我究竟做错了什么？意想不到的意外

Question

我在 python 中测试 ARIMA 时间序列模型，运行中出现“IndentationError: unexpected unindent”消息。我试过在几个点上缩进和取消缩进都无济于事。所以我希望有人能指出我正确的方向。请查看下面的代码，它会导致以下错误：

  File "<ipython-input-64-8f9bf4ba4a44>", line 13
    results = mod.fit()
                       ^
IndentationError: unexpected unindent

for param in pdq:
    for param_seasonal in seasonal_pdq:
        try:
            mod = sm.tsa.statespace.SARIMAX(y,
                                            order=param,
                                            
seasonal_order=param_seasonal,
                                            
enforce_stationarity=False,

enforce_invertibility=False)
            
results = mod.fit()

print('ARIMA{}x{}12 - AIC:{}'.format(param, param_seasonal, 
results.aic))
        except:
            continue

Answer 1

错误消息尽可能清楚：您的缩进级别错误。以下作品：

for param in pdq:
    for param_seasonal in seasonal_pdq:
        try:
            mod = sm.tsa.statespace.SARIMAX(
                 y,
                 order=param,
                 seasonal_order=param_seasonal,
                 enforce_stationarity=False, enforce_invertibility=False
            )
            results = mod.fit()

            print('ARIMA{}x{}12 - AIC:{}'.format(
                 param,
                 param_seasonal,
                 results.aic
            ))
        except:
            continue

Answer 2

try 块有问题，try 块应该是这样的

    try:
        mod = sm.tsa.statespace.SARIMAX(
             y,
             order=param,
             seasonal_order=param_seasonal,
             enforce_stationarity=False, enforce_invertibility=False
        )
        results = mod.fit()

        print('ARIMA{}x{}12 - AIC:{}'.format(
             param,
             param_seasonal,
             results.aic
        ))
    except:
        continue

还建议使用任何现代 IDE 来消除缩进问题，
