在 Google Colab 上安装具有写入权限的 Google Drive

Question

如何在 Google Colab 上安装我的 Google 云端硬盘并具有 write 访问权限？

那是因为当我的 AI 模型尝试更新 Google Drive 上的文件时收到错误：

Traceback (most recent call last):
  File "/content/Deep3DFaceRecon_pytorch/test.py", line 72, in <module>
    opt = TestOptions().parse()  # get test options
          ^^^^^^^^^^^^^^^^^^^^^
  File "/content/Deep3DFaceRecon_pytorch/options/base_options.py", line 167, in parse
    self.print_options(opt)
  File "/content/Deep3DFaceRecon_pytorch/options/base_options.py", line 115, in print_options
    with open(file_name, 'wt') as opt_file:
         ^^^^^^^^^^^^^^^^^^^^^
OSError: [Errno 30] Read-only file system: './checkpoints/facerecon_20230425/test_opt.txt'

顺便说一下，我已经将我的文件夹从 Google Drive 复制到了 Google Colab：

!git clone https://github.com/sicxu/Deep3DFaceRecon_pytorch.git
%cd Deep3DFaceRecon_pytorch

...

!mkdir checkpoints
!cp -r ../drive/MyDrive/Deep3D/facerecon_20230425 checkpoints/

...

更新

在 Google Colab 上，仅尝试在已安装的 Google Drive 中创建文件会引发错误：

!touch ./checkpoints/facerecon_20230425/test_opt.txt

日志：

touch: cannot touch './checkpoints/facerecon_20230425/test_opt.txt': Read-only file system

共享文件夹

我在 Google Colab 上安装的 Google Drive 文件夹（我遇到了权限问题）与我共享。因此，我通过将其内容复制到我自己的新文件夹中，对 shared 文件夹进行了深层复制：

!cp ../drive/MyDrive/Deep3D/facerecon_20230425--original/epoch_20.pth ../drive/MyDrive/Deep3D/facerecon_20230425/
!cp ../drive/MyDrive/Deep3D/facerecon_20230425--original/loss_log.txt ../drive/MyDrive/Deep3D/facerecon_20230425/
!cp ../drive/MyDrive/Deep3D/facerecon_20230425--original/train_opt.txt ../drive/MyDrive/Deep3D/facerecon_20230425/

深度复制后，权限错误已解决。
