if sorted([_[1] for _ in [l for l in _l3 if l[2] < 1 and l[2] > 0 and l[3] > 10]]) is short than 3
just like [0, 1], cut [1:-1] to _p will be []

_["rule"] = "$X$ > " + str(_p[-1]) 

or

_["rule"] = "$X$ <= " + str(_p[0])

will be

Traceback (most recent call last):

IndexError: list index out of range

try below if it can fix the issue:
p = sorted([[1] for _ in [l for l in _l3 if l[2] < 1 and l[2] > 0 and l[3] > 3]])[:-1]

Thanks

The issue should have been fixed in the version 0.2.1 published on 05/23/2020.
