其他任何一个都不起作用，因此欢迎任何想法.

解决方案

此后，我尝试了许多解决方案，但是最好的解决方案是使用"rsync" Linux命令将文件从驱动器获取到collab的存储中(安装rsync使用！apt install rsync")，然后使用解压缩"命令.此后速度很快(71.32MB/s).

I have a dataset in google drive which I want to use in google colab.But I can't unrar the rar files by any means.So far I have tried installing python libraries and also ubuntu packages like "unrar ,rar ,unrar-free ,unar ,unp" and I just can't open the damn file.Here are the results of each command:

!rar x data.rar

None of the others a re working either so any ideas are welcomed.

解决方案

I have tried lots of solutions since then, but the best one has been to get the file from drive to collab's storage using "rsync" Linux command (install rsync using "!apt install rsync") and then "unzip" command. It is lightning fast after that (71.32MB/s).
