How can I run the agent offline？

[Simona0212]

I am interested in the image data collection and processing of your excellent platform.

I notice that your project seems not providing offline configs but offline init method (in GoogleMapAPI class):

def init_offline(self, offline_cfg):
        self.panorama_dir = offline_cfg.PANORAMA_DIR
        self.mapping_path = offline_cfg.GPS_TO_PANO_PATH
        
        if self.panorama_dir != 'None':
            self.offline_pano = True
            print(f'Offline panorama mode is enabled. Panorama dir: {self.panorama_dir}')
        
        if self.mapping_path != 'None':
            self.offline_mapping = True
            print(f'Offline mapping mode is enabled. Mapping path: {self.mapping_path}')
            self.gps_to_pano_mapping = pickle.load(open(self.mapping_path, 'rb'))

        # TODO: add place information

How can I run it offline and what data and configs is required?

Additionally, can I download street view images to local from google maps with your existed pipeline and how can I make it?

Looking foward to your reply and thanks a lot!

Specifically speaking, I find OFFLINE configs in tools/cfgs/base_configs/default.yaml but fail to get access to PANORAMA_DIR and GPS_TO_PANO_PATH. How can I solve it?

PLATFORM:
  STREET_VIEW:
    SIZE: [ 640, 640 ]

    GPS_TO_PANO_PATH: None # /data/projects/VIRL_internal/output/snapshot/vln/gps_pano_mapping.pkl
    # If the distance between two points is less than this value, 
    # they are considered the same point.
    # Otherwise, will call the online method.

Thanks for your question. I will write guidelines for this part.
