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。
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 latest: Pulling from tensorflow/tensorflow 862a3e9af0ae: Pull complete 6498e51874bf: Pull complete 159ebdd1959b: Pull complete 0fdbedd3771a: Pull complete 7a1f7116d1e3: Pull complete f22ce26e7804: Pull complete 80e54362977d: Pull complete 6bf17916f3f1: Pull complete cbb2cc9179cb: Pull complete 4f976cd18afd: Pull complete 31ba02bae790: Pull complete e26c94fb0976: Pull complete Digest: sha256:feedf027da0d525300dc73e433b4ade2147c6a408756cdd9846fd37b40929f8a Status: Downloaded newer image for tensorflow/tensorflow:latest [I 03:19:59.901 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret [W 03:19:59.981 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption.

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: 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
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
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。 |
