Returns:

output path for the experiment

Return type:

set_up_stateful_fields()

Post configuration steps for stateful fields such as output_path in the derived class. This method should be overridden in the derived class.

start()

Start the experimen. This will - cache NNTOOL_OUTPUT_PATH and NNTOOL_OUTPUT_PATH_DATE into environment variables, which means the later launched processes would inherit these variables. - create the output path if it does not exist.
