我正在尝试使用H2OGeneralizedLinearEstimator函数预测Kaggle comp中的测试时间。该模型通常在第3行训练，指标都是合理的。然而，当我进入预测步骤时，尽管测试数据帧与列车数据帧匹配，但仍会出现错误。
之前有没有人见过这个错误？
h2o_glm = H2OGeneralizedLinearEstimator()
h2o_glm.train(training_frame=train_h2o,y='y')
h2o_glm_predictions = h2o_glm.predict(test_data=test_h2o).as_data_frame()
test_pred = pd.read_csv('test.csv')[['ID']]
test_pred['y'] = h2o_glm_predictions
test_pred.to_csv('h2o_glm_predictions.csv',index=False)
