第一个错误是:

当你有1D时需要2D

意外缩进

我的代码是:

from sklearn import metrics
    from sklearn.linear_model import LogisticRegression

    model=LogisticRegression(solver="liblinear")

    #x_train=x_train.values.reshape(-1,1)
    #y_train=y_train.values.reshape(-1,1)
    model.fit(x_train,y_train)

    y_predict=model.predict(y_test)
    y_predict = y_predict.values.reshape(-1,1)
     y_predict = column_or_1d(y, warn=True)
    coef_df=pd.DataFrame(model_coef_)
    coef_df['intercept']=model_intercept_

    print(coef_df)
