Keras 错误：TypeError：'int' 对象不可迭代

Question

CONST_TRAINTING_SEQUENCE_LENGTH = 12

CONST_TESTING_CASES = 5

def dataNormalization(data):

    return [(datum - data[0]) / data[0] for datum in data]

def dataDeNormalization(data, base):

    return [(datum + 1) * base for datum in data]

def getDeepLearningData(ticker):

    # Step 1. Load data

    data = pandas.read_csv('/Users/yindeyong/Desktop/Django_Projects/pythonstock/data/Intraday/' + ticker + '.csv')[

        'close'].tolist()

    # Step 2. Building Training data

    dataTraining = []

    for i in range(len(data) - CONST_TESTING_CASES * CONST_TRAINTING_SEQUENCE_LENGTH):

        dataSegment = data[i:i + CONST_TRAINTING_SEQUENCE_LENGTH + 1]

        dataTraining.append(dataNormalization(dataSegment))

    dataTraining = numpy.array(dataTraining)

    numpy.random.shuffle(dataTraining)

    X_Training = dataTraining[:, :-1]

    Y_Training = dataTraining[:, -1]

    # Step 3. Building Testing data

    X_Testing = []

    Y_Testing_Base = []

    for i in range(CONST_TESTING_CASES, 0, -1):

        dataSegment = data[-(i + 1) * CONST_TRAINTING_SEQUENCE_LENGTH:-i * CONST_TRAINTING_SEQUENCE_LENGTH]

        Y_Testing_Base.append(dataSegment[0])

        X_Testing.append(dataNormalization(dataSegment))

    Y_Testing = data[-CONST_TESTING_CASES * CONST_TRAINTING_SEQUENCE_LENGTH:]

    X_Testing = numpy.array(X_Testing)

    Y_Testing = numpy.array(Y_Testing)

    # Step 4. Reshape for deep learning

    X_Training = numpy.reshape(X_Training, (X_Training.shape[0], X_Training.shape[1], 1))

我有一个错误：

文件“/Users/yindeyong/Desktop/Django_Projects/envs/stockenv/lib/python3.6/site-packages/keras/engine/base_layer.py”，第147行，在init batch_size中，) + tuple(kwargs['input_shape' ]) TypeError: 'int' 对象不可迭代

我试图将input_shape=1更改 为input_shape=(1,)，然后又出现了另一个错误：

ValueError：输入 0 与层 lstm_1 不兼容：预期 ndim=3，发现 ndim=2

Answer 1

LSTM 是处理序列的循环网络序列必须具有length和features，您的输入形状必须包含以下两个：input_shape=(length, features).您的数据也必须相应地进行整形，使用(sequences, length, features).对于可变长度，您可以使用input_shape=(None,features).

Answer 2

您不能传递input_shape整数，它必须是可迭代的，例如(1,). 看起来你的 X_training 形状不对。您必须重塑它，使其适合 input_shape。
