HRMapNet Global map construction

Hi team, Thanks for your work! I want to build my global map features by myself and obtain the pt files, i.e. training and testing map, how can I modify the model?

Hi! You can set the save_map_path here, https://github.com/HXMap/HRMapNet/blob/197f3407e130ced435db40bff91954286d480ce2/projects/configs/hrmapnet/hrmapnet_maptrv2_nusc_r50_24ep.py#L76 and use this function to save the map when it is built well, https://github.com/HXMap/HRMapNet/blob/197f3407e130ced435db40bff91954286d480ce2/projects/mmdet3d_plugin/hrmap/global_map.py#L244

你好，采用分布式训练，你是如何在不同进程间更新同一个global_map的？在代码里没看到啊。

Hi, the global map in different GPUs are not shared or merged. I tried merging them, but the results were not better.
