win10 +keras +gpu

前段时间自己写了个配置keras 的cpu过程，但是这几天换了一台新的神州，迫不及待的玩一下gpu版的。当然过程比较复杂，在宿舍调了一天才弄好。先说一下各个版本吧

cuda -8.0.61
cudnn5.1
anconda4.2
python3.5
tensorflow版本（重要）

当然，前两布比较简单，都是默认安装，然后把cudnn解压到v8.0下，然后吧bin和x64/lib添加到环境变量。这个大部分都没问题。
然后 pip install tensorflow 结果出现一大堆问题。

Failed to load the native TensorFlow runtime.

经过查阅，有说解决方案安装vc++2015 的，还有等等，不过我是没装好，然后偶然情况下发现了这个

pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.2.0-cp35-cp35m-win_amd64.whl

果断尝试，其实当时已经绝望了，没想到OK了，我这里可能有两个原因，一是tensorflow 的版本问题，而是装完vc++后重启。反正就是OK了，很开心，然后安装keras的前奏，这里去某个网站（前文提到过）下载numpy+mkl ，scipy，安装。然后从豆瓣镜像下载（-i代表pip源，-trusted是要添加信任，否则会报提示）

pip install keras -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

果断从keras跑两个程序玩玩。
