python3.7的tensorflow-gpu2.0环境安装CUDA和cuddn，解决cudart64_101.dll not found问题

满心欢喜的以为用anaconda3 5.3.1装好了tensorflow-gpu
在vscode开用的时候，一盆冷水扑过来

【本机环境】
Python 3.7.0
tensorflow-gpu 2.1.0
keras 2.3.1
cudnn-10.0-windows10-x64-v7.6.4.38
cuda_10.0.130_411.31_win10

看到网上说tensorflow2.0对应的cuda版本是10.0，绝对不能下载错，那我就试试吧
1、安装CUDA
下载地址：https://developer.nvidia.com/cuda-10.0-download-archive?target_os=Windows&target_arch=x86_64&target_version=10&target_type=exelocal

安装的时候关联了VScode

2、cuDNN的安装
先去官网注册,注册真慢到想哭，还要进行recaptcha测试，不经意间进行了一次图灵测试，和人工智能鼻祖进了一步

帮大家避坑，直接分享网盘

3、环境变量设置
到环境变量中的系统变量的path下默认有第1和第2个增加第3和第4个

C:\Users\shan-dell>nvcc -V

4、仍然存在问题

2020-02-27 16:25:15.357944: W tensorflow/stream_executor/platform/default/dso_loader.cc:55] Could not load dynamic library ‘cudart64_101.dll’; dlerror: cudart64_101.dll not found
按网上的说说法备份一个cudart64_100.dll，改一个cudart64_101.dll

顺利完成
