Flask+ReactのアプリをHerokuでデプロイしたいが上手くいかない。condaを使っているのに　ERROR: Invalid requirement: u'blas=1.0=mkl'　と表示

前提・実現したいこと

Python＋Reactで作ったアプリをHerokuでデプロイをしようとしています。
何度やってもapplication errorになってしまいます。
git push heroku mainは上手くいきます。
heroku openをするとapplication errorが表示されます。

発生している問題・エラーメッセージ

heroku logs --tailで表示される内容です。
conda-requirements.txtしか用意していないのですがこれではダメなのでしょうか？
condaのbuildpackは加えているはずです。
