ubuntu+python基础-3 安装tensorflow踩过的坑

0. sudo apt-get install python-pip python-dev

    先安装这两个包

1.对python版本要求比较细致，精细到副版本号，要注意，可以参考https://blog.csdn.net/shuzfan/article/details/78516542

Python 2.7

// CPU版本
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp27-none-linux_x86_64.whl
// GPU版本
pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.4.0-cp27-none-linux_x86_64.whl

Python 3.4

// CPU版本
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp34-cp34m-linux_x86_64.whl
// GPU版本
pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.4.0-cp34-cp34m-linux_x86_64.whl

Python 3.5

// CPU版本
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp35-cp35m-linux_x86_64.whl
// GPU版本
pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.4.0-cp35-cp35m-linux_x86_64.whl

Python 3.6

// CPU版本
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.4.0-cp36-cp36m-linux_x86_64.whl
// GPU版本
pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.4.0-cp36-cp36m-linux_x86_64.whl2.dd

2.据说GPU版本只支持N卡，不支持A卡（没有验证）
3.下载太慢，可以在system setting->software&updates->ubuntu software->Danwload from->other选择源，找到china，选择一个，清华，中科大对教育网友好，速度比较快，阿里云比较靠谱
4.笔记本下载cpu版就行，gpu版提升效果不大，而且后期使用还要额外配置
5.如果不是在虚拟环境安装，要带上sudo，直接pip会报错。

安装完了pip list 看一下是否有

tensorflow             1.4.0      
tensorflow-tensorboard 0.4.0  

然后在Terminal中

(vegen3) yc@yc-ubuntu:~/vegen3$ python
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
>>> hello = tf.constant('Hello,TensorFlow!')
>>> sess = tf.Session()
2018-04-06 10:24:31.873594: I tensorflow/core/platform/cpu_feature_guard.cc:137] Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX AVX2 FMA
>>> print (sess.run(hello))
b'Hello,TensorFlow!'

能显示最后一行表示安装成功
