Before Change

    // 3.generate input data for model

                       [test[feat.name].values for feat in dense_feature_list]

After Change

    // 2.set hashing space for each sparse field,and record dense feature field name

    fixlen_feature_columns = [SparseFeat(feat, 1000, use_hash=True, dtype="string")  // since the input is string
                              for feat in sparse_features] + [DenseFeat(feat, 1, )
                          for feat in dense_features]

    linear_feature_columns = fixlen_feature_columns
    dnn_feature_columns = fixlen_feature_columns
    fixlen_feature_names = get_fixlen_feature_names(linear_feature_columns + dnn_feature_columns, )

    // 3.generate input data for model

    train, test = train_test_split(data, test_size=0.2)
    train_model_input = [train[name] for name in fixlen_feature_names]
