load_experiment(PKL_NAME=None, PREFIX=None)
¶
Loads the experiment from a pickle file.
If PKL_NAME is None and PREFIX is not None, the experiment is loaded based on the PREFIX
using the get_experiment_filename function.
If the spot tuner object and the fun control dictionary do not exist, an error is thrown.
If the design control, surrogate control, and optimizer control dictionaries do not exist, a warning is issued
and None
is assigned to the corresponding variables.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
PKL_NAME |
str
|
Name of the pickle file. Defaults to None. |
None
|
PREFIX |
str
|
Prefix of the experiment. Defaults to None. |
None
|
Returns:
Name | Type | Description |
---|---|---|
spot_tuner |
object
|
The spot tuner object. |
fun_control |
dict
|
The function control dictionary. |
design_control |
dict
|
The design control dictionary. |
surrogate_control |
dict
|
The surrogate control dictionary. |
optimizer_control |
dict
|
The optimizer control dictionary. |
Notes
The corresponding save_experiment function is part of the class spot.
Examples:
>>> from spotpython.utils.file import load_experiment
>>> spot_tuner, fun_control, design_control, _, _ = load_experiment("spot_0_experiment.pickle")
