準備工作： win10 下， python3.7 安裝完成

問題#1 ：需要升級pip

C:\> pip install tensorflow
Collecting tensorflow
  Could not find a version that satisfies the requirement tensorflow (from versions: )
No matching distribution found for tensorflow
You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
 

升級pip

C:\> python -m pip install --upgrade pip
Collecting pip

問題#2 版本資訊不匹配？

C:\> pip3 install --upgrade tensorflow-gpu
Collecting tensorflow-gpu
  Could not find a version that satisfies the requirement tensorflow-gpu (from versions: )
No matching distribution found for tensorflow-gpu

 分析：

從 https://pypi.org/project/tensorflow-gpu/#files 查詢的結果分析，tensorflow-gpu 相關 python 版本為 cp27, cp33, cp34, cp35, cp36  當前所安裝的版本為37，沒有提供！    解除安裝 python3.7；安裝 python 3.6.7 併為其升級pip  

問題#3  pip 下載 tensorflow_gpu-1.11.0-cp36-cp36m-win_amd64.whl 失敗？

C:\Users\lsq> pip install tensorflow-gpu

手動下載 numpy-1.15.3-cp36-none-win_amd64.whl

本地安裝 numpy : 

pip install numpy-1.15.3-cp36-none-win_amd64.whl

完成後，繼續安裝 tensorflow-gpu :

pip install tensorflow_gpu-1.11.0-cp36-cp36m-win_amd64.whl

OK!

下個問題，如何檢驗 tensorflow-gpu 是否安裝正確？
