Hi everyone, based on previous challenges: detectron2 has been one of the most used libraries for submissions.
- We are releasing pre-trained models for making it easier to get started with your first submission!
- The training notebook now has submission interfaces as well (for both quick & active participation directly from Colab)
Thanks for the contributions by @jyot_makadiya and @jyotish
