I am trying to deploy a simple jupyter notebook with graphs using heroku and voila. But I am getting the following error. I have spend hours trying to find a solution for this. Please if someone has already solved it let me know. The issues is with buildpacks i guess.
> ! No default language could be detected for this app.
> HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
> See https://devcenter.heroku.com/articles/buildpacks
> ! Push failed
