国内下载国外数据集（库）方案整理

在科研过程中常常需要下载国外数据集，但鉴于国内网络环境往往无法访问。本文总结了一些下载方案，所介绍的方案适用于合法访问国际互联网情形，或特殊渠道流量不够的情况。

方案一

可以试试直接用迅雷能否下载，试试百度云盘的离线下载能否成功.

方案二

在谷歌colaboratory上将文件下载至谷歌云盘,再使用multcloud关联谷歌云盘,可以实现关闭特殊渠道方式下载.(multcloud网络不稳定)

方案三(推荐)

在阿里云上申请一个入门级的境外服务器(存储空间够即可，无带宽要求；若想使用图形界面需满足1个CPU（2.5GHz），1G内存；仅用命令行则选用最低配置即可。可以选择只购买一周。),或者用谷歌colaboratory（传大文件不稳定），先下载，再用命令行上传至百度云盘,参考 https://www.jianshu.com/p/11f071e1f7fe

sudo pip install bypy
bypy info
bypy upload filename -v

如果遇到以下问题

<W> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<W> WARNING: Can't detect the system encoding, assume it's 'UTF-8'.
Files with non-ASCII names may not be handled correctly.
<W> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<W> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<W> Encoding for StdOut: ANSI_X3.4-1968
<W> !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

命令行输入

locale-gen en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

可以考虑安装图像界面（游客模式数据会在登出后删除，运行卡顿。能流畅运行的配置方案：1个CPU（2.5GHz），1G内存）

apt-get update
apt-get install ubuntu-desktop
reboot

该方案操作简单，上传速度快。

方案四

在阿里云上申请一个入门级的境外服务器(存储空间够即可),挂载一个支持webdav的网盘(国内如坚果云),在服务器上挂载该网盘,可将文件下载至挂载路径下.（下载命令要加上sudo）（大文件该法有问题，小文件可以尝试）

挂载方法如下:

先安装davfs2:

apt-get update
apt-get install davfs2

创建文件夹,并挂载网盘

mkdir /mnt/webdav
mount -t davfs https://uno.teracloud.jp/dav/ /mnt/webdav

输入完用户名和密码,修改文件夹权限

chmod 777 /mnt/webdav -R

出现如下错误不用在意

chmod: changing permissions of '/mnt/webdav/lost+found': Invalid argument

方案五

去某宝找代下载
