As mentioned in the response below, we have posted the challenge with a respective data set of ~ 500k tweets from 100 regions around the world - https://github.com/1712n/yachay-public/tree/master/conf_geot...

We are working on adding more data as well - feel free to create a GitHub issue if there's more you need - we're going to be working on everything there is to do to help the developers here:)
