Colab tutorials depend on local Google Drive data paths

[ShengxuanQUAN]

When testing the tutorials in Colab, I noticed that some notebooks rely on local Google Drive paths, for example:

dir_path = '/content/drive/MyDrive/02740_data/003-basic-operations/'
os.chdir(dir_path)

In basic_operations.ipynb

And Error examples:

FileNotFoundError: No such file or directory: '/content/drive/MyDrive/02740_data/003-basic-operations/'
FileNotFoundError: No such file: '/content/edu/body-003.dcm'

It may be better to make these data dependencies explicit and reproducible, e.g. by adding a data download/setup cell, including small demo files in the repo, or documenting where users should get the required files.

I just reran basic_operation.ipynb and the problem is still exists. So the notebook successfully mounts Google Drive, but then it looks for a folder under

/content/drive/MyDrive/02740_data/003-basic-operations/

Since this folder does not exist in my personal Google Drive, the notebook cannot continue after mounting. My understanding is that the current setup may still depend on the contributor's personal dataset path, which might not be directly accessible to new/external users?

If this is due to a mistake in my setup or operation, please feel free to point it out directly :)
