Error UsageError on author argument

[Hackathorn]

When executing watermark on RASBT-STAT453 notebook with...
%watermark -a 'Sebastian Raschka' -v -p torch

Get error message...
UsageError: unrecognized arguments: Raschka
and no other watermark info.

Simple work-around is to insert underscore between first/last names.

Using VS Code 1.60.2 notebook with Python 3.8 & Torch 7.26 under Win10. Installed watermark-2.2.0 with conda from conda-forge.

Thanks for the note, Richard. I think the problem is the single quotation marks. If you change it to double quotation marks, e.g.,

%watermark -a "Sebastian Raschka" -v -p torch

I believe it should work. I should be more careful with that in the future and update the documentation to warn about that.
