We invite you to upgrade your algorithm library to OpenMMLab 2.0 using [MMEngine](https://github.com/open-mmlab/mmengine), which can be used for both research and commercial purposes. If you have any questions, please feel free to join us on the OpenMMLab Discord at https://discord.gg/amFNsyUBvm or add me on WeChat (van-sin) and I will invite you to the OpenMMLab WeChat group.
