之前下载了cuda11.1想要使用tensorflow的gpu版本，不料调试的时候出了问题，使用tf.test.is_gpu_available()命令测试的时候出现了如下错误：
错误日志：
WARNING:tensorflow:From <ipython-input-2-17bb7203622b>:1: is_gpu_available (from tensorflow.python.framework.test_util) is deprecated and will be removed in a future version.
Instructions for updating:
Use `tf.config.list_physical_devices(‘GPU‘)` instead.

使用的版本如下：
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
上述错误也表示gpu版本并不能使用，但是看到了错误
字面意思就是少cusolver64_10.dll的动态链接库，少库肯定要去文件里找
打开自己的cuda安装目录，依次打开../NVIDIA GPU Computing Toolkit\CUDA\v11.1\bin,找到问题所在了
后缀名字是11，但是我们需要的是10，尝试更改了文件为cusolver64_10.dll，运行
没想到会是这个问题
呵呵，你妹的

网上也有说版本不兼容的问题，降版本是一定可以解决问题的，但我的习惯是下载任何东西都尽量保持最新。。。
看后面能不能遇见啥新问题吧。。
