First of all, thank you for being part of this beautiful community.

Explaining my problem. When I implemented my application in heroku, the following error appears when trying to install the somoclu library. locally I have no operational problems with any of the libraries.

I have tried to solve this problem by downloading the previous versions of the used libraries and the problem is still present.

I attach the libraries I am using and a screenshot of the error in heroku

matplotlib == 3.2.2

numpy == 1.18.5

pandas == 1.0.5

plotly == 4.8.2

streamlit == 0.62.1

somoclu == 1.7.5

scikit-learn == 0.23.1
