One of the most commonly reported error in pandas is. # ValueError: The truth value of an array with more than one element is ambiguous. Have a question about this project? Takeaway: When the source column contains null values or non-boolean values such as floats like 1.0 , applying the Pandas 'bool' dtype may . Have you find out what causes the riskiness while calling numpy.count_nonzero() with a pandas.Series? In our example, numpy.logical_and method should do the trick: In todays guide we discussed about one of the most commonly reported errors in pandas and Python, namely ValueError: The truth value of a Series is ambiguous. fastparquet : 0.3.2 Well occasionally send you account related emails. Any idea why I would get the error message 'TypeError: boolean values of NA is ambiguous' (also shown in image). 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). Here is an example of how the error occurs. Sign in privacy statement. I get the following: returns: TypeError: boolean value of NA is ambiguous. TypeError: boolean value of NA is ambiguous Because the validation of the indexer isn't yet updated to handle listlikes that include pd.NA.
