This cannot be solved: we don't have access to sololearn server to install module ^^

Anyway, you could contact sololearn to ask if they can install a particular module, but remember that any module related to graphic output will not work in sololearn code playground context, as output is necessarly text only, due to the way execution of code is handled ;)

To contact sololearn, use feedback feature of the app, or one of the way listed on this page:
