Loads previously saved grid with all it's models from the same folder
Returns a reference to the loaded Grid.
h2o.loadGrid(grid_path, load_params_references = FALSE)
grid_path |
A character string containing the path to the file with the grid saved. |
load_params_references |
A logical which if true will attemt to reload saved objects referenced by grid parameters (e.g. training frame, calibration frame), will fail if grid was saved without referenced objects. |
