Python Pandas – How To Supress Performancewarning?

How I can supress a PerformanceWarning in pandas? I've already tried warnings.simplefilter(action='ignore', category=PerformanceWarning), but it gives me a NameError: name 'Perform

Solution 1:

PerformanceWarning is not a built-in warning class so you can't call it directly in category argument. You can try the following code:

import pandas as pd
import warnings

warnings.simplefilter(action='ignore', category=pd.errors.PerformanceWarning)

I have no idea how to reproduce the PerformanceWarning but i tested a similar approach to the "SettingWithCopyWarning" pandas warning and it worked. Let me know if it works.
