Bonjour @ageron, your book is helping a lot, I hope this helps you: Changed on line 1208 housing.corr() to housing.corr(numeric_only=True) to remove deprecated warning for future versions.

Starting as of Pandas v2.0.0+, the default param value of numeric_only=False.

I was encountering a ValueError when creating a correlation matrix in the Chapter 2 code: corr_matrix = housing.corr() about converting a string to a float and it was fixed by manually defining numeric_only=True.
