Tensorflow 学习笔记（一）mac os 安装 tensorflow

Homebrew 安装python

brew install python

安装pip

curl ‘https://bootstrap.pypa.io/get-pip.py’ > get-pip.py
python get-pip.py

ps: 安装完之后注意在PATH中指定pip的路径

安装tensorflow

pip3 intall tensorflow

安装中可能会出现timeout error，此时可以尝试：

pip --default-timeout=1000 install -U tensorflow

或者

#python 2.7, cpu only
下载https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.11.0rc0-py2-none-any.whl文件
pip install xx.whl

#python 3.6, cpu only
下载https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.11.0rc0-py3-none-any.whl文件
pip install xx.whl

安装keras

pip3 install keras

验证安装是否正确

python

import tensorflow as tf

from keras.models import Sequential

hello = tf.constant('Hello, TensorFlow!')

sess = tf.Session()

sess.run(hello)

model = Sequential()

自此，tensorflow安装完毕，后面会逐渐用tensorflow写一些实例
