for example, when i load the map in osa format file that was saved before, it reports:terminate called after throwing an instance of 'boost::archive::archive_exception' what(): input stream error Aborted (core dumped) has anyone encountered a similar problem and how did you solve it, many thanks

@aboluo I have exactly the same issue when trying to load a previously saved map. Have you found a fix for this?

@RaduCorcodel what is the size of .osa file?

RaduCorcodel commented 3 months ago

@arjunskumar size on disk is 92MB

arjunskumar commented 3 months ago

@RaduCorcodel can I have your config file of loading the map ?

RaduCorcodel commented 3 months ago

@arjunskumar Of course. I'm using this:

@RaduCorcodel is your map1.osa located in .ros folder?

RaduCorcodel commented 3 months ago

Alas, no. I'm not using ROS. Should it be in the .ros folder? I did a little poking around and it looks like it exits in the middle of writing the .osa file. I start to believe the archive is corrupted

arjunskumar commented 3 months ago

@RaduCorcodel can you share the .osa file ?
