之前有装pytorch的过程，但是不少文章的模型用的tensrflow。。就是就pip install tsnsorflow下载了该package，在运行环境测试代码的时候报错缺少dll

看了些帖子说tf2.3需要cuda10.1.。。。10.2和10.0都不好使。。。于是要装回10.1.。。are u kidding me???下个旧版的而且不支持新版？？？一个10.1就2.5g。。。还要装10.2的那个我还没有试过
于是我就想着吧，既然确实dll，那我直接下载dll不就行了吗，于是我下载了cudart64_101.dll，按照别的帖子说的路径“C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.x\bin”,问题在于我的cuda 10.2没有发现NVIDIA GPU Computing Toolkit这个文件夹。。。于是我把这个刚下载的ll放在了C:\Windows\System32，重新运行了示例程序，Yes！！
这里附上下载链接

打开我的Anaconda的Tensorflow环境，运行就出来了。。。。。
