使用clean_link_geo函数的过程中，出现报错：AttributeError: 'GeoSeries' object has no attribute 'is_closed'，问下是什么原因？ |

可能是geopandas或者shapely的版本低了 |

您好，我的输入路网是carla仿真环境town12的路网，轨迹序列是自己生成的。由于town12地图太大，因此我只生成了部分区域的轨迹，并且想将生成的轨迹序列匹配到路网上。现在的问题是，设置gps buffer为120，top_k为20，匹配过程超级慢。轨迹序列序列长度20025个，匹配时间需要半小时以上。想请问一下有没有可以加速的方法？或者将路网分段成较大区域之类的方法？ |

好的，我分批匹配一下，设置top_k大一些。 |

最好直接从carla导出 |

因为在匹配之前还要进行其他操作，所以不能从carla里面导出。 |

carla导出也不影响你匹配前做操作呀 |

主要是我现在任务的需求是：输入我生成的轨迹，输出轨迹投影在路网上的点。所以不能用直接导出的轨迹做匹配。 |
