Reproduces the problem - code sample

cd mmdetection3d/tools ; /usr/bin/env /opt/conda/bin/python /root/.vscode-server/extensions/ms-python.debugpy-2024.0.1-linux-x64/bundled/libs/debugpy/adapter/../../debugpy/launcher 49601 -- mmdetection3d/tools/train_debug.py mmdetection3d/configs/parta2/parta2_base.py

Reproduces the problem - error message

no error message, just VSC debugger is stucked

Additional information

There is custom config file and kitti dataset, and training process goes without any errors.
However, when I run the same code on VSC debugger, code always stucked (or pending?) on the line below.
