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,

HRMapNet/projects/configs/hrmapnet/hrmapnet_maptrv2_nusc_r50_24ep.py

Line 76 in 197f340

save_map_path=None,

and use this function to save the map when it is built well,

HRMapNet/projects/mmdet3d_plugin/hrmap/global_map.py

Line 244 in 197f340

def save_global_map(self):

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.
