OSError in speechbrain.pretrained.fetching

[BrownsugarZeer]

SpeechBrain really give me a big help, thanks.

OS: Win 10
Python version: 3.8.6

def fetch(
    filename,
    source,
    savedir="./pretrained_model_checkpoints",
    overwrite=False,
    save_filename=None,
    use_auth_token=False,
):
...
elif pathlib.Path(source).is_dir():
        # Interpret source as local directory path
        # Just symlink
        sourcepath = pathlib.Path(sourcefile).absolute()
        MSG = f"Fetch {filename}: Linking to local file in {str(sourcepath)}."
        logger.info(MSG)
        _missing_ok_unlink(destination)
        destination.symlink_to(sourcepath)
...

The following error occurred if the source is a valid directory path
OSError: [WinError 1314] A required privilege is not held by the client

The code destination.symlink_to(sourcepath) is a little inconvenient for Windows users, as requires to run with admin privileges because of some security considerations. I wonder if it is possible to switch to copying or any alternatives instead of symlinking in a future release.

Good point. I am not sure that it would be possible to find a solution that will suit all the existing OS. SpeechBrain has been designed for linux-based OS. @Gastron any idea?

This is unfortunate. Still, personally I feel that since this can actually work on Windows, the permissions just need to be set right, we should probably keep it as it is for now. On a larger scale, this fetching functionality is in danger of becoming a mess, it tries to support so many different sources etc. We could reconsider this issue if we end up refactoring the whole functionality.

Closing, I guess what I said above is the current plan for this.
