The above behavior is due to Python using equality as a fallback when hash collisions occur and our defined behavior of bool (pd.NA) raising. This article describes the causes of this error and how to fix it. I'm a little hesitant to coerce integer array to float array due to the likely performance hits but could maybe be fine for a short-term fix. Use a.any () or a.all () Let's take the advice from the exception and use the .any () or .all () operators. Note that comparison operations on many objects other than numpy.ndarray return True or False. This is because & and | have higher precedence than comparison operators (such as <).

This happens in a if or when using the boolean operations, and, or, or not. 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). Output is a fully self-contained HTML application. Error builtins.TypeError: boolean value of NA is ambiguous is raised where there is a missing value in a boolean expression. Sign in pandas.DataFrame import numpy as np import pandas as pd cols = ['var1', 'var2', 'var3. However, since I can't test on your data, I don't know why it's in your data frame.
