Windows下Anaconda环境安装Tensorflow

来源：互联网发布：钣金展开软件下载编辑：程序博客网时间：2024/05/14 03:54

1. 安装好Anaconda后请确保以下几个路径已经添加到Window系统环境变量的path中

C:\ProgramData\Anaconda3 //C:\ProgramData\Anaconda3是我安装Anaconda的路径

C:\ProgramData\Anaconda3\Scripts //Anaconda路径的Scripts子文件夹

C:\ProgramData\Anaconda3\Library\bin

2. 如下步骤，conda会帮你安装好所有相关软件包，本方法适合网速较快的朋友，如果网速较慢，建议直接用另一种方法3

C:\>conda create -n tensorflow

C:\>activate tensorflow

(tensorflow) C:\>python -m pip install --upgrade pip
Requirement already up-to-date: pip in c:\programdata\anaconda3\lib\site-packages

(tensorflow) C:\>anaconda search -t conda tensorflow

To install this package with conda run:
conda install --channel https://conda.anaconda.org/anaconda tensorflow-gpu

//选择安装最新GPU版本，你也可以选择安装CPU版，国内连接这个网站比较慢，也可以用清华大学镜像网站

//可以配置清华大学镜像网址

(tensorflow) C:\>conda config --addchannels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

(tensorflow) C:\>conda config --setshow_channel_urls yes

(tensorflow) C:\>conda install --channel hhttps://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ tensorflow-gpu

//用anaconda主机下载，可能比较慢

另一种方法：

3 安装CPU版本请跳过3.1 3.2 3.3

下载 3.1 3.2

3.1

CUDA® Toolkit 8.0. For details, see NVIDIA's documentation

3.2 需要用邮箱注册成Nvdia开发者下载，最好用国外邮箱，国内有些邮箱可能收不到激活邮件。

注意现在tensorflow还不支持最新的cuDNN7.0，一定要下载cuDNN V6.0 for cuda8.0

cuDNN v6 or v6.1. For details, see NVIDIA's documentation

3.3

安装完3.1后，确认cuda toolkit的路径已经在系统环境变量path中，不在请手动添加 toolkit的安装路径如C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0到系统环境变量

将3.2文件解压后的三个文件夹拷贝到C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0

3.4

cmd指令窗口运行

C:\>conda create -n tensorflow
C:\>activate tensorflow

//安装CPU版本用这个指令

(tensorflow) C:\>pip install --ignore-installed --upgrade tensorflow

//如果安装GPU版本用这个指令

(tensorflow) C:\pip install --ignore-installed --upgrade tensorflow-gpu

4 确认tensorflow正确安装

C:\>python

输入如下代码

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

当看到如下打印，即正确安装了

b'Hello, TensorFlow!'
>>>
