win10 tensorflow安装教程 超详细 小白手把手教程

一.安装anaconda3(最好安装4.2.0版本)

网址：点击打开链接

选择anaconda3 4.2.0下载

我之前安装过anaconda2，所以网上查找了很多方法，在下载完成anaconda3后，一直下一步，当出现安装路径的时候，要注意：

把anaconda3安装在anaconda2/envs下，先选择这个路径，如下图：

在此一定要注意，不要新建文件夹，否则会出现如下问题：

此时应该删除anaconda3这个空文件夹，在D:\Anaconda2\envs\后面手打Anaconda3\，这样就可以顺利安装了。

然后将anaconda3、Anaconda3\Scripts、Anaconda3\Library\bin的路径添加到用户变量PATH中。

二.VS2015企业版

安装过程很慢，耐心等待。

三.pip安装

这一步很关键，往往网上说的都是直接更新pip,但是往往出现诸如以下的错误：

C:\Users\Administrator>pip install --upgrade pip
ERROR: To modify pip, please run the following command:

d:\anaconda2\python.exe -m pip install --upgrade pip

我以为是我之前安装过anaconda2，所以默认的是anaconda2，故将目录跳转到anaconda3下，结果如下：

D:\Anaconda2\envs>pip install --upgrade pip
ERROR: To modify pip, please run the following command:

d:\anaconda2\python.exe -m pip install --upgrade pip

还是出现了错误。后来我想是不是需要进入anaconda3根目录文件夹下才可以进行下载，故cd anaconda3：

D:\Anaconda2\envs\Anaconda3>pip install --upgrade pip
ERROR: To modify pip, please run the following command:

d:\anaconda2\python.exe -m pip install --upgrade pip

还是报错！然后我尝试使用调用python的exe文件进行安装，结果：

D:\Anaconda2\envs\Anaconda3>python.exe pip install --upgrade pip

python.exe: can't open file 'pip': [Errno 2] No such file or directory

还是报错！因为看介绍文章说，这一步可以跳过，所以我想直接下一步，试试可不可以，结果：

D:\Anaconda2\envs\Anaconda3>pip install tensorflow
Collecting tensorflow
  Could not find a version that satisfies the requirement tensorflow (from versions: )

No matching distribution found for tensorflow    

我重新尝试在envs目录下更新pip：

D:\Anaconda2\envs>pip install --upgrade

ERROR: You must give at least one requirement to install (see "pip help install")

这个时候出现了很关键的一条语句，说我至少应该安装一个需求，查看help后，没看到什么有用信息。这个时候我想到anaconda2切换到3再进行操作，于是，我用：

D:\Anaconda2\envs\Anaconda3>activate anaconda3

在3下进行：

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install --upgrade pip
Cache entry deserialization failed, entry ignored
Collecting pip

Installing collected packages: pip
  Found existing installation: pip 8.1.2
    Uninstalling pip-8.1.2:
Exception:

    os.rename(src, real_dst)

During handling of the above exception, another exception occurred:


Traceback (most recent call last):
  File "D:\Anaconda2\envs\anaconda3\lib\site-packages\pip\basecommand.py", line 215, in main
  File "D:\Anaconda2\envs\anaconda3\lib\site-packages\pip\commands\install.py", line 317, in run

    os.unlink(src)

PermissionError: [WinError 5] 拒绝访问。: 'd:\\anaconda2\\envs\\anaconda3\\scripts\\pip.exe'

还是有错，接着我直接安装tensorflow：

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install tensorflow

Cannot open D:\Anaconda2\envs\anaconda3\Scripts\pip-script.py

还是报错，找不到pip-script.py这个文件，搜索后发现需要先安装pip，汗！于是在此目录下，easy_install pip进行了下载：

(anaconda3) D:\Anaconda2\envs\Anaconda3>easy_install pip

然后pip install dicom：

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install dicom

然后才进入我们一开始的那一步

pip install --upgrade pip

终于可以了！

四.安装tensorflow

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install --upgrade pip

ERROR: To modify pip, please run the following command:
D:\Anaconda2\envs\anaconda3\python.exe -m pip install --upgrade pip

需要用python 进行更新

(anaconda3) D:\Anaconda2\envs\Anaconda3>python.exe -m pip install --upgrade pip

然后下载安装tensorflow

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install tensorflow

你会发现出现很长的红字报错

我们通过如下命令查看：

(anaconda3) D:\Anaconda2\envs\Anaconda3>conda config --show

会发现

网址是https://conda.anaconda.org/，因为是国外网站，所以下载网速很慢，经常出现下载超时的提醒，尝试多次会发现一直都不能成功，我们可以采用修改pip源的方法，把地址改为阿里的：

(anaconda3) D:\Anaconda2\envs\Anaconda3>pip install tensorflow -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com

很快下载完成。成功！

接下来对安装好的tensorflow进行测试：

(anaconda3) D:\Anaconda2\envs\Anaconda3>python
Python 3.5.2 |Anaconda 4.2.0 (64-bit)| (default, Jul  5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
>>> a = tf.constant("hello world")
>>> sess = tf.Session()
2018-05-30 19:34:34.977362: I T:\src\github\tensorflow\tensorflow\core\platform\cpu_feature_guard.cc:140] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
>>> print(sess.run(a))
b'hello world'
>>> exit()

成功！
