注：安装nvidia驱动的说法蛮多:

尽量使用ppa安装
使用最新版本可能会有问题，使用nvidia-smi能测试是否nivia驱动正常
从官网查询nvidia驱动的版本，例如t440p的是GT 730M, 官网查询它仅能使用418版本 - https://www.nvidia.com/Download/index.aspx?lang=en
又尽量不要使用官方版本，从ppa上安装418版本　, 见：　https://blog.csdn.net/quqi99/article/details/54950383
如果ubuntu能进CLI但不能进GUI, 很有可能是nvidia驱动造成的(查询lightdm/gdm3, gpu-manager服务确认是否是因为找不着GPU造成的, 一个例子－https://zhhuabj.blog.csdn.net/article/details/54950383）

sudo add-apt-repository multiverse
sudo apt update
sudo apt install -y libvulkan1 libvulkan-dev mesa-vulkan-drivers
#sudo add-apt-repository ppa:graphics-drivers/ppa  #Use latest version
sudo lshw -c display             #By default, the opensource nouveau driver is being used for Nvidia card.
sudo ubuntu-drivers devices      #List available driver for your Nvidia card from the default Ubuntu repo.
#sudo ubuntu-drivers autoinstall  #Or run: sudo apt install nvidia-driver-418
# t440p only support 418 version
sudo apt install nvidia-driver-418
#sudo apt purge nvidia-*
#如果总是报＂Failed to initialize NVML: Driver/library version mismatch＂，可能是purge nvidia之后没有重启所致
# 重启后用'lsmod |grep nvidia' 确认为空
sudo shutdown -r now
sudo lshw -c display
prime-select querysudo prime-select intel
sudo prime-select nvidia
# reboot again, then nvidia-smi will have the output

1, install nvidia driver above

$ modinfo nvidia |grep version
version:        470.129.06$ lsmod |grep -i nvidia
nvidia_uvm           1175552  0

|  GPU   GI   CI        PID   Type   Process name                  GPU Memory |

2, install cuda-drivers

sudo wget -O /etc/apt/preferences.d/cuda-repository-pin-600 https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/7fa2af80.pub
sudo add-apt-repository "deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv A4B469963BF863CC
sudo apt install cuda-drivers=470.129.06-1

3, make sure libcuda.so.1 is there

sudo apt-file search -x '/libcuda.so.1$'
$ sudo apt-file search -x '/libcuda.so.1$' |grep 470
libnvidia-compute-470: /usr/lib/x86_64-linux-gnu/libcuda.so.1
libnvidia-compute-470-server: /usr/lib/x86_64-linux-gnu/libcuda.so.1

4, install tensorflow

#https://www.tensorflow.org/install/gpu
sudo pip3 install tensorflow
sudo apt-get install --no-install-recommends cuda-11-0 libcudnn8=8.4.1.50-1+cuda11.6 libcudnn8-dev=8.4.1.50-1+cuda11.6

5, test

import tensorflow as tf
print(f"Num GPUs: {tf.config.list_physical_devices('GPU')}")
