docker环境下安装tensorflow
下载tensorflow 镜像并运行 [root@Ieat1 ~]# docker run -d --name tensorflow -it -p 8888:8888 tensorflow/tensorflow ff716bcb8642e258eb7007f3f0c6756a82998d2844df8b374df85c9faf1b0629 通过观察发现新建的notebook都在容器的/notebooks目录下，为了使notebook不丢失，我们可以把它放在宿主机的目录上，比如/data/tensorflow/notebooks，启动时指定卷 docker run -d --name tensorflow -v /data/tensorflow/notebooks:/notebooks -it -p 8888:8888 tensorflow/tensorflow 查看docker日志，发现提示我们访问地址 http://127.0.0.1:8888/?token=061bdda51d27eaab82049d1eda42bd63381a4c4d33eaee67 [root@Ieat1 ~]# docker logs -f tensorflow [I 06:11:01.349 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret [W 06:11:01.372 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption.
