구글이 딥러닝이나 머신러닝을 위해 오픈소스로 배포한 라이브러리.


레퍼런스는 https://www.tensorflow.org/versions/master/get_started/os_setup.html#train-your-first-tensorflow-neural-net-model



작업 환경


맥북 프로, OX X 10.11.4


i5 2.9GHZ


16G Memory




설치 요구 사항


1. 파이썬 2.7이나 3.3 이상


2. CUDA 툴킬 7.5, cuDNN 4 에 최적이며 다른 버전은 소스에서 설치할 수 있음 (Cuda toolkit >= and cuDNN 6.5(v2), 7.0(v3), v5)




dmg로 인스톨하기


next만 눌러주면됨.  sample은 필요없으면 체크 해제.












설치 방법은 무려 5가지.


1. Pip로 설치 : 파이썬 패키지 관리 툴인 pip를 이용해 설치. 이전 설치 버전을 업그레이드 할 수 있음.


2. Virtualenv설치 : 파이썬 가상 환경을 만들어서 인스톨


3. Anaconda 설치 : 파이썬 기반의 데이터 분석용 오픈 소스를 모아놓은 개발 플랫폼 같은 것인 아나콘다에 설치


4. 도커 설치 : 도커 컨테이너에 설치하여 사용


5. 소스 빌드하여 설치 : 소스 코드를 빌드하여 설치



pip로 설치해보기~

근데 이제 뭘해야하지...

node.js에서 http 요청 하기


request 모듈 이용(https://github.com/request/request#examples)



$ npm install request


1. get 요청해보기


var request = require('request');

request('http://naver.com', function (err, response, body) {
  if (err) {
    return console.log('error');
  }
  if (response.statusCode !== 200) {
    return console.log('status : ' + response.statusCode);
  }
  console.log(body);
});
