tar.gz
cd boost_1_81_0
./bootstrap.sh --with-libraries=all --with-toolset=gcc
sudo ./b2 install --prefix=/usr

4. 编译NumCpp库

cd NumCpp
mkdir build
cd build
cmake ..
sudo cmake --build . --target install

5. 测试NumCpp是否安装成功

cd ..

创建cpp文件test.cpp,输入以下命令：

#include <iostream>
 
#include "NumCpp.hpp"
 
int main() {
        nc::NdArray<float> a = {{1, 2}, {3, 4}};
        nc::NdArray<float> b = {{1, 2}, {3, 4}};
        nc::NdArray<float> c = a * b;
 std::cout << c[0] << std::endl;
 
 return 0;
}

编译运行test.cpp文件（注意，这里的编译器必须是c++14以上)

g++ -o test test.cpp --std=c++14
./test

输出：

1

通过测试。
