Understanding Pandas Rolling Returns NaN When Infinity Values Are Involved.
Understanding Pandas Rolling Returns NaN When Infinity Values Are Involved Problem Description When using the rolling function on a pandas Series that contains infinity values, the result contains NaN even if the operation is well-defined, such as minimum or maximum. This issue can be observed with the following code: import numpy as np import pandas as pd s = pd.Series([1, 2, 3, np.inf, 5, 6]) print(s.rolling(window=3).min()) This code will produce an output where NaN values are introduced in addition to the expected result for minimum operation.
