Issue plotting P_alive

I’m running the following code in a local Jupyter Notebook. https://github.com/susanli2016/Machine-Learning-with-Python/blob/master/CLV_Online_Retail.ipynb I had an issue with Matplotlib after installing Lifetimes and had to reinstall via Conda.

The code all runs as expected, predict works etc and all the plots run correctly except for plot_history_alive which only plots the purchases, but not P_alive.

I get no errors or warnings.

I can run predict on different period lengths for different customers and it runs fine, so might be related to the libraries? I had a quick look at the plot_history_alive function but I couldn’t see any reason why it shouldn’t work.

I’m using:

matplotlib==2.2.2
pandas==0.23.4
lifetimes==0.9.1.0

Any ideas on where I should look first to debug?

Thanks A

I was able to get the CDNOW data to work see: https://colab.research.google.com/drive/1oc8vbnG-kHc_xaSZStNBH3e1R_VFboqb

But I wasn’t able to get https://github.com/susanli2016/Machine-Learning-with-Python/blob/master/CLV_Online_Retail.ipynb to work. Please see: https://colab.research.google.com/drive/15Ab4lbeai0TnVcaWOKF2ObpEtQVNnhuQ

In the original github, it looked like this:

The changes I made to the notebook were as follows: I downgraded scipy from 1.2.0 to 1.1.0 because of: https://github.com/CamDavidsonPilon/lifetimes/issues/274

I commented out from lifetimes.estimation import * because it doesn’t seem to exist anymore

Thanks! Teresa
