无法在 Colab 笔记本中挂载 Google Drive 文件夹

Question

我正在尝试安装一个目录以https://drive.google.com/drive/folders/my_folder_name在 google colab 笔记本中使用。

安装文件夹的说明显示了以 /content/drive 开头的目录示例：

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

但我的目录不以 开头/content/drive，并且我尝试过的以下操作均导致ValueError: Mountpoint must be in a directory that exists：

drive.mount("/content/drive/folders/my_folder_name")
drive.mount("content/drive/folders/my_folder_name")
drive.mount("drive/folders/my_folder_name")
drive.mount("https://drive.google.com/drive/folders/my_folder_name")

如何安装不以 开头的 google 驱动器位置/content/drive？

Answer 1

中的路径drive.mount('/content/drive')是在笔记本运行的虚拟框中安装 GDrive 的路径（安装点）（请参阅 Unix/Linux 中的“安装点”）。它并不指向您尝试访问 Google 云端硬盘的路径。保持"/content/drive"原样并像这样工作：

from google.colab import drive
drive.mount("/content/drive") # Don't change this.

my_path = "/path/in/google_drive/from/root" # Your path
gdrive_path = "/content/drive" + "/My Drive" + my_path # Change according to your locale, if neeeded.
# "/content/drive/My Drive/path/in/google_drive/from/root"

并修改my_path为位于 GDrive 中的所需文件夹（我不知道是否会"/My Drive/"根据您的区域设置进行更改）。现在，Colab Notebooks 默认保存笔记本，就"/Colab Notebooks"我而言，我的 GDrive 的根实际上是gdrive_path = "/content/drive/My Drive"（我猜你的也是）。这给我们留下了：

import pandas as pd

from google.colab import drive
drive.mount("/content/drive") # Don't change this.

my_path = "/folders/my_folder_name" # THIS is your GDrive path
gdrive_path = "/content/drive" + "/My Drive" + my_path
# /content/drive/My Drive/folders/my_folder_name

sample_input_file = gdrive_path + "input.csv" # The specific file you are trying to access
rawdata = pd.read_csv(sample_input_file)
# /content/drive/My Drive/folders/my_folder_name/input.csv

成功挂载后，在授予drive.mount API 权限后，系统会要求您粘贴验证代码。

更新：GColab 不再需要复制/粘贴代码，而是通过通常的 Google 登录页面简单地确认您的身份。
