tensorflow在centos安裝

1.安裝python2.7

下載python-2.7.5.tar.gz文件，

tar -xzvf python-2.7.5.tar.gz

cd python-2.7.5

./configure --prefix=/usr/local/python2.7  --enable-unicode=ucs4

make && make install

建立軟連接，使系統默認的python指向python2.7

mv /usr/bin/python /usr/bin/python2.6.6.old

ln -s /usr/local/python2.7/bin/python   /usr/bin/python

已經安裝完成python的安裝或升級的全部操作了，我們再來看一下現在的python的版本：

# python -V

Python 2.7.5

雖然現在python已經安裝完成，但是使用yum命令會有問題——yum不能正常工作：

這是因爲yum默認使用的python版本是2.6.6，到哪是現在的python版本是2.7.5，故會出現上述問題，只需要該一下yum的默認python配置版本就行了：

#vi /usr/bin/yum

將文件頭部的#!/usr/bin/python改爲

#!/usr/bin/python2.6

2. 安裝setuptools

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.3.tar.gz
tar zxvf setuptools-3.3.tar.gz
cd setuptools-3.3
python setup.py build
sudo python setup.py install

3.安裝pip

從pip官網 https://pypi.python.org/pypi/pip 下載pip的源代碼
#解壓
tar -zxvf pip-1.5.5.tar.gz 
cd pip-1.5.5
#安裝
sudo python setup.py install

4.安裝tensorflow

# 僅使用 CPU 的版本
pip install https://storage.googleapis.com/tensorflow/linux（小寫）/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

如果numpy下載不下來，可以使用pip install numpy 安裝

# 開啓 GPU 支持的版本 (安裝該版本的前提是已經安裝了 CUDA sdk)
pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

5.測試：

運行 TensorFlow
打開一個 python 終端:
$ 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
>>>

yum install gcc

wget http://ftp.gnu.org/pub/gnu/glibc/glibc-2.17.tar.xz
xz -d glibc-2.17.tar.xz
tar -xvf glibc-2.17.tar
cd glibc-2.17
mkdir build
cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin  
make && make install
需要等大概10分鐘。
