We provide a collection of detection models pre-trained on the
[COCO 2017 dataset](http://cocodataset.org). These models can be useful for
out-of-the-box inference if you are interested in categories already in those
datasets. You can try it in our inference
[colab](../colab_tutorials/inference_tf2_colab.ipynb)

They are also useful for initializing your models when training on novel
datasets. You can try this out on our few-shot training
[colab](../colab_tutorials/eager_few_shot_od_training_tf2_colab.ipynb).

Please look at [this guide](running_on_mobile_tf2.md) for mobile inference.

Finally, if you would like to train these models from scratch, you can find the
model configs in this [directory](../configs/tf2) (also in the linked
`tar.gz`s).
