在這里，我有一個(gè)使用生成的數(shù)據(jù)訓(xùn)練的增強(qiáng)決策樹，并保存為est：from sklearn.datasets import make_blobsimport pandas as pdimport tensorflow as tf#creates an input function for a tf modeldef make_input_fn(X, Y, n_epochs=None, shuffle=True, verbose=False):    batch_len = len(Y)    def input_fn():        dataset = tf.data.Dataset.from_tensor_slices((dict(X), Y))        if shuffle:            dataset = dataset.shuffle(batch_len)        # For training, cycle thru dataset as many times as need (n_epochs=None).        dataset = dataset.repeat(n_epochs)        #dividing data into batches        dataset = dataset.batch(batch_len)        return dataset    return input_fn#making datatrainX, trainY = make_blobs(n_samples=10, centers=2, n_features=3, random_state=0)#xValstrainX = pd.DataFrame(trainX)trainX.columns = ['feature{}'.format(num) for num in trainX.columns]#yValstrainY = pd.DataFrame(trainY)trainY.columns = ['flag']# Defining input functiontrain_input_fn = make_input_fn(trainX, trainY)#defining tf feature columnsfeature_columns=[]for feature_name in list(trainX.columns):    feature_columns.append(tf.feature_column.numeric_column(feature_name,dtype=tf.float32))    #creating the estimatorn_batches = 1est = tf.estimator.BoostedTreesClassifier(feature_columns, n_batches_per_layer=n_batches)est.train(train_input_fn, max_steps=10)我想使用該模型根據(jù)一行訓(xùn)練數(shù)據(jù)進(jìn)行預(yù)測(cè)以用于測(cè)試目的；像這樣的事情：res = est.predict(trainX.loc[0])但是，我很難弄清楚如何去做。
