Inconsistent Handling of Config ID in Benchmark Class

[LabChameleon]

Hi Everyone,

the config_id is handled inconsistently in the query and get_config method. In the former it is converted into a string and in the latter it is not.

Please compare:

LCBench/api.py

Lines 31 to 39 in 17e6375

	def query(self, dataset_name, tag, config_id):
	"""Query a run.
	Keyword arguments:
	dataset_name -- str, the name of the dataset in the benchmark
	tag -- str, the tag you want to query
	config_id -- int, an identifier for which run you want to query, if too large will query the last run
	"""
	config_id = str(config_id)

versus

LCBench/api.py

Lines 108 to 112 in 17e6375

	def get_config(self, dataset_name, config_id):
	"""Returns the configuration of a run specified by dataset name and config id"""
	if dataset_name not in self.dataset_names:
	raise ValueError("Dataset name not found.")
	return self.data[dataset_name][config_id]["config"]
