TensorFlow至今釋出已經一年多了，以前都是在linux上玩，前兩天TensorFlow的windows版本面世了。忍不住就搗鼓裝了下，其實在網速很好的情況下還是很方便安裝的。
截止到今日（2016.12.6）只可以在python3的環境下安裝，如下圖所示：

我電腦安裝有python3.5.2，和Anaconda3，是沒問題的。如果網速不好的話，直接用pip安裝些依賴包會很費時間，甚至中斷，這裡推薦看需要哪些依賴包，然後直接在國內的映象（在simple資料夾裡）上下載最新版，然後用電腦本地安裝：

好了，開始安裝：
1. 命令：

C:\Windows\system32>pip install --upgrade https://storage.googleapis
 
.com/tensorflow/windows/gpu/tensorflow_gpu-0.12.0rc0-cp35-cp35m-win_amd64.whl

報錯：由於Anaconda3-4.2.0自帶的是setuptools 27.2.0版本。查了下，現在最新版本是30.2.0。需要升級setuptools的版本。（需要說明的是，如果你不是anaconda，而是直接配置的python3的話， 就不會有下面的問題了，如果網速快的話，直接就可以裝好了，如果不快，通過自行在上面提到的映象中下載依賴包也可以解決的）

1. 命令：用pip升級setuptools

C:\Windows\system32>pip install setuptools --upgrade

依舊不行：

Installing collected packages: setuptools
  Found existing installation: setuptools 27.2.0
Cannot remove entries from nonexistent file d:\program files\anaconda3\lib\site-packages\easy-install.pth

換做使用conda升級

conda update setuptools

還是不行。

1. 命令：那麼就用conda remove掉setuptools

C:\Windows\system32>conda remove setuptools

無法移除

Fetching package metadata .........
Solving package specifications: ..........


RemoveError: Remove Error: Error: this 'remove' command cannot be executed because it
would require removing 'conda' dependencies

1. 命令：嘗試用conda定向下載來源來升級（國內映象）：

C:\Windows\system32>conda update --channel http://pypi.doubanio.com/packages/b8/cb/b919f52dd81b4b2210d0c5529b6b629a4002e08d49a90183605d1181b10c/setuptools-30.2.0-py2.py3-none-any.whl#md5=8749d518ffd7e268037af5178f4f9778 setuptools

不行：

Fetching package metadata .........

CondaHTTPError: HTTP 500 None
for url <None>

An remote server error occurred when trying to retrieve this URL.

A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request.  The problem may be spurious, and will resolve itself if you
try your request again.  If the problem persists, consider notifying the maintainer
of the remote server.

1. 命令：考慮用conda升級到指定版本：

C:\Windows\system32>conda upgrade setuptools=30.2.0

依舊不行：

CondaValueError: Value error: version specifications not allowed with 'update'; use
    conda update  setuptools         or
    conda install setuptools=30.2.0

1. 命令：考慮用conda安裝指定版本：

C:\Windows\system32>conda install setuptools=30.2.0

錯：

Fetching package metadata .........
Solving package specifications: .


PackageNotFoundError: Package not found: '' Package missing in current win-64 channels:
  - setuptools 30.2.0*

You can search for packages on anaconda.org with

    anaconda search -t conda setuptools

意思就是忽略已經安裝的setuptools版本，直接安裝最新的版本。

1. 命令：

C:\Windows\system32>pip install setuptools --ignore-installed

好了！

1. 命令：再次安裝tensorflow：

C:\Windows\system32>pip install --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-0.12.0rc0-cp35-cp35m-win_amd64.whl

大功告成！
