I'm learning #mlflow for real for the first time and boy, I wish I was recording my reactions. Nothing makes sense!

Why am I getting this WARNING? Why are there little green and gray circles without tooltips? Why was this apparently successful run marked as "Failed"?

This is not a critique just on MLFlow. Software in general is often inscrutable and makes you feel stupid. After a while we get used to it and then write tutorials like "foo is easy, you just simply..."
