filter configuration in the ingolstadt.yaml file

[gcordova19]

The issue I am facing is related to the selection of the time window in the ingolstadt.yaml file. I have followed your instructions and configured the file with the correct path. Additionally, I have added a start time related to the bus_signals_20180810150607.json file. However, I am uncertain about how to correctly configure the time filter.

Currently, I am using the following values in the ingolstadt.yaml file:

paths:
source_sensor_data_directory: "/storage/d/a2d2-preview/camera_lidar/20180810_150607"
source_bus_signals_filepath: "/storage/d/a2d2-preview/camera_lidar/20180810_150607/bus/bus_signals_20180810150607.json"
source_sensor_configuration_filepath: "/storage/d/a2d2-preview/camera_lidar/20180810_150607/cams_lidars.json"
target_directory: "/storage/d/a2d2-preview/camera_lidar/20180810_150607_output"
#start_timestamp: 1533906470
#stop_timestamp: 1554121653

The problem manifests with the errors I encounter when running the program. When I remove the time filter, the execution halts and displays the following error messages:

It appears that this problem is related to the time filter configuration in the ingolstadt.yaml file. I would greatly appreciate your guidance on how to correctly set up this time filter so that the program runs smoothly.

This log looks like something went wrong; however, the conversion exited sanely (see line 3).

Concerning the ingolstadt.yaml config and the timestamp filter, make sure to indent them correctly:

filter:
  start_timestamp: 1533906480
  stop_timestamp: 1554121568

Does the conversion work without timestamp-based filters? Does it generate a file named driving_dataset.bag in your output folder?

The preview datasets are pretty short anyway (80 images ~2.6s) and the defined timestamp filters must be within the time domain of the bus (otherwise it will fail). Can you test, if the conversion works on the full Ingolstadt dataset?
