tensorflow安装(CentOS)

>yum install python-pip python-dev python-virtualenv

>virtualenv --system-site-packages ~/tensorflow

>source ~/tensorflow/bin/activate -----开启virtualenv

$export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0rc0-cp27-none-linux_x86_64.whl

$pip install --upgrade $TF_BINARY_URL

注：如果出现<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)>异常，表示当前python版本对https支持有问题，暂时解决办法是上一步的https修改为http

测试

$python

>>>import tensorflow as tf

>>>hello = tf.constant('Hello, TensorFlow!')

>>>sess = tf.Session()

>>>print(sess.run(hello))

>>>a = tf.constant(10)

>>>b = tf.constant(32)

>>>print(sess.run(a + b))

$deactivate ------关闭virtualenv

----------------------------------------------

以上是以yum 的方式进行安装，这些我们就可以自己写python代码import tensorflow了，但是tensorflow的源码中有很多example，所以我们最好把tensorflow的源码下载下来

>mkdir works

>cd works

>git clone https://github.com/tensorflow/tensorflow --如果没有安装git，yum install git

>cd tensorflow

>git status
