An AI Twitter bot that only tweets good news, with Python and GPT2

Running AI these days is increasingly simple due to the hard work of open source contributors producing top-notch libraries out there, and research groups opening up their work so others can build on it. One key library doing that is HuggingFace's Transformers library. HuggingFace are a startup building, amongst other NLP-related products, a library and model ecosystem that allows almost anyone to quickly and easily set up AI-powered chat bots that can consume or produce natural language. In this post, I'll demonstrate how I used this library to produce a Twitter bot that is only tweeting made-up (and slightly quirky) good news This blog post isn't meant to explain any theory, but for those who aren't familiar, the easiest way to explain this kind of AI, is they're sophisticated pattern recognition systems. If you feed it enough data, it can build up an ability to recognize the patterns in the english language, to the extent that if you ask it to repeat the pattern, not only will it generate mostly correct English grammar, it might also from time to time generate a coherent sentence!
