Use a.empty, a.bool(), a.item(), a.any() or a.all(). This would require some care to do in a way that minimizes any performance hits though. Should I follow what @jorisvandenbossche said and update integer array to float array in searchsorted related methods? 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". Already on GitHub? pytest : 5.2.0 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. ValueError: The truth value of an array with more than one element is ambiguous. pandas_datareader: None Niv Cohen Niv Cohen. # """Entry point for launching an IPython kernel.

To put this into a more simple context, consider the expression below, that once again will raise this particular error: When multiple conditions are specified and chained together using logical operators, each individual operand is implicitly turned into a bool object, resulting into the error in question. lxml.etree : 4.4.1 TypeError: boolean value of NA is ambiguous Should I follow what @jorisvandenbossche said and update integer array to float array in searchsorted related methods? 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). Well occasionally send you account related emails. Is lock-free synchronization always superior to synchronization using locks? not returns element-wise NOT. Furthermore, it provides a valuable piece of advise: "This also means that pd.NA cannot be used in a context where it is evaluated to a boolean, such as if condition: where condition can potentially be pd.NA. Already on GitHub? hypothesis : 4.36.2 df['date_Week'] = df['date_Week'].astype(float) This seems like some leaky abstraction between Fast.ai and Pandas doing the week conversi Well occasionally send you account related emails. python; python-3.x; pandas; Share. def __bool__(self): raise TypeError("boolean value of NA is ambiguous") bool.
