本来安装tensorflow-gpu是一句话的事情，但因为版本变动，今天安装遇到很多麻烦，简单记录

​ 之前是装了tensorflow-gpu==2.6.0的版本的，但后来在这个环境中安装了sionna，这个可恶的库居然直接卸载了我的tensorflow-gpu==2.6.0，安装了满足它要求的13版本tensorflow，而且还是cpu版本的，安装之前都没问我要不要安装，真可恶啊，导致我不得不重新安装tensorflow-gpu

​ 首先创建3.9版本python环境，然后conda install tensorflow-gpu==2.6.0安装，记得科学上网

​ 安装完后，再conda install keras==2.6.0安装keras

​ 这时候已经自动安装了cudatoolkit、cudnn、tensorflow-gpu、keras、numpy等

​ 你以为行了？

​ print(tf.__version__)报错，说是numpy不再有object属性，那可以推断numpy版本过高，pip卸载numpy重新安装低版本即可（后来知道，只需要不停的降低版本，就能试出来符合要求的版本）

​ 但是，重新安装numpy后又会报各种不兼容问题，其实这个问题我们不用管，当我去管它，又会出现各种各种的兼容问题，所以直接不管！具体原因我推测是那些提示版本不兼容的包，实际我们很难使用到

​ 列出一个tensorflow-gpu==2.6.0能用的版本软件：
