구글 텐서플로우(tensorflow) 설치해보기

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)

CUDA 다운로드 (https://developer.nvidia.com/cuda-downloads)

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
