Say we want to keep only the rows whose values in column colB are greater than 200 and values in column colD are less or equal to 50. df = df[(df['colB'] > 200) and (df['colD'] <= 50)] The above expression will fail with the following error: pandas_gbq : None The program throws the . This happens in a if or when using the boolean operations, and, or, or not. According to your error trace back, It's definitely pd.NA(pandas._libs.missing.NA) that causes the bug. and and or return either left or right side objects instead of True or False. Evaluating numpy.ndarray as a bool value raises an error. Theoretically Correct vs Practical Notation. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The above expression will fail with the following error: The error is raised because you chain multiple conditions using logical operators (such as and, or, not) resulting in ambiguous logic since the returned results are column-based for each individual condition specified. gcsfs : None Sign up for a free GitHub account to open an issue and contact its maintainers and the community. BUG: GroupBy.first fails with pd.NA on Series with object dtype, BUG: Avoid ambiguous condition in GroupBy.first / last. Note that &, |, and ~ are used for bitwise operations on integer values in Python. As mentioned above, to calculate AND or OR for each element of these numpy.ndarray, use & or | instead of and or or. 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". NA to a boolean value. returns: TypeError: boolean value of NA is ambiguous. For numpy.ndarray of integer int, they perform element-wise bitwise operations. byteorder : little Already on GitHub? Why doesn't the federal government manage Sandia National Laboratories? When it is, it returns a Boolean value. Let's start off with .str: imagine that you have some raw city/state/ZIP data as a single field within a pandas Series.. pandas string methods are vectorized, meaning that they . In most cases, note the following two points. Here is an example of how the error occurs. F While NaN is the default missing value marker for reasons of computational speed and convenience, we need to be able to easily detect this value with data of different types: floating point, integer, boolean, and general object. I'm going to move this off 1.0.0, I think that .searchsorted(NA) not working will be a known limitation. To learn more, see our tips on writing great answers. By clicking Sign up for GitHub, you agree to our terms of service and Boolean Value bool(None) False bool(float('nan')) True bool(np.nan) True bool(pd.NA) Traceback (most recent call last): TypeError: boolean value of NA is ambiguous 3.7.3. Every time you run an expression with operands and operators, the Python tries to evaluate individual values to boolean. 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). 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. Yes, that definition above is a mouthful, so let's take a look at a few examples before discussing the internals..cat is for categorical data, .str is for string (object) data, and .dt is for datetime-like data. The pd.read_html() has gained support for the na_values, converters, keep_default_na options . all() returns True if all elements are True, any() returns True if at least one element is True. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? matplotlib : 3.1.1 Usually it is the wrong use of Loss, for example, the predicted value is entered into "Class" by mistake. So basically you cant compare it by calling functions that access the method bool method of a class. Since and and or have lower precedence than comparison operators (such as <), there is no error without parentheses in this case. Version information is essential in reproducing and resolving bugs. # """Entry point for launching an IPython kernel. 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. The first sentinel value used by Pandas is None, a Python singleton object that is often used for missing data in Python code. Remember that the English words and and or are often used in the form if A and B:, and the symbols & and | are used in other mathematical operations. A boolean array (any NA values will be treated as False). In this function, numpy.count_nonzero() is called with a pandas.Series as input, which is slow and risky especially when series contains Na.
