You will have to install all the libraries imported in the script for it to work. The folders donot have some of the data files that needs to make a demo incase of electrode/probe recording since the memory needed to upload was too high. This will throw an error tellign they couldn't find specific files/folders but if you have an openephys file(in the usual recorded folder structure) you can directly load it as mentioned in the comments of the code. The imaging data has some sample data for playing around.
