| # Rerun | ||||
| Rerun is a tool to quickly visualize time series data. It supports all openpilot logs , both the `logMessages` and video logs. | ||||
| 
 | ||||
| [Instructions](https://rerun.io/docs/reference/viewer/overview) for navigation within the Rerun Viewer. | ||||
| 
 | ||||
| ## Usage | ||||
| ``` | ||||
| usage: run.py [-h] [--demo] [--qcam] [--fcam] [--ecam] [--dcam] [--print_services] [--services [SERVICES ...]] [route_or_segment_name] | ||||
| 
 | ||||
| A helper to run rerun on openpilot routes | ||||
| 
 | ||||
| options: | ||||
|   -h, --help                  show this help message and exit | ||||
|   --demo                      Use the demo route instead of providing one (default: False) | ||||
|   --qcam                      Log decimated driving camera (default: False) | ||||
|   --fcam                      Log driving camera (default: False) | ||||
|   --ecam                      Log wide camera (default: False) | ||||
|   --dcam                      Log driver monitoring camera (default: False) | ||||
|   --print_services            List out openpilot services (default: False) | ||||
|   --services [SERVICES ...]   Specify openpilot services that will be logged. No service will be logged if not specified. | ||||
|                               To log all services include 'all' as one of your services (default: []) | ||||
|   --route [ROUTE]             The route or segment name to plot (default: None) | ||||
| ``` | ||||
| 
 | ||||
| Examples using route name to observe accelerometer and qcamera: | ||||
| 
 | ||||
| `./run.py --services accelerometer --qcam --route "a2a0ccea32023010/2023-07-27--13-01-19"` | ||||
| 
 | ||||
| Examples using segment range (more on [SegmentRange](https://github.com/commaai/openpilot/tree/master/tools/lib)): | ||||
| 
 | ||||
| `./run.py --qcam --route "a2a0ccea32023010/2023-07-27--13-01-19/2:4"` | ||||
| 
 | ||||
| ## Cautions: | ||||
| - You can specify `--services all` to visualize all `logMessage`, but it will draw a lot of memory usage and take a long time to log all messages. Rerun isn't ready for logging big number of data. | ||||
| 
 | ||||
| - Logging hevc videos (`--fcam`, `--ecam`, and `--dcam`)  are expensive, and it's recommended to use `--qcam` for optimized performance. If possible, limiting your route to a few segments using `SegmentRange` will speed up logging and reduce memory usage | ||||
| 
 | ||||
| This example draws 13GB of memory: | ||||
| 
 | ||||
| `./run.py --services accelerometer --qcam --route "a2a0ccea32023010/2023-07-27--13-01-19"` | ||||
| 
 | ||||
| 
 | ||||
| ## Openpilot services | ||||
| To list all openpilot services: | ||||
| 
 | ||||
| `./run.py --print_services` | ||||
| 
 | ||||
| Examples including openpilot services: | ||||
| 
 | ||||
| `./run.py --services accelerometer cameraodometry --route "a2a0ccea32023010/2023-07-27--13-01-19/0/q"` | ||||
| 
 | ||||
| Examples including all services: | ||||
| 
 | ||||
| `./run.py --services all --route "a2a0ccea32023010/2023-07-27--13-01-19/0/q"` | ||||
| 
 | ||||
| ## Demo | ||||
| `./run.py --services accelerometer carcontrol caroutput --qcam --demo` | ||||
