mac 系統(tǒng)OS X EI capitan時(shí)遇到一些問題：

1. 采用pip安裝，進(jìn)行到利用pip install tensorflow時(shí)報(bào)錯(cuò):

sudo方式同樣無效，推測可能是OSX的安全策略導(dǎo)致修改系統(tǒng)目錄權(quán)限失??？采用VirtualEnv凡是安裝

2. 按照官網(wǎng)VirtualEnv方式完成安裝后。運(yùn)行Python，測試是否安裝成功時(shí)：

 >>> import tensorflow as tf

會(huì)報(bào)錯(cuò)：

Error importing tensorflow.  Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

解決方案參考@raingo 解釋，需要先reinstall protobuf后再reinstall Tensorflow：

  - pip install -U protobuf==3.0.0b2
  - pip install --upgrade $TF_BINARY_URL

注意由于是VirtualEnv安裝方式，需要先啟動(dòng)VirtualEnv。
