Movielens-25M dataset missing "ratings.csv" file

[mengzaiqiao]

Describe the bug

I tried to use the Movielens-25M dataset, but it doesn't work. It complains on missing "ratings.csv" file. The file is missing indeed and it's called ratings.dat in the archive.

To Reproduce

Please provide a Minimal, Complete, and Verifiable example here. We hope we can simply copy/paste/run it. It is also nice to share a hosted runnable script (e.g. Google Colab), especially for hardware-related problems.

Describe your attempts

• [ ] I checked the documentation and found no answer
• [ ] I checked to make sure that this is not a duplicate issue

You should also provide code snippets you tried as a workaround, StackOverflow solution that you have walked through, or your best guess of the cause that you can't locate (e.g. cosmic radiation).

Context

• OS [e.g. Windows 10, macOS 10.14]:
• Hardware [e.g. CPU only, GTX 1080 Ti]:
• Environment [e.g. Pytorch 1.4, Tensorflow 2.0]:

In addition, figure out your used Beta-Recsys version. Then attach the corresponding label on the issue.

Additional Information

Other things you want the developers to know.

@mengzaiqiao I try to download MovieLens-25M both using the url in the code and from the website directly. These is NO ratings.dat files in the folder.
