windows10 tensorflow-gpu 설치

아래와 같은 에러가 뜨면서 아무리 메뉴얼대로 설치해도 잘 안되는경우가 있다.

아나콘다로 설치하면 편하다.

1) 일단 가상환경을 만들고,

conda create --name tf-gpu

2) 가상환경에 들어가자

activate tf-gpu

3) 그리고 cuda, cdnn다 깐다.

(tf-gpu) C:\Users\xx> conda install -c aaronzs tensorflow-gpu

(tf-gpu) C:\Users\xx> conda install -c anaconda cudatoolkit
(tf-gpu) C:\Users\xx> conda install -c anaconda cudnn

4) 실행시킨다.

>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))

그럼 위와같이 잘 나온다. 3만원짜리 똥그래픽카드도 잘나온다.
