Hello. I'm trying to solve an issue regarding Python 2.7 and latest version of Tornado. I know that the support for 2.7 ended few days back in Tornado's latest version. However, I'm trying to figure out what is actually installing Tornado during our deployments. Is Tornado as a dependency in for example IPython? The setup I'm currently working on is not very robust and I have not dealt with Jupyter Notebook before..
