Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Longer term: I don't think it is easy to fix the searchsorted directly, as here it is a numpy call, where the passed integer array gets converted to an object numpy array (at least if we don't want to change the coercing behaviour of IntegerArray and the comparison and boolean behaviour of pd.NA). Also in my example, there are no missing values in the series. For numpy.ndarray of bool, &, |, ~, and ^ operators perform element-wise AND, OR, NOT, and XOR. #,Tracker,Status,Priority,Subject,Assignee,Updated 556,Bug report,Closed,Low,Field should be Layer in GRASS lingo,Aaron Racicot -,2009-08-22 12:52 AM 722,Bug report . lxml.etree : 4.4.1 Using numpy.ndarray of bool in conditional expressions or and, or, not operations raises an error.
