BUG: wrong errors when indexing with list that includes pd.NA, TST: expand tests for ExtensionArray setitem with nullable arrays. pandas_gbq : None 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. to your account. In Pandas missing value is represented by pd.NA. However, once your iterable is a pandas array, Nones have been converted into pd.NAs, and therefore will not be removed. Sweetviz is an open-source Python library that generates beautiful, high-density visualizations to kickstart EDA (Exploratory Data Analysis) with just two lines of code. 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). dateutil : 2.8.0 Failing food explorer: boolean value of NA is ambiguous. This happens in an if -statement or when using the boolean operations: and, or, and not. On master trying to use pd.NA as an input to searchsorted fails, and trying to use the searchsorted of an array containing pd.NA also fails: Note that the np.nan equivalent works fine: This has downstream effects on anything that relies on searchsorted, e.g. pandas.DataFrame import numpy as np import pandas as pd cols = ['var1', 'var2', 'var3. Notice that Pandas missing value is not exactly the same as empty Numpy Nan value, as we could check as follows in the Shell: Replace the empty values by what suits best to you by using Pandas fillna() method to solve the issue. @jschendel Is this issue still occurring?
