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 'PerformanceWarning' is not defined

Solution

  • 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.
