ubuntu14.04安装tensorflow遇到的坑

此处参考http://blog.csdn.net/langb2014/article/details/51579491

Tensorflow

1、先下载v0.8版的GPU支持

[cpp] view plain copy

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

2、如果中途安装不了可以先下载那个网址东西，下载好了，然后安装，中途会有几个包的numpy、six、protobuf、wheel下载安装比较慢或者下载不了，可以单独安装。

[cpp] view plain copy

1. sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl  

3、测试Tensorflow

[cpp] view plain copy

1. python  
2. >>> import tensorflow as tf  
3. >>> exit() 
   

运气好的到此结束，但是基本都会遇到问题，一下内容只适用于我，读完再操作，我遇到问题有

SSLError: The read operation timed out

Storing debug log for failure in /home/hjxu/.pip/pip.log

这是什么情况，我的机器本来没有安装tensoeflow，所以我安装tensorflow没有--upgrate这句

1. sudo pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl 
   

然后又遇到

wnloading/unpacking numpy>=1.8.2 (from tensorflow==0.8.0)
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement numpy>=1.8.2 (from tensorflow==0.8.0)

what fuck？查资料后参考http://www.th7.cn/Program/delphi/201509/553938.shtml

这是源的问题，正常安装你的根目录下会有这个.pip这个文件夹，ctrl+h可见，在这个文件夹下建立pip.conf文件。代码如下

cd .pipsudo touch pip.conf   #建立pip.conf文件sudo gedit pip.conf   #编辑pip.conf文件

然后输入[global]index-url=http://pypi.douban.com/simplev2ex:http://pypi.v2ex.com/simple      保存退出

然后再重新安装

 sudo pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl 

又遇到SSLError: The read operation timed out

总是这么命运多舛

后来发现可能是pip版本问题，执行下面代码

sudo pip install --upgrade pip

然后再安装

sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

然后出现

在终端 测试了一下

pythonimport tensorflow

没有报错，OK，解决了，之前还有一次遇坑

AttributeError: NewBase is_abstract, ImportError: libcudart.so.7.5

解决：是因为six版本问题。

[cpp] view plain copy

1. $sudo pip install six --upgrade --target="/usr/lib/python2.7/dist-packages" 
   

祝好运
