python - 参数 GridSearchCV

Question

我正在尝试优化我的 sarimax 模型，但在尝试使用 GridSearchCV 参数函数时遇到了困难，您能帮帮我吗？我想为我的模型制作多个模型的网格：

    pipe = pipeline.Pipeline([
    ("Month", ppc.FourierFeaturizer(m=251, k=10)),
    ("weekly", ppc.FourierFeaturizer(m=63, k=8)),
    ("arima", arima.AutoARIMA(  stepwise = True, trace = 1, error_action = "ignore",
                                seasonal = False, #because we use Fourier
                                suppress_warnings = True))
    ])



    pipe = pipeline.Pipeline([
    ("Month", ppc.FourierFeaturizer(m=[150,250,300], k=8,7,10)),
    ("weekly", ppc.FourierFeaturizer(m=40,63,80, k=4,8,9)),
    ("arima", arima.AutoARIMA(  stepwise = True, trace = 1, error_action = "ignore",
                                seasonal = False, #because we use Fourier
                                suppress_warnings = True))
    ]) something like the following
