Compressing sparse data shouldn't trip up your ML pipeline: here's the fix

Sparse data compression is a smart move for under-sampled training sets, but the error you're hitting comes down to a subtle pandas behavior: the `.sparse` accessor only works on DataFrames where *every* column is already Sparse. Your `sparse_df` may still contain non-sparse columns, or the dtype check isn't matching as expected. Instead of separating and recombining, try compressing the entire DataFrame at once after converting all eligible columns.
