TensorFlowのmacでのinstallメモ

virtualEnv経由でのインストールです

$ sudo easy_install pip
$ sudo pip install --upgrade virtualenv

下記で、tensorflowディレクトリが作られる

virtualenv ~/tensorflow
`

下記でvirtualenvをActivateする。

$ cd ~/tensorflow
$ source bin/activate


$ pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

実行pathに移動

$ cd ~/tensorflow/tensorflow


sample.py

import tensorflow as tf

def x2_plus_b(x, b):
    _x = tf.constant(x)
    _b = tf.constant(b)
    result = tf.square(_x)
    result = tf.add(result, _b)
    return result

with tf.Session() as sess:
    result = sess.run([x2_plus_b(2., 3.)])
    print result
