Tensorflow安装步骤

本文主要包括如下几个部分:

• docker 安装
• pip安装
• 编译安装
• 问题
• 参考文献

1. docker安装

下载官方的镜像，即可使用。不过不推荐，因为这个Tensorflow的模块是在Docker内的，也就是你编译的时候，需要进入Docker镜像的内部进行使用。也就是import tensorflow as tf命令在你的Docker外是无法生效的。使用IDEA这样的调试工具调试的时候，会略微有点蛋疼。

但是，学习Tensorflow语法的话可以使用相对应的Jyter这个工具平台进行学习，非常方便。

分享一个很好的TensorFlow的Docker镜像和Docker仓库:

• github 项目: https://github.com/caicloud/tensorflow-tutorial
• docker 仓库 docker pull cargo.caicloud.io/tensorflow/tensorflow:0.12.0
• 启动 docker run - it cargo.caicloud.io/tensorflow/tensorflow:0.12.0 -p 8888:8888 -p 6066:6066
• 8888为Jupyter编辑器,docker logs 会看到如下的内容,里面包含密码。访问http://localhost:8888即可进入Jupyter编辑器。6066为TensorBoard。

[root@rhel6 ~]# docker logs 45fd0affc965[I 03:19:24.125 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret[W 03:19:24.246 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption.

2. pip安装

使用pip前，先确定安装了python。
在命令行输入python/python3，即可判断你是否全局配置了python程序。

MAC OSX系统不推荐使用官方自带的Python2.7.3程序，因为那边有很多的程序是被写保护的。

Ubuntu/Linux # 仅使用 CPU 的版本$ pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl# 开启 GPU 支持的版本 (安装该版本的前提是已经安装了 CUDA sdk)$ pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whlMac OS X # 当前版本只支持 CPU$ pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whlDocker$ docker run -it b.gcr.io/tensorflow/tensorflow

3. 编译安装

不推荐

4. 问题

使用pip安装基本没有什么问题，但是需要注意的是。千万不要使用Mac自带的python，那个地方是写保护的。

报错信息如下:

解决办法: brew install python，使用新的python即可。
