还在为以下问题烦恼？
raise OSError('CUDA_HOME environment variable is not set. ’
OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.

conda install cudatoolkit －c conda-forge 找不到指定版本？
找不到cusolver.h
等等等等
。。。

nvidia现在官方提供了一键安装所有cuda依赖，再也不需要自己去单独安装cudatoolkit cudatoolkit－dev等等依赖了
命令如下，记得指定版本
conda install nvidia::cuda

其他问题

1. docker安装完后只能通过root运行，让普通用户也能运行docker
   sudo usermod -aG docker $USER
   来源vscode

2. ubuntu20 卸载了docker-desktop,重新安装docker后出现普通用户用不了docker的问题，错误显示如下
   Cannot connect to the Docker daemon at unix:///home//.docker/desktop/docker.sock. Is the docker daemon running?
   直接删除
   rm -r /home/$USER/.docker
   来源stackoverflow

3. 修改docker port映射
   You can change the port mapping by directly editing the hostconfig.json file at /var/lib/docker/containers/[hash_of_the_container]/hostconfig.json

4. vnc 初始化错误
   输入 vncserver 报错
   perl: warning: Setting locale failed.
   perl: warning: Please check that your locale settings:
   LANGUAGE = (unset),
   LC_ALL = (unset),
   LANG = “en_US.UTF-8”
   are supported and installed on your system.
   perl: warning: Falling back to the standard locale (“C”).
   vncserver: The USER environment variable is not set.
   解决位置问题：reference
   export LC_ALL=C
   解决vncserver: The USER environment variable is not set. 问题：reference
   USER=yourusername vncserver
   ？使用非root来运行vncserver

如果 view only passward设错了通过下面这个命令来修改
vncpasswd

新增用户 ：
sudo adduser newuser
ubuntu 新增user后，使他可以用sudo：
usermod -aG sudo limstorm
或

Open file

su root 
nano /etc/sudoers
Then add the user below admin user like below syntax.

user_name ALL=(ALL)  ALL

docker安装gui界面

注意：
解决locale问题
apt-get install language-pack-en-base

解决 Failed to close file descriptor for child process (Operation not permitted) 问题

按照mediapipe官方docker运行，安装opencv会有问题：需要修改
libdc1394-22-dev ==> libdc1394-dev
