It's a bit hard to see what exactly is happening without more code but from what I see in your error messages, you define X, Y but where are X_train, X_test, y_train, and y_test instantiated? from scipy.stats import chi2įrom pose import ColumnTransformerįrom sklearn.feature_selection import SelectPercentileįrom trics import r2_score, mean_absolute_errorįrom sklearn.preprocessing import OneHotEncoder, StandardScalerįrom sklearn.linear_model import LinearRegressionįrom sklearn.model_selection import train_test_split I think I need t your texto do type conversion when I do research on the internet, but frankly, I don't know where to do it.
