2 Data

2.1 Dataset类

2.2 下载文件

2.3 get_dataset

2.4 get_trajectories

trajectory_split暂时略去

# save the test dictionary and the true locations dictionary
        utils.create_dir(self.save_dir)
        with open(os.path.join(self.save_dir, 'test_dictionary_'+self.dataset_name+'_'+self.trajectory_mode+'.json'), 'w') as f:
            json.dump(self.test_dictionary, f)
        with open(os.path.join(self.save_dir, 'true_locations_'+self.dataset_name+'_'+self.trajectory_mode+'.json'), 'w') as f:
            json.dump(self.true_locations, f)
