Google Colab 驱动器安装（带下划线）无法正常工作

Question

直到昨天（1月20日）我还可以连接到另一个谷歌驱动器帐户（使用drive._mount），但是当我今天尝试这个时，谷歌colab向我显示了这个错误：

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

    /usr/local/lib/python3.7/dist-packages/google/colab/drive.py in _mount(mountpoint, force_remount, timeout_ms, use_metadata_server, ephemeral)
    294       wrote_to_fifo = True
    295     elif case == 5 and not use_metadata_server:
--> 296       raise ValueError('mount failed: invalid oauth code')
    297     elif case == 6:
    298       # Terminate the DriveFS binary before killing bash.

ValueError: mount failed: invalid oauth code

奇怪的是，错误告诉我“无效的oauth代码”，但不让我连接到谷歌页面并复制代码！

我设置了 use_metadata_server=True 但这一次，出现了新的错误：

    from google.colab import drive
    drive._mount('/content/drive/', use_metadata_server=True)
ValueError                                Traceback (most recent call last)
<ipython-input-5-42a561ce7057> in <module>()
      1 from google.colab import drive
----> 2 drive._mount('/content/drive/', use_metadata_server=True)

/usr/local/lib/python3.7/dist-packages/google/colab/drive.py in _mount(mountpoint, force_remount, timeout_ms, use_metadata_server, ephemeral)
    285             ': timeout during initial read of root folder; for more info: '
    286             'https://research.google.com/colaboratory/faq.html#drive-timeout')
--> 287       raise ValueError('mount failed' + extra_reason)
    288     elif case == 2:
    289       # Not already authorized, so do the authorization dance.

ValueError: mount failed

我还使用了drive.mount，但显示弹出窗口并要求我输入另一个帐户凭据。当我输入时，出现这个错误：

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

MessageError                              Traceback (most recent call last)

      1 from google.colab import drive
----> 2 drive.mount('/content/drive/')

    104         reply.get('colab_msg_id') == message_id):
    105       if 'error' in reply:
--> 106         raise MessageError(reply['error'])
    107       return reply.get('data', None)
    108 

MessageError: Error: credential propagation was unsuccessful

我认为这是新政策。有解决办法吗？

此功能已被删除，您现在只能从笔记本电脑的同一帐户安装谷歌驱动器。 https://github.com/googlecolab/colabtools/issues/2562#issuecomment-1017869732

Answer 2

目前唯一有效的解决方案是两个月前的类似问题：

!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null
!apt-get -y install -qq google-drive-ocamlfuse fuse
from google.colab import auth
auth.authenticate_user()
from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()
import getpass
!google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass()
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}
%cd /content
!mkdir drive
%cd drive
!mkdir MyDrive
%cd ..
%cd ..
!google-drive-ocamlfuse /content/drive/MyDrive

希望正常的方式drive.mount能尽快修复！
