MAC上安裝TensorFlow
安迪兒之前是在nas上試玩docker的TensorFlow
最近剛好做個小東西，趁機會記錄一下安裝TensorFlow在mac筆電的步驟

安裝方式
- Pip install:
Install TensorFlow on your machine, possibly upgrading previously installed Python packages. May impact existing Python programs on your machine.
- Virtualenv install:
Install TensorFlow in its own directory, not impacting any existing Python programs on your machine.
- Anaconda install:
Install TensorFlow in its own environment for those running the Anaconda Python distribution. Does not impact existing Python programs on your machine.
- Docker install:
Run TensorFlow in a Docker container isolated from all other programs on your machine.
- Installing from sources:
Install TensorFlow by building a pip wheel that you then install using pip.
安裝pip
如果沒pip的話可以先安裝一下
#Mac OS X
$ sudo easy_install pip
$ sudo easy_install --upgrade six
安裝TensorFlow
安迪兒的Mac筆電沒有顯卡，只能裝CPU版的
CPU版:
pip install tensorflow
GPU版:
pip install tensorflow-gpu
然後踩了一下雷
查了一下發現mac好像都會有這問題
(其實官方文件下面一些有提到不能安裝時的方式)
安迪兒挑了mac內建的python2.7來用
Mac OS X, CPU only, Python 2.7:
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.1-py2-none-any.whl
更新一下tensorflow
# Python 2
$ sudo pip install --upgrade $TF_BINARY_URL
再次踩雷
還是error
安迪兒看了一下文件，覺的可能是和python的版本有關
就手動升了一下mac的python到2.7.13
brew install python
brew info python
brew linkapps python
source ~/.bash_profile
python -v
重來一次
export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.1-py2-none-any.whl
sudo pip install --upgrade $TF_BINARY_URL
安裝成功了
來測試一下tensorflow能不能用吧
$ python
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
Hello, TensorFlow!
>>> a = tf.constant(10)
>>> b = tf.constant(32)
>>> print(sess.run(a + b))
42
>>>
