Batch Run Example Process Timeout Failure

[jzhu1234]

When I execute the UUV batch run example "run_grid_search", all of the processes timeout before the simulation process is finished. In other words, it seems to crash or not respond to the roscore I have launched. What is the reason for this?

I have roscore launched on the localhost, and I am using the cost_fcn parameters in uuv_smac_example because no cost_fcn was specified in the example_grid_search.yml file, which was causing a KeyError.
