EfficientDet (PyTorch)

A PyTorch implementation of EfficientDet.

It is based on the

official Tensorflow implementation by Mingxing Tan and the Google Brain team
paper by Mingxing Tan, Ruoming Pang, Quoc V. Le EfficientDet: Scalable and Efficient Object Detection

There are other PyTorch implementations. Either their approach didn't fit my aim to correctly reproduce the Tensorflow models (but with a PyTorch feel and flexibility) or they cannot come close to replicating MS COCO training from scratch.

Aside from the default model configs, there is a lot of flexibility to facilitate experiments and rapid improvements here -- some options based on the official Tensorflow impl, some of my own:

BiFPN connections and combination mode are fully configurable and not baked into the model code
BiFPN and head modules can be switched between depthwise separable or standard convolutions
Activations, batch norm layers are switchable via arguments (soon config)
Any backbone in my timm model collection that supports feature extraction (features_only arg) can be used as a bacbkone.
- Currently this is includes to all models implemented by the EficientNet and MobileNetv3 classes (which also includes MNasNet, MobileNetV2, MixNet and more). More soon...

Updates / Tasks

Latest results in and training goal achieved. Slightly bested the TF model mAP results for D0 model. This model uses:

typical PyTorch symmetric padding (instead of TF compatible SAME)
my PyTorch trained EfficientNet-B0 as the pretrained starting weights (from timm)
BiFPN/Head layers without any redundant conv/BN bias layers (slightly fewer params 3877763 vs 3880067)

Pretrained weights added for this model efficientdet_d0 (Tensorflow port is tf_efficientdet_d0)

2020-05-27

A D0 result in, started before last improvements: Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.331
Another D0 and D1 running with the latest code.

2020-05-22 / 23

A bunch of changes:

COCO eval per epoch for better selection of checkpoints while training, works with distributed
optimizations to both train and inference that should see small throughput gains
doing the above, attempted to torchscript the full training loss + anchor labeler but ran into problems so had to back out part way due messy hacks or weird AMP issues causing silent bad results. Hopefully in PyTorch 1.6 there will be less TS issues.
updated results after clipping boxes, now pretty much exact match to official, even slightly better on a few models
added model factory, pretrained download, cleanup model configs
setup.py, pypi release

2020-05-04

Initial D1 training results in -- close but not quite there. Definitely in reach and better than any other non-official EfficientDet impl I've seen.

Biggest missing element is proper per-epoch mAP validation for better checkpoint selection (than loss based). I was resisting doing full COCO eval because it's so slow, but may throw that in for now...

D1: Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.382

Previous D0 result: Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.324

2020-05-02

First decent MSCOCO training results (from scratch, w/ pretrained classification backbone weights as starting point). 32.4 mAP for D0. Working on improvements and D1 trials still running.

2020-04-15

Taking a pause on training, some high priority things came up. There are signs of life on the training branch, was working the basic augs before priority switch, loss fn appeared to be doing something sane with distributed training working, no proper eval yet, init not correct yet. I will get to it, with SOTA training config and good performance as the end goal (as with my EfficientNet work).

2020-04-11

Cleanup post-processing. Less code and a five-fold throughput increase on the smaller models. D0 running > 130 img/s on a single 2080Ti, D1 > 130 img/s on dual 2080Ti up to D7 @ 8.5 img/s.

2020-04-10

Replace generate_detections with PyTorch impl using torchvision batched_nms. Significant performance increase with minor (+/-.001 mAP) score differences. Quite a bit faster than original TF impl on a GPU now.

2020-04-09

Initial code with working validation posted. Yes, it's a little slow, but I think faster than the official impl on a GPU if you leave AMP enabled. Post processing needs some love.

Core Tasks

Possible Future Tasks

Usage

Environment Setup

Tested in a Python 3.7 or 3.8 conda environment in Linux with:

PyTorch 1.4
PyTorch Image Models (timm) 0.1.20, pip install timm or local install from (https://github.com/rwightman/pytorch-image-models)
Apex AMP master (as of 2020-04)

NOTE - There is a conflict/bug with Numpy 1.18+ and pycocotools, force install numpy <= 1.17.5 or the coco eval will fail, the validation script will still save the output JSON and that can be run through eval again later.

Run Inference

TODO: Need an inference script

Run Training

./distributed_train.sh 2 /mscoco --model tf_efficientdet_d0 -b 16 --amp --lr .04 --warmup-epochs 5 --sync-bn --opt fusedmomentum --fill-color mean --model-ema

NOTE:

Training script currently defaults to a model that does NOT have redundant conv + BN bias layers like the official models, set correct flag when validating.
I've only trained with img mean (--fill-color mean) as the background for crop/scale/aspect fill, the official repo uses black pixel (0) (--fill-color 0). Both likely work fine.
The official training code uses EMA weight averaging by default, it's not clear there is a point in doing this with the cosine LR schedule, I find the non-EMA weights end up better than EMA in the last 10-20% of training epochs
The default h-params is a very close to unstable (exploding loss), don't try using Nesterov momentum. Try to keep the batch size up, use sync-bn.

Examples of Training / Fine-Tuning on Alternate Datasets

Alex Shonenkov has a clear and concise Kaggle kernel which illustrates fine-tuning these models for detecting wheat heads: https://www.kaggle.com/shonenkov/training-efficientdet
If you have a good example script or kernel training these models with a different dataset, feel free to notify me for inclusion here...

Results

My Training

EfficientDet-D0

Latest training run with .336 for D0 (on 4x 1080ti): ./distributed_train.sh 4 --model efficientdet_d0 -b 22 --amp --lr .12 --sync-bn --opt fusedmomentum --warmup-epochs 5 --lr-noise 0.4 0.9 --model-ema --model-ema-decay 0.9999

These hparams above resulted in a good model, a few points:

the mAP peaked very early (epoch 200 of 300) and then appeared to overfit, so likely still room for improvement
I enabled my experimental LR noise which tends to work well with EMA enabled
the effective LR is a bit higher than official. Official is .08 for batch 64, this works out to .0872
drop_path (aka survival_prob / drop_connect) rate of 0.1, which is higher than the suggested 0.0 for D0 in official, but lower than the 0.2 for the other models
longer EMA period than default
