google-colaboratory - 如何在 Colab 中以 root 身份挂载 "drive/MyDrive"？

Question

我在 Colab 中安装我的 Google Drive，如下所示:

from google.colab import drive
drive.mount('/content/drive')

现在，当我想解压缩位于“drive/MyDrive/”文件夹中的文件“tommuddi.zip”时

我必须使用“drive/MyDrive/tommuddi.zip”访问它，这很麻烦:

from zipfile import ZipFile
file_name = 'drive/MyDrive/tommuddi.zip'

with ZipFile(file_name, 'r') as zip:
  zip.extractall()
  print('Done')

相反，我想访问正在使用

file_name = 'tommuddi.zip'

我怎样才能让Colab假设“MyDrive”是根目录以便上面的工作正常？

当我尝试这个时...

from google.colab import drive
drive.mount('/content/drive/MyDrive')

...它抛出错误

谢谢!

明白了:必须使用 CD 驱动器才能进入该目录:

from google.colab import drive
drive.mount('/content/drive')
%cd drive/MyDrive

这样做之后，我们就进入了MyDrive目录，我们可以直接访问它的文件。
