TypeError: boolean value of NA is ambiguous while running describe_df (df). The cases of pandas.DataFrame and pandas.Series are described below. The advantage here is that it seems like this would allow us to get by without needing to rewrite algos like cut since the machinery used in them would mask-aware. Type RuntimeError: 1excel2excelexcel&~, (tails != -1) and (heads != neg_tails) and (heads != neg_tails) To solve the error, correct the assignment before using the in operators. One of the most commonly reported error in pandas is. def __bool__(self): raise TypeError("boolean value of NA is ambiguous") So basically you can't compare it by calling functions that access the method bool method of a class.

Already on GitHub? 3. 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). Thanks for the reply. As the word "ambiguous" indicates, it is ambiguous what you want to check True or False for, the object itself or each element. However, the || operator actually returns the value of one of the specified operands, so if this operator is used with non-Boolean values, it will return a non-Boolean value. I'll appreciate any good explanation of what was changed and how to solve it, please.
