BUG: nlargest raises TypeError "No matching signature found" on Float64Dtype Series, versions >1.3.0 #42816
Description
-
[yes] I have checked that this issue has not already been reported.
-
[yes] I have confirmed this bug exists on the latest version of pandas.
Code Sample, a copy-pastable example
# this works: pandas.Series(numpy.random.random(10)).nlargest(5) # this works on pandas 1.2.5 but fails on 1.3.0 and 1.3.1. All Float64DType Series seem to have the same issue pandas.Series(numpy.random.random(10)).astype('Float64').nlargest(5)Software/hardware
python version: 3.8.10
Ubuntu 20.04
(Intel Tiger Lake CPU)
