I'd expect the output for the pd.NA operations above to match the output of the equivalent np.nan operations. Sign in The following raises an error: TypeError: boolean value of NA is ambiguous 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: . loss_function=nn.MSELoss # Also, you take into account it is an experimental feature, hence it shouldn't be used for anything but experimenting: Warning Experimental: the behaviour of pd.NA can still change without warning. setuptools : 41.6.0.post20191030 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). 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. loss = nn.BCEWithLogitsLoss(masks_pred,true_masks) This happens in an if -statement or when using the boolean operations: and, or, and not. One being if the 'TierType' is different than the cell below. For example, if a list is empty (number of elements is 0), it is evaluated as False, otherwise as True. 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). Have a question about this project? If you want to cover whole elements, use axis=None. pandas_datareader: None I'm a little hesitant to coerce integer array to float array due to the likely performance hits but could maybe be fine for a short-term fix. { "type": "module", "source": "doc/api/assert.md", "modules": [ { "textRaw": "Assert", "name": "assert", "introduced_in": "v0.1.21", "stability": 2, "stabilityText .

You.com is an ad-free, private search engine that you control. This article describes the causes of this error and how to fix it. Pandas follows the numpy convention of raising an error when you try to convert something to a bool. 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). For numpy.ndarray of integer int, they perform element-wise bitwise operations. Your membership fee directly supports me and other writers you read. Why does awk -F work for most letters, but not for the letter "t"? Because the validation of the indexer isn't yet updated to handle listlikes that include pd.NA.
