What if the following warning occurs? (numeric_only=True)

I thought it would be good to share all the information that happyarche asked on May 6, 2023!

[Question]

:2: FutureWarning: The default value of numeric_only in DataFrame.corr is deprecated. In a future version, it will default to False. Select only valid columns or specify the value of numeric_only to silence this warning. X_train.corr()

I get a warning when using X_train.corr(). How do I fix this?

[answer]

📌 How to completely resolve the warning : corr( numeric_only=True ) This means that only numeric data will be used. The default is ( numeric_only=False ).

📌 Cause of occurrence : The warning occurs when the version of Pandas installed in Colab is updated. The warning message is the same if it is included in other functions as well as corr(). You can ignore the warning, but it is good to know the solution.

📌 In the test environment?: In the test environment (current standard version), the version is low, so the warning does not occur! However, the libraries and versions that can be used in the test are disclosed just before the practical test.
