安装TensorFlow的步骤 1 安装 PIP2 安装 TensorFlow 安装完成后测试

安装TensorFlow的步骤

从官网上面可以看到TensorFlow的安装方式主要是如下几种：

Pip install: Install TensorFlow on your machine, possibly upgrading previously installed Python packages. May impact existing Python programs on your machine. Virtualenv install: Install TensorFlow in its own directory, not impacting any existing Python programs on your machine. Anaconda install: Install TensorFlow in its own environment for those running the Anaconda Python distribution. Does not impact existing Python programs on your machine. Docker install: Run TensorFlow in a Docker container isolated from all other programs on your machine. Installing from sources: Install TensorFlow by building a pip wheel that you then install using pip.

由于种种原因，最终我选择在ubuntu的虚拟机上面利用Pip install 的方式来进行安装 TensorFlow 的CPU版本。同时还需要就安装Pip的安装包。

1.1. 安装 PIP

下载从python (2.7) 的官网下载Pip的 安装包 学习 用tar 解压缩,并且进入到解压目录中

$ sudo python setup.py install

完成pip的安装后准备安装TensorFlow。

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

1.2. 安装 TensorFlow

安装 TensorFlow 需要从 storage.googleapis.com/tensorflow 下载一些东西，貌似需要科技上网

完成后就会显示上面红字的这句话，再往上看就可以看到总共下载来上面地四个进度条的东西。

安装完成后测试
