How to troubleshoot crashes detected by Google Play Store for Flutter app, Cupertino DateTime picker interfering with scroll behaviour. Now let's assume that we want to filter our pandas DataFrame using a couple of logical conditions. Applying the GroupBy.first aggregation to a object dtype column that contains a pd.NA causes the method to fail with an exception: TypeError: boolean value of NA is ambiguous.Method works fine when using np.nan and also works as expected when the column is first converted to an Int64 dtype column.. Expected Output As it seems by looking at the source code this is intentional as NA isnt really True or False, its boolean value is ambiguous as it is a "missing value indicator". fastparquet : 0.3.2 Now lets assume that we want to filter our pandas DataFrame using a couple of logical conditions. BUG: GroupBy.first fails with pd.NA on Series with object dtype, BUG: Avoid ambiguous condition in GroupBy.first / last. Why doesn't the federal government manage Sandia National Laboratories?

Pandas follows the numpy convention of raising an error when you try to convert something to a bool. For numpy.ndarray of bool, &, |, ~, and ^ operators perform element-wise AND, OR, NOT, and XOR. Note that comparison operations on many objects other than numpy.ndarray return True or False. pyarrow : 0.15.0 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). RuntimeError: bool value of Tensor with more than one value is ambiguous. scipy : 1.3.1 # ValueError: The truth value of a DataFrame is ambiguous. ^ (XOR) is also available. , tree: Error builtins.TypeError: boolean value of NA is ambiguous is raised where there is a missing value in a boolean expression.

Have a question about this project? privacy statement. Now the expression should work as expected and no ValueError will be raised: Alternatively, you can use NumPys logical operator methods that compute the truth values element-wise and thus the truth values wont be ambiguous. 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". Because it is a Python object, None cannot be used in any arbitrary NumPy/Pandas array, but only in arrays with data type 'object' (i.e., arrays of Python objects): In [1]: import numpy as np import pandas as pd. pymysql : None Edit: Looks like I fixed it for now manually finding and converting the columns. blosc : None Understanding how Python Boolean values behave is important to programming well in Python.

In another link of pandas documentation, where it covers working with missing values, is where I believe the reason and the answer you are looking for can be found: NA in a boolean context: xlwt : 1.3.0 It says it will raise an error in the future (the example above is version 1.17.3), so it is better to use size as the message says. 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). Because in principle, pd.cut simply propagates NAs in the input to the output, so they don't need to be passed through the full binning (for which searchsorted is used). pandas follows the NumPy convention of raising an error when you try to convert something to a bool. processor : x86_64 Takeaway: When the source column contains null values or non-boolean values such as floats like 1.0 , applying the Pandas 'bool' dtype may .
