Question about creating Kitti-format data

[shb9793]

When I activate the mmdetection3d virtual environment, and run the following code:

python tools/dataset_converter/dair2kitti.py --source-root ./data/DAIR-V2X/cooperative-vehicle-infrastructure/infrastructure-side \
    --target-root ./data/DAIR-V2X/cooperative-vehicle-infrastructure/infrastructure-side \
    --split-path ./data/split_datas/cooperative-split-data.json \
    --label-type lidar --sensor-view infrastructure --no-classmerge

python tools/dataset_converter/dair2kitti.py --source-root ./data/DAIR-V2X/cooperative-vehicle-infrastructure/vehicle-side \
    --target-root ./data/DAIR-V2X/cooperative-vehicle-infrastructure/vehicle-side \
    --split-path ./data/split_datas/cooperative-split-data.json \
    --label-type lidar --sensor-view vehicle --no-classmerge

All of the output is shown below:

================ Start to Convert ================
================ Start to Copy Raw Data ================

Other than copying the dataset, other operations seem to be terminated. May I know what is the reason?

How long does the entire data conversion process take? Maybe the code has no errors, but the entire conversion process is not visualized?
