Heroku サーバーにBuild できない

Python初心者です。ローカルで作ったファイルをHerokuのサーバーにdeployしようとしています。
git push heroku master　をすると以下のようにエラーが出ました。
bruch は確認したところ、masterになっていました。
バージョンが違うのかもしれない。と思って、requirements.txtも念のため新しく書き換えましたがだめでした。

どうしたらpushをrejectされるエラーを解決できるのでしょうか。。。

今から回答が付くかはわかりませんが、まずは「requirements.txt」の内容を追記した方が回答が付きやすくなると思います。回答が付きやすくするには、回答者が問題を再現できるような情報を提示するのが大事です。少し長いかもしれませんが、以下のURLにある記事を参考にしてください。 https://www.chiark.greenend.org.uk/~sgtatham/bugs-jp.html
