evaluation
Since I only found an instruction dataset DUOMO-Lab/Transgpt_sft_v2 in the field of traffic, in order to remove the influence of the base model, I used the data in llama3.1-8b-instruc for fine-tuning and compared and evaluated our model. The evaluation method is: use GPT4 on the validation set of each dataset to compare good, tie, and loss. The evaluation results are as follows

私人交通工具的发展对经济有着深远的影响。首先,私人交通工具的发展可以促进汽车制造业的繁荣。随着私人交通工具的需求增加,汽车制造商将面临更大的市场需求,从而带动产业链的发展,创造就业机会,增加经济收入。其次,私人交通工具的发展也会带动相关
业的发展,如燃料供应、维修服务和保险等。这些行业的发展将为经济增长做出贡献。此外,私人交通工具的发展还会促进城市交通的便利性,提高人们的生活质量,从而带动消费,刺激经济发展。然而,私人交通工具的发展也会带来一些负面影响,如交通拥堵和环境
染等问题。因此,政府需要采取相应的政策措施来平衡经济发展和环境保护的需要。总的来说,私人交通工具的发展对经济有着重要的影响,需要综合考虑各种因素进行合理规划和管理。
