Hi! The /path/to/file (or /path/to/wheels as it's shown in the docs) is intended as placeholder for the path to the directory of .whl files you've downloaded. So you'll need to replace that with the actual path to the directory on your system. (Right now, the error is basically trying to tell you that the directory isn't valid because it's not an existing path on your machine.)
Thanks for the reply! I did replace that with my path, actually turns out the error was because I had a windows wheel instead of linux so swapping the wheel file fixed it
