copyfile() missed an argument

[w4-jonghoon]

While exporting features, I got the following error:

$ python main.py --export_to_features
[~] The used device is: cpu
[~] The gpu ids are: [0]
[-] The configuration file specified use_cuda=True but cuda isn't available
Downloading http://homepages.inf.ed.ac.uk/jyamagis/release/VCTK-Corpus.tar.gz
Using existing raw folder
Traceback (most recent call last):

    vctk = VCTK(configuration['data_root'], ratio=configuration['train_val_split'])

    os.path.join(dset_abs_path, "COPYING"),
TypeError: copyfile() missing 1 required positional argument: 'dst'

The error is based on this:
(src/dataset/vctk.py:138)

        shutil.copyfile(
            os.path.join(dset_abs_path, "COPYING"),
        )

I think that copying is unnecessary.
Could you check this error please?
