尝试通过rnn来练习加密货币预测

Question

ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, (<class 'list'> containing values of types {"<class 'numpy.float64'>"})

之后，我添加了以下代码：

train_y= np.asarray(train_y) validation_y= np.asarray(validation_y)
train_y= np.asarray(train_y) validation_y= np.asarray(validation_y)

history = model.fit(
    train_x, train_y,
    batch_size=BATCH_SIZE,
    epochs=EPOCHS,
    validation_data=(validation_x, validation_y),
    callbacks=[tensorboard, checkpoint])

但我收到此错误：

File "C:/Users/Enock/.spyder-py3/cryptoRnn.py", line 174
train_y= np.asarray(train_y) validation_y= np.asarray(validation_y)
                                        ^
SyntaxError: invalid syntax...

我该怎么办？
