 This is an unofficial demo for [https://github.com/open-mmlab/mmdetection](https://github.com/open-mmlab/mmdetection).
-This space demonstrates the use of an integration of Vision pretained models from Open MMlab and hugging face hub. Model configurations and checkpoints are uploaded to hugging face space and can be used for inference directly from [MMdetection](https://github.com/open-mmlab/mmdetection) library
