使用shell脚本下载Nuscenes数据集

数据集官方地址https://www.nuscenes.org/download

一、 创建shell脚本

首先创建一个新目录，用来存放.sh文件

mkdir scripts

 在这目录中使用cat命令进行创建和编辑dataset.sh文件,可以根据自己需求来进行命名

cd scripts
cat > dataset.sh

 二、 编辑shell文件

cat命令输入之后会直接进入到文件编辑，再编辑中输入如下代码

wget -c -O 数据集名字 "下载网址"

 如需下载

 直接点击Asia，会跳转到下载界面

 第一行就是数据集的名字，第二行就是下载的地址（nucenes下载网址不定时更新，需要自己粘贴下载地址），将相应的名称和网址进行复制粘贴，得到如下

wget -c -O nuimages-v1.0-all-sweeps-cam-front-left.tgz "https://s3.ap-southeast-1.amazonaws.com/asia.data.nuscenes.org/public/nuimages-v1.0/nuimages-v1.0-all-sweeps-cam-front-left.tgz?AWSAccessKeyId=ASIA6RIK4RRMEAXBKTWZ&Signature=k9keIo8aPJL8ppzb9WhzXSb4utA%3D&x-amz-security-token=IQoJb3JpZ2luX2VjEK3%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaCXVzLWVhc3QtMSJHMEUCIFkIqjG9OEzsO0zwBboP629drkJSxg77UZSenRmTYObTAiEAnBvD9IWMcxVu%2BlCc2vqx2gAhrR7UKo2vzf6BqTTlTF0q%2FQIIpv%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FARADGgw5OTkxMzk2MDk2ODgiDBYqwRd9zCn58HFRBirRApAtGJh9A5AkS8Zs6BwBsv79VOpDrdNdEPY8xOger%2FNYBgBrXV50Y63fOOow5wphQjyFhO26a3tbpDixK6eVZt0%2FJ6%2FHImBXAezOb%2F1P%2FyefZ5XqqXFxbxxbCjQtxhSMTdgkCx7XS2UVH2QsvH9FgN%2BNdlDSjSlYCCxnEsZcFhZS3M%2F87HFiDkDF962OJVYGEk4AdcZZws4GKQFsHoT478GqySQXQsnhcI7RW9fMQLPa5g%2Fo%2FUMR%2BVI8rrK6%2F1HCh5awG96fl9fcAZ%2BRCHT0Wn3aGeJk9JmTkG85aKt1HcE8DsQD5Su%2F1tHuKwv2nMgS5bXrtadmJRhgjmQYS8%2BC4MJUalc614g6jF4FRQO02Opfuzx6g9DvBXCdzwK%2BRI8Pnlj65lqKg4k5v%2FJFlfbwpp5LqFtX4RrnMIaKkf9E2%2BR1m71%2BMdO%2FwZAB2nFngBPz538wg4CKogY6ngHpCLpetp1xYy7%2BiYx3IFWIFtMgS4A6wCel1Hsy3FH%2BWUpExY3r%2B4c4ExDr0vQ35HmDHlBEJXZK88xXeU3bMr4GhuiI%2BbIKVkMyLP47j65Oj9XL78BtxYIh6KIUc3tn%2BTSef2OhqCf3jKGuXQJQ%2FRMf%2FgiU07ftLsQ4Hs%2BnB5W7Ki40XAwY%2BSuvWzsgYPct%2BwQX1U4syoIgjFqM7GyWuw%3D%3D&Expires=1682513125"

如需同时下载多个数据集则需要在每个网址之后加一个&，最后一个网址之后也需要添加

cttl+d两次保存并退出文件

三、  执行sh文件

使用chmod命令将文件成为可执行的状态

chmod u+x dataset.sh

最后使用bash命令来运行这个脚本

bash dataset.sh

出现如下提示

 成功

ps.使用shell脚本下载数据集速度比较快，而且如果出现连接中断的问题系统会自动重新连接，从断掉的地方继续下载
