wget https://github.com/autowarefoundation/autoware_rosbag2_anonymizer/releases/download/v1.0.0/yolo_config.yamlsudo apt install ros-humble-rosbag2-storage-mcapBefore installing the tool, you should update the pip package manager.
python3 -m pip install pip -Upython3 -m pip install .The tool provides two options to anonymize images in rosbags. You can directly anonymize your ROS2 bag file with option 1 or you can train your own YOLO model with option 2 to improve the results.
- If your ROS 2 bag file includes custom message types from Autoware or any other packages, you should source the their workspaces before running the tool.
source /path/to/your/workspace/install/setup.bash
You should provide the path to the forlder which contains ROS 2 bag files and the output folder to save anonymized bag files. The model is a combination of GroundingDINO, OpenCLIP, YOLO and SegmentAnything anonymize images in rosbags. If you don't want to use pre-trained YOLO model, you can follow the instructions in the second option to train your own YOLO model.
You should set your configuration in config/anonymize_with_unified_model.yaml file.
python3 main.py config/anonymize_with_unified_model.yaml --anonymize_with_unified_modelTo improve the results, you can train your own YOLO model with the dataset created by the unified model.
Check the documentation to see the detailed instructions. Train Your Own YOLO Model
Define prompts in the validation.jsonfile. The tool will use these prompts to detect objects.
You can add your prompts as dictionaries under the prompts key. Each dictionary should have two keys:
prompt: The prompt that will be used to detect the object. This prompt will be blurred in the anonymization process.should_inside: This is a list of prompts that object should be inside. If the object is not inside the prompts, the tool will not blur the object.
{
"prompts": [
{
"prompt": "license plate",
"should_inside": ["car", "bus", "..."]
},
{
"prompt": "human face",
"should_inside": ["person", "human body", "..."]
}
]
}You should set your configuration in the configuration files under config folder according to the usage.
Following instructions will guide you to set each configuration file.

torch.OutOfMemoryError: CUDA out of memory. Tried to allocate 1024.00 MiB. GPU 0 has a total capacity of 10.87 GiB of which 1010.88 MiB is free. Including non-PyTorch memory, this process has 8.66 GiB memory in use. Of the allocated memory 8.21 GiB is allocated by PyTorch, and 266.44 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.
See documentation for Memory Management (https://pytorch.org/docs/stable/notes/cuda.html#environment-variables)This error occurs when the GPU memory is not enough to run the model. You can add the following environment variable to avoid this error.
export PYTORCH_CUDA_ALLOC_CONF=expandable_segments:TrueError 2: Tool is taking too much time to process
The tool might take a significant amount of time to process images, due to the computational complexity of combining multiple models (GroundingDINO, OpenCLIP, YOLO, SegmentAnything).
