If a SMAC run was interrupted or you want to extend its computation- or time-limits, it can be restored and continued. To restore or continue a previous SMAC run, use the --restore_state FOLDER option in the commandline. If you want to increase computation- or time-limits, change the scenario-file specified with the --scenario SCENARIOFILE option (not the one in the folder to be restored). Restarting a SMAC run that quit due to budget-exhaustion will do nothing, because the budget is still exhausted.


Changing any other options than output_dir, wallclock_limit, runcount_limit or tuner-timeout in the scenario-file is NOT intended and will likely lead to unexpected behaviour!

For an example of restoring states from within your Python code, there is an implementation with the Branin-example in “examples/quickstart/branin/”.
