Lines 39 to 47 in df1178d

	def process_ground_truth(item):
	if "reward_model" in item and "ground_truth" in item["reward_model"]:
	try:
	item["reward_model"]["ground_truth"] = json.loads(item["reward_model"]["ground_truth"])
	except:
	pass
	return item
	dataset= dataset.map(process_ground_truth)

During data processing, the use of map unintentionally introduced extra fields into the ground_truth field of the code data. These additional fields caused incorrect code sandbox selection, leading to unexpected bugs.
