For anyone using Rasa who wants lookup tables with most major cities and countries in the world! Normal .csv files with one column are also provided!
The cities are obtained from GeoLite2 and have been looked through and organized by myself to remove repetitive entries, entries with strange non utf-8 characters, and entries which are far too long (Over ~80 characters)
To use the cities.yml and countries.yml, just pop them into your NLU data folder, and add a version section if you don't want the "version" warning.
If you want the clean files without additional YML formatting, check out the .csv versions of the files!
