：元组索引超出范围

Question

我不确定这是怎么回事 直到该单元格似乎都可以工作。我正在呼出0，所以看不到问题

代码：

# Training LSTM model

 lstm_model=Sequential()
 lstm_model.add(LSTM(units=50,return_sequences=True,input_shape= 
 (x_train_data.shape[1],1)))
 lstm_model.add(LSTM(units=50))
 lstm_model.add(Dense(1))

 inputs=new_dataset[len(new_dataset)-len(valid_data)-60:].values
 inputs=inputs.reshape(-1,1)
 inputs=scaler.transform(inputs)

 lstm_model.compile(loss='mean_squared_error',optimizer='adam')

 lstm_model.fit(x_train_data,y_train_data,epochs=1,
 batch_size=1,verbose=2)

错误：

           ----------------------------------------------------------

       9 predicted_closing_price=scaler.
