Customize search results with 150 apps alongside web results. ValueError: The truth value of an array with more than one element is ambiguous. For numpy.ndarray of integer int, they perform element-wise bitwise operations. 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. In the following sample code, NumPy is version 1.17.3, and pandas is version 0.25.1. Have you find out what causes the riskiness while calling numpy.count_nonzero() with a pandas.Series?

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. Getting key with maximum value in dictionary? Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? It's used to represent the truth value of an expression. Evaluating numpy.ndarray as a bool value raises an error.

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. Bitwise operations with scalar values are also possible. If you want to cover whole elements, use axis=None. For example, if the element is an integer int, it is False if it is 0 and True otherwise. dropna , pandaspandasnumpynp.isnan(a)np.isnat(a)if a is np.nan, np.float642021dataframe2007.0int, 2mergeintfloatfloat64nan, 3pandas1.0mergedataframedataframepd.NA dataframe.convert_dtypes()dataframe.fillna(pd.NA, inplace=True)pd.NAmergefloat64dataframe.fillna(np.nan, inplace=True)bug Merging two dataframes with pd.NA in merge column yields TypeError: boolean value of NA is ambiguous, pandas1.0, qq_45017838: ValueError: The truth value of a Series is ambiguous. { "type": "module", "source": "doc/api/assert.md", "modules": [ { "textRaw": "Assert", "name": "assert", "introduced_in": "v0.1.21", "stability": 2, "stabilityText .
