This is the tf2.0 version of efficientdet.

2. Pretrained EfficientDet Checkpoints

The checkpoints and results is here.

3. Saved model

python3 -m inferences.efficientdet --input_size=512x512

Note! We should add the checkpoints to pretrained_weights. The default model is efficientdet-d0, if you want to use others, you should modify the configs/efficiendet_configs.py.

The new efficientdet-d0 implementation run around 26ms, faster than official TF version, because we use combined_non_maximum instead the official version NMS (the input size is 512x512, the official efficientdet-d0 is 1280x1920). Note, run this test on P4000 GPU, ubuntu 18.04.

4. Tensorrt

python3 -m inferences.efficientdet --mode=FP16 --saved_model_dir=./saved_model/efficientdet-d0/1  --output_dir=./trt_model/efficientdet-d0/1

Note, only support FP16 and FP32.

4. Run demo

python3 demo.py --saved_model ./saved_model/efficientdet-d0/1 --video_path xxx.mp4
