@ritchie46 - just tested it out in the latest release, works perfectly, thank you! Really appreciate all of the work you guys do, certainly continuing on my quest to use...

@yusufuyanik1 would it make sense to give a big red warning in the streamlit app when these optional dependencies aren't installed, telling the user to install as `pip install pdstools[app]`?

@yusufuyanik1, maybe we should add the dependency warning to the streamlit app as part of https://github.com/pegasystems/pega-datascientist-tools/pull/250? I don't think this is a real issue, but helping the user point out...

I don't think there is enough demand for this and it's very easy for these kind of evaluation metrics to be misleading in our setup where we have probability models...

Not needed as functionality in pdstools, closing.

@yusufuyanik1 conceptually i'm sort-of fine with that but we need to give a clear explanation/instruction on where exactly to put the data whenever we hit this. What i may prefer...

@yusufuyanik1 - is this PR still relevant / active?

We want to add this to the pdstools app still, but the class & article are there, so closing it.

The article should be fully in sync with whatever's there in the repo, it's not tied to any versions. Let's check tomorrow.
