conda config --set show_channel_urls yes
conda create -n tensorflow python=3.5

// 启动TensorFlow：

import tensorflow as tf
hello = tf.constant("hello, tensorflow!")
sess = tf.Session()
print(sess.run(hello))

conda install ipython
conda install jupyter

import tensorflow as tf
tf.__version__

//查看环境
conda info --envs
