win10 安装tensorflow 报错“ERROR: Failed building wheel for wrapt”解决办法

今天打算在win10下安装cuda和tensorflow-gpu, 用pip install tensorflow-gpu安装时出现以下错误：

C:\WINDOWS\system32>pip install tensorflow-gpu
Collecting tensorflow-gpu

。。。。。。。。。。。。。。。。。。。。
Building wheels for collected packages: wrapt
Building wheel for wrapt (setup.py) … error

Running setup.py clean for wrapt

解决办法：
1、下载对应python版本的wraptxxx.whl：https://www.lfd.uci.edu/~gohlke/pythonlibs/#wrapt
2、安装： pip install 刚刚下载whl文件绝对路径
3、然后再重新安装tensorflow，成功。
