I've searched the web for information about this, but haven't found a clear answer, that I understand at least.
I have created an Flask app, which utilizes libraries such as Pandas, NumPy, Scikit Learn and some others. This app is eventually meant to be used for commercial use mainly.
Do I have to add their licenses somewhere, when I only import the libraries, and not redistributing their code? If so, where? Since it's not open source and it is a web app, do I need to add it somewhere on my site, is it any best standards to where?
I would like to credit these libraries anyway, but I just want to be sure I'm not doing anything wrong.
Also one of the functions is to deliver back files in e.g. Excel formats, PDF and PowerPoint, do I need to do anything with licenses regarding this? Since two of them are Microsoft owned.
Any help is greatly appreciated!
