## What it is
A PyTorch re-implementation of Google's EfficientDet object detection model with pretrained weights matching near-SOTA accuracy at real-time speeds. It includes training scripts, evaluation benchmarks, and model scales D0-D7.

## Use cases
- train a custom object detection model in pytorch
- run real-time object detection with pretrained efficientdet weights
- benchmark efficientdet mAP and FPS on my GPU
- detect objects in images using efficientdet D0-D7
- fine-tune efficientdet on my own dataset
- convert efficientdet from tensorflow to pytorch

## When to choose
- you want EfficientDet in PyTorch with pretrained weights close to official accuracy
- you need real-time object detection with a range of model sizes
- you want to fine-tune a detector on a custom dataset with provided tutorials

## When to avoid
- you need the latest maintained implementation or newest model architectures
- you require TensorFlow or the official Google automl toolchain
- you need production support or frequent updates - the repo has not seen releases since 2021

## Facets
- artifact type: library
- maturity: maintenance
- function: machine-learning, deep-learning, computer-vision, image-processing
- domain: computer-vision, deep-learning, machine-learning, image-processing
- platform: python, cross-platform
- tags: object-detection, efficientdet, efficientnet, bifpn, pytorch, pretrained-weights, real-time-inference, gpu, linux
