【Deepin 20系统+Tensorflow 2】Linux系统解决Could not load dynamic library ‘libcudart.so.10.0‘

问题

环境

Deepin 20系统： Debian OS
NVIDIIA 驱动: NVIDIA-SMI 455.45.01 Driver Version: 455.45.01
nvidia-smi 显示cuda版本: CUDA Version: 11.1
安装的Cuda版本：11.1
Tensorflow2.0

在使用tensorflow2跑程序时，GPU没有利用起来，通过代码查看GPU使用情况，输出日志如下

import tensorflow as tf
print(tf.test.is_gpu_available())

输出日志

日志说明：正在寻找CUDA 10.0。 但是我的CUDA版本是11.1，不能使用CUDA 11.1或CUDA 11.2替代它。 仅仅需要去官网下载CUDA10.0和对应的cudnn安装即可，不需要更改NVIDIA驱动。并且注意，根据自己的文件CUDA路径，进行相应的环境变量的配置

步骤
（1）CUDA+CuDnn安装过程参考本人另一篇博客Deepin 20系统安装CUDA+cudnn
（2）更改CUDA环境变量参考本人另一篇博客Deepin 20系统切换CUDA版本
