TensorFlow DeepLab教程初稿-tensorflow gpu安装教程
商务合作，科技咨询，版权转让：向日葵，135—4855__4328，xiexiaokui#qq.com
Summary: DeepLab需要1.10以上版本。
本日志详细记录在两台不同笔记本电脑安装/更新 TensorFlow-GPU的具体过程
这是本人第3次，4次安装tf，这两次是gpu版。
第一次是安装cpu版，第二次是在python2.7 arcpy环境下安装32位 tf，但不能运行。第三次安装成功，但电脑配置过低，只能使用cpu功能；第四次安装成功，可以正确运行，使用gpu。

Reinstall cudnn
安装cuDNN
官网下载好后可以直接解压文件夹。然后将这个文件夹下的文件按照如下操作复制到CUDA路径下：
Copy <installpath>\cuda\bin\cudnn64_*.dll to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\ v10.0\bin.
Copy <installpath>\cuda\ include\cudnn.h to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\ v10.0\include.
Copy <installpath>\cuda\lib\x64\cudnn.lib to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\lib\x64.

总结
在anaconda3.6安装最新版（未指定版本）tf-gpu，失败。因为没有提示具体错误，难以分析具体原因，所以拟在别的位置的python上重新安装。
失败的原因可能是在本python下已经安装了tf cpu '1.12.0'
找到vs安装的python3.7，添加环境变量和权限后，更新pip命令，未指定版本， '1.14.0'，安装成功，发现下载速度很快，一会儿就安装好了，但不能正确运行。
之后换位置安装好，但gpu版本太低，无法应用gpu加速。
最后换电脑安装，终于成功。
结论：
1. 查看gpu-cuda计算能力，是否大于3.5
2. 如果python安装c盘，需要添加权限
3 更新pip
4. 安装tf-gpu，目前最新版为1.14.0
5.安装cuda和cudnn，需要完全核定版本，这一步可以根据运行tf的结果来确认版本。
