I added a tip to be echoed and more detailed help in the comment of the script.
The background is:
After spending hours of downloading data using this script and finding Nonetype errors, I realized the downloading is very unstable and not reliable, so I tried to download the dataset manually. And then I saw the script still trying to download the dataset for me even if I had *.tar.gz files in download folder, so it took me a while to realize that I need to extract them. So I hope adding these tip and comments can help others.
