由于许多数据集下载命令需要Linux环境，而平时工作使用Windows设备，服务器设置代理又不方便，因此在Windows上通过WSL安装Linux子系统，并利用宿主机的系统代理使子系统能够访问公网。

安装WSL

Windows Subsystem for Linux(WSL)允许直接在Windows上运行GNU/Linux环境。
通过Microsoft Store下载，例如搜索Ubuntu，安装即可。
安装后，子系统的文件系统可直接访问：

设置WSL代理

初次运行时，需要设置账号密码，然后保存文件.proxyrc：

#!/bin/bash
host_ip=$(cat /etc/resolv.conf |grep "nameserver" |cut -f 2 -d " ")
export ALL_PROXY="http://$host_ip:10809"
export https_proxy="http://$host_ip:10809"
export http_proxy="http://$host_ip:10809"

其中端口10809仅为示意，需与宿主机的HTTP代理端口一致。

然后运行source .proxyrc

设置sudo环境

sudo命令默认不会继承环境变量。运行vim /etc/sudoers，在Defaults env_reset下方加入一行：

Defaults env_keep += "http_proxy https_proxy ftp_proxy all_proxy no_proxy"

将Windows脚本转化为Unix脚本

出现类似scripts/download_dtu_ground_truth.sh: line 2: $'\r': command not found的问题，因为Windows的换行为\r\n，而Unix为\n。

sudo apt update
sudo apt install dos2unix
sudo dos2unix [filepath]

至此设置完成。

CUDA out of memory

• Kill dead processes;

# replace '*' with 0, 1, ..., find running $PID
lsof /dev/nvidia*
kill -9 $PID

• reload Nvidia driver;

# Reload without rebooting
# close display management
systemctl isolate multi-user.target

# disable nvidia driver（if returns relying on xxx，rmmod them as well）
rmmod nvidia

# load nvidia driver
modprobe nvidia

# restart display management
systemctl start graphical.target

Or

sudo apt install nvidia-modprobe

• Reboot.

Docker Run without Root

sudo chmod a+rw /var/run/docker.sock

Docker Nvidia Runtime

Install Nvidia Container Runtime

curl -s -L https://nvidia.github.io/nvidia-container-runtime/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list
sudo apt-get update
sudo apt-get install nvidia-container-runtime

Modify Config

sudo vim /etc/docker/daemon.json

# /etc/docker/daemon.json
{
    "runtimes": {
        "nvidia": {
            "path": "nvidia-container-runtime",
            "runtimeArgs": []
        }
    },
    "default-runtime": "nvidia"
}

Reload docker

sudo systemctl daemon-reload
sudo systemctl restart docker

Mount WebDav as 777

sudo apt install davfs2
sudo mount -t davfs http://your-url-of-webdav/ /your/mount/point/path -o uid=$YOURUID,gid=$YOURGID,dir_mode=0777,file_mode=0777

Mount Disk as 777

# find target disk, like /dev/sda or /dev/sda1
sudo fdisk -l

# mount once. file permission is (777-umask)
sudo mount /dev/your-disk /your/mount/point/path -o umask=000

# mount as startup
# find $UID, like 3e395c6c-8e04-4bd6-93cd-1152fa797262
sudo blkid /dev/your-disk
sudo vim /etc/fstab

# /etc/fstab
# add line
UID=$UID /your/mount/point/path ext4 auto,exec,user,rw,umask=000 0 0
