docker安装tensorflow环境遇到的问题与解决方案

docker安装 Tensorflow遇到问题i/o timeout.

docker: Error response from daemon: Get https://gcr.io/v1/_ping: dial tcp 64.233.188.82:443: i/o timeout.

Tensorflow 是Google的一个开源机器学习框架,中国大陆的用户在使用的时候往往需要爬过GFW墙,借助VPN。

依照Tensorflow的官方文档 在docker中安装Tensorflow的时候,国内的用户通常会报错,有的借助VPN可以解决,而有的不行。

(1)在docker成功安装完后,在终端命令行输入:

sudo docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow

(2)报错如下:

Unable to find image 'gcr.io/tensorflow/tensorflow:latest' locally
docker: Error response from daemon: Get https://gcr.io/v1/_ping: dial tcp 64.233.188.82:443: i/o timeout.
See 'docker run --help'.

主要原因还是因为GFW,在Github上有人提出过引起这个问题的原因,tensorflow/issues/1273,点击此链接

(3)关于这个,问题,我觉得最简单的办法是更换镜像的pull镜像库。也就是说,不是从Tensorflow给出的库(Google Cloud Platform)进行pull,而是用docker的库(docker hub)。

docker hub 中的tensorflow镜像介绍:

因此,在终端输入如下命令:

sudo docker run -it -p 8888:8888 tensorflow/tensorflow

只要你的docker是安装成功,能够pull镜像,那么基本会成功安装Tensorflow。我的运行输出如下:

Unable to find image 'tensorflow/tensorflow:latest' locally

因为这个镜像比较大,所以会需要一定的时间pull,耐心等待就好。

(4)打开一个新的命令终端进行测试是否安装成功:

首先,查看docker中有哪些容器/镜像存在

sudo docker ps -a

得到如下格式的输出:
这里写图片描述
注意到,第一个容器即是我们安装的tensorflow的镜像在运行的容器,其ID是53f212117a94

接着,进入容器:
替换我的这个53f212117a94 为你的,其他命令不变

sudo docker exec -i -t 53f212117a94 /bin/bash
  • 1

得到输入如下:

mingchen@mingchen-HP:~$ sudo docker exec -i -t 53f212117a94 /bin/bash
root@53f212117a94:/notebooks# 

看看python版本:

root@53f212117a94:/notebooks# python
Python 2.7.6 (default, Oct 26 2016, 20:30:19) 
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.

输出Hello, TensorFlow!:

>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
Hello, TensorFlow!

简单计算:

>>> a = tf.constant(10)
>>> b = tf.constant(32)
>>> print(sess.run(a + b))
42

测试结果显示,已成功在docker中安装Tensorflow。
