用于微调的tidymodel示例仍在运行。

Question

我是tidymodel包的新手。我试图了解如何微调许多模型，我找到了一个示例。我在运行它，然后在这个步骤，

grid_ctrl <-
   control_grid(
      save_pred = TRUE,
      parallel_over = "everything",
      save_workflow = TRUE
   )

grid_results <-
   all_workflows %>%
   workflow_map(
      seed = 1503,
      resamples = concrete_folds,
      grid = 25,
      control = grid_ctrl
   )

代码继续运行，在运行一个半小时后，我终于得到了以下消息的结果：

x The workflow requires packages that are not installed: 'ranger'. Skipping this workflow.

跑这么长时间是很正常的吗？我知道有12种模型用于调优和评估，但我不认为这需要很长时间。

在呈现书时，我们使用GitHub操作，在本节结尾上我们注意到：

同时使用3名工人，估计过程用了1.6小时。

但是，您不应该得到这些错误；请确保已经安装了所有的正确版本。
