本文展示了使用时序卷积网络（TCN）进行时间序列预测的全过程，包含详细的注释。整个过程主要包括：数据导入、数据清洗、结构转化、建立TCN模型、训练模型（包括动态调整学习率和earlystopping的设置）、预测、结果展示、误差评估等完整的时间序列预测流程。

滞后扩充数据

dataframe1 = pd.DataFrame()
num_hour = 16
for i in range(num_hour,0,-1):
    dataframe1['t-'+str(i)] = series.shift(i)
dataframe1['t'] = series.values
dataframe3=dataframe1.dropna()
dataframe3.index=range(len(dataframe3))
