Uplift By Percentile

[prachi-01998]

I am facing an issue when using the uplift_by_percentile metric. Can someone explain how this is actually calculated and what should be the dimensions of the different inputs? I am attaching a snapshot of the error.

I tried using the versions suggested in the issue that you have mentioned but it does not solve the error. Instead it gives me errors when I am trying to run the tutorials.
If I use the scikit-uplift version 0.3.2. The tutorials does not work.

I'm getting this error too with uplift_by_percentile() and plot_uplift_by_percentile()

plot_qini_curve() does work though.

I found a temporary fix, kind of ugly but it works.. I describe the fix in the notebook below. The problem stems from trying to convert a list that looks like this

['total', array(float), array(float), , array(float), array(float), array(float)]

into a 1d numpy array
