这个 label_map = {'positive': 1,'negative': -1,'uncertainty': 0} labels是1,-1,和0，但是总给我报错KeyError: 1 怎么回事

根据你提供的 `label_map` 字典的定义，它将 'positive' 映射到 1，'negative' 映射到 -1，'uncertainty' 映射到 0。

然而，根据你描述的错误信息 `KeyError: 1`，看起来发生了一个键错误。这意味着在尝试使用 `label_map` 字典的时候，没有找到键为 1 的映射。

根据你之前提到的 `labels` 是一个包含 1、-1 和 0 的列表，代码应该是这样的:

label_map = {'positive': 1, 'negative': -1, 'uncertainty': 0}
labels = [1, -1, 0]

mapped_labels = [label_map[label] for label in labels]

请确保 `labels` 列表中的元素与 `label_map` 字典中的键一致，以正确进行映射。如果仍然遇到问题，请检查一下输入数据是否正确。

这段Python代码是KalmanFilter类的初始化方法。在这个方法中，首先会检查dim_x、dim_z和dim_u是否符合要求，如果不符合就会抛出ValueError异常。然后会根据参数的值初始化KalmanFilter对象的各个属性，包括状态量的维度dim_x、观测量的维度dim_z、控制量的维度dim_u。初始化时，状态量x被初始化为一个dim_x行1列的零向量，不确定性协方差P被初始化为dim_x阶单位矩阵，过程不确定性Q也被初始化为dim_x阶单位矩阵。控制转移矩阵B、状态转移矩阵F、测量函数H、状态不确定性R、过程-测量交叉相关M、增长记忆控制参数_alpha_sq、测量残差z、卡尔曼增益K、残差y、系统不确定性S和其逆矩阵SI等都被初始化为相应的大小的零矩阵或数组。这个类还包含一个求逆矩阵的方法inv。

model_list <- prophet(WHO_data_list, growth = "logistic", changepoints = None, n_changepoints = 25, changepoint_range = 0.8, yearly_seasonality = T, weekly_seasonality = F, daily_seasonality = F, holidays= None, seasonality_mode = 'multiplicative', seasonality_prior_scale = 10.0, holidays_prior_scale = 10.0, changepoint_prior_scale = 0.05, mcmc_samples = 0, interval_width = 0.95, uncertainty_samples = 1000, stan_backend = None)

这是一个使用 Prophet 模型对 WHO_data_list 进行时间序列预测的代码。在该模型中，使用了逻辑增长模型（growth = "logistic"），没有设置特殊的变化点（changepoints = None），设置了25个变化点（n_changepoints = 25），变化点范围为80%（changepoint_range = 0.8），启用了年度季节性（yearly_seasonality = T），未启用周季节性和日季节性（weekly_seasonality = F, daily_seasonality = F），没有添加节假日信息（holidays= None），季节性模式为乘法模式（seasonality_mode = 'multiplicative'），季节性先验比例为10.0（seasonality_prior_scale = 10.0），节假日先验比例为10.0（holidays_prior_scale = 10.0），变化点先验比例为0.05（changepoint_prior_scale = 0.05），采样次数为0（mcmc_samples = 0），置信区间为95%（interval_width = 0.95），不确定性采样次数为1000（uncertainty_samples = 1000），后端使用默认值（stan_backend = None）。
