本文介绍了如何在ubuntu上以virtualenv方式安装tensorflow。
安装pip和virtualenv：
# Ubuntu/Linux 64-bit
sudo apt-get install python-pip python-dev python-virtualenv
# Mac OS X
sudo easy_install pip
sudo pip install --upgrade virtualenv
创建 Virtualenv 虚拟环境：
进入你想安装tensorflow的父目录下，然后执行下面命令建立虚拟环境：
virtualenv --system-site-packages tensorflow
激活虚拟环境并安装tensorflow：
对于python27，则执行如下命令：
source ./tensorflow/bin/activate # If using bash
source ./tensorflow/bin/activate.csh # If using csh
(tensorflow)$ # Your prompt should change # Ubuntu/Linux 64-bit, CPU only:
pip install --upgrade https://storage./tensorflow/linux/cpu/tensorflow-0.6.0-cp27-none-linux_x86_64.whl # Ubuntu/Linux 64-bit, GPU enabled:
pip install --upgrade https://storage./tensorflow/linux/gpu/tensorflow-0.6.0-cp27-none-linux_x86_64.whl # Mac OS X, CPU only:
pip install --upgrade https://storage./tensorflow/mac/tensorflow-0.6.0-py2-none-any.whl
对于python3则执行如下命令：
source ./tensorflow/bin/activate # If using bash
source ./tensorflow/bin/activate.csh # If using csh
(tensorflow)$ # Your prompt should change
# Ubuntu/Linux 64-bit, CPU only:
pip install --upgrade https://storage./tensorflow/linux/cpu/tensorflow-0.6.0-cp34-none-linux_x86_64.whl # Ubuntu/Linux 64-bit, GPU enabled:
pip install --upgrade https://storage./tensorflow/linux/gpu/tensorflow-0.6.0-cp34-none-linux_x86_64.whl # Mac OS X, CPU only:
pip3 install --upgrade https://storage./tensorflow/mac/tensorflow-0.6.0-py3-none-any.whl
测试安装：
在终端执行如下命令进入python shell环境： python 在python shell环境中测试： >>> 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
>>>
如果遇到如下错误：
_mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: libcudart.so.7.0: cannot open shared object file: No such file or directory
那是你的CUDA安装配置不对： 且添加如下两行到你的 ~/.bashrc 文件
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"
export CUDA_HOME=/usr/local/cuda 如果遇到如下错误：
Python 2.7.9 (default, Apr 2 2015, 15:33:21)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

sudo ln -s /usr/local/cuda/lib64/libcudart.so.7.5 /usr/local/cuda/lib64/libcudart.so.7.0
sudo ln -s libcublas.so.7.5 libcublas.so.7.0
sudo ln -s libcudnn.so.4.0.4 libcudnn.so.6.5
sudo ln -s libcufft.so libcufft.so.7.0<br>sudo ln -s libcurand.so libcurand.so.7.0
