Note that different versions may behave differently. 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. gcsfs : None A boolean array (any NA values will be treated as False). To learn more, see our tips on writing great answers. Any advices about error reproduction are appreciated. It would be indeed be nice to at least solve things like pd.cut for 1.0, as this was working for Int64 dtype before. tables : 3.5.1 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). What does ValueError: The truth value of a Series is ambiguous. For numpy.ndarray of bool, &, |, ~, and ^ operators perform element-wise AND, OR, NOT, and XOR.

I was planning to optimize some low-level functions to speed things up and make PP more stable. In Python, objects and expressions are evaluated as bool values (True, False) in conditional expressions and and, or, not operations. On master trying to use pd.NA as an input to searchsorted fails, and trying to use the searchsorted of an array containing pd.NA also fails: Note that the np.nan equivalent works fine: This has downstream effects on anything that relies on searchsorted, e.g. . Not the answer you're looking for? privacy statement. Each task has a predicted execution time and each processor has a specified time when its core becomes available. Of course, parentheses are also acceptable. The searchsorted call here is to numpy but we have our own internal algos.searchsorted that we could make mask-aware, and then just ensure that all of our internal searchsorted calls go through algos.searchsorted and not directly to numpy. Since the actual value of an NA is unknown, it is ambiguous to convert NA to a boolean value. Should I follow what @jorisvandenbossche said and update integer array to float array in searchsorted related methods? odfpy : None Return: 0 1, The open-source game engine youve been waiting for: Godot (Ep.

As it seems by looking at the source code this is intentional as NA isn't really True or False, its boolean value is ambiguous as it is a "missing value indicator". Currently, indexing with a list including pd.NA (so the list version of indexing with a BooleanArray or IntegerArray) works on the array, but not on Series: ("works" = raising the correct error message). TypeError: boolean value of NA is ambiguous Because the validation of the indexer isn't yet updated to handle listlikes that include pd.NA.
