1. run sklift.metrics.uplift_by_percentile,sklift.metrics.plot_uplift_by_percentile,raise error: ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (6,) + inhomogeneous part.
2. git code url : https://github.com/maks-sh/scikit-uplift/blob/master/notebooks/uplift_metrics_tutorial.ipynb

Expected behavior

Environment

• scikit-uplift version (0.5.1):
• pandas version (2.2.2):
• numpy version (1.26.4):

Additional context

[gaohai2017]

the error caused by numpy version, and the same time, you should install the appropriate version of pandas & sklift accordingly.
the follow version works:
pandas 2.0.3
scikit-uplift 0.3.2
numpy 1.21.6
