I want to use EfficientDet model for this competition:4th UG2+ challenge (CVPR 2021) Track 1.1 - Object Detection in the Hazy Condition.
Since many tricks have not been implemented, I forked the source repository (efficientdet-pytorch) created by rwightman.
Compared with original repository, what's new in this repo is shown below:
- BBOX IoU loss (giou, diou, ciou)
- More data augmentation strategies during training:
- noaug、aug、moreaug with Albumentations
- copy and paste strategy
- Multi-scale testing
- Weighted-Boxes-Fusion
- Some ultilities
- augmentation visualization, result visualization
- every-category metrics and confusion matrix (need to clone my another repo:CocoEvalPlus)
There is no denying that the original repo is a great implementation of EfficientDet using PyTorch. I'm not sure whether my modification is suitable for all situations due to the complexity of the repo. It works well in my own case by now.
Example commands for training, validating and testing:
# train
python ./train.py --dataset cocortts --model tf_efficientdet_d0 --num-classes 5 --epochs 15 --lr 0.02 --warmup-epochs 3 --warmup-lr 0.02 --min-lr 0.00001 --lr-cycle-limit 3 --lr-cycle-mul 0.8 --native-amp --pretrained --decay-rate 0.1 -j 8 -b 8 --train-transform-mode moreaug ../
# validate
python ./validate.py --dataset cocortts --model tf_efficientdet_d4 --num-classes 5 -j 8 --pretrained --checkpoint ./output/d4/d4_bs6_moreaug/model_best.pth.tar -b 8 --native-amp --split val --wbf ../
# test
python ./validate.py --dataset cocortts --model tf_efficientdet_d4 --num-classes 5 -j 8 --pretrained --checkpoint /path/to/model -b 8 --native-amp --split test --wbf --results ./d4_best ../You can get more information about parameters for training or validating by option -h. And you can obtain more details about the new repo by contacting with me.
Welcome your discussions or issues!
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
timmmodel collection that supports feature extraction (features_onlyarg) can be used as a bacbkone.
- Add EfficientDet AdvProp-AA weights for D0-D5 from TF impl. Model names
tf_efficientdet_d?_ap
- Add some new model weights with bilinear interpolation for upsample and downsample in FPN.
- 40.9 mAP -
efficientdet_q1(replace prev model at 40.6) - 43.2 mAP -
cspresdet50 - 45.2 mAP -
cspdarkdet53m
- 40.9 mAP -
- Training w/ fully jit scripted model + bench (
--torchscript) is possible with inclusion of ModelEmaV2 fromtimmand previous torchscript compat additions. Big speed gains for CPU bound training. - Add weights for alternate FPN layouts. QuadFPN experiments (
efficientdet_q0/q1/q2) and CSPResDeXt + PAN (cspresdext50pan). See updated table below. Special thanks to Artus for providing resources for training the Q2 model. - Heads can have a different activation from FPN via config
- FPN resample (interpolation) can be specified via config and include any F.interpolation method or
max/avgpool - Default focal loss changed back to
new_focal, use--legacy-focalarg to use the original. Legacy uses less memory, but has more numerical stability issues. - custom augmentation transform and collate fn can be passed to loader factory
timm>= 0.3.2 required, NOTE double check any custom defined model config for breaking change- PyTorch >= 1.6 now required
- add experimental PAN and Quad FPN configs to the existing EfficientDet BiFPN w/ two test model configs
- switch untrained experimental model configs to use torchscript compat bn head layout by default
- set model config to read-only after creation to reduce likelyhood of misuse
- no accessing model or bench .config attr in forward() call chain (for torcscript compat)
- numerous smaller changes that allow jit scripting of the model or train/predict bench
Merged a few months of accumulated fixes and additions.
- Proper fine-tuning compatible model init (w/ changeable # classes and proper init, demoed in train.py)
- A new dataset interface with dataset support (via parser classes) for COCO, VOC 2007/2012, and OpenImages V5/Challenge2019
- New focal loss def w/ label smoothing available as an option, support for jit of loss fn for (potential) speedup
- Improved a few hot spots that squeek out a couple % of throughput gains, higher GPU utilization
- Pascal / OpenImages evaluators based on Tensorflow Models Evaluator framework (usable for other datasets as well)
- Support for native PyTorch DDP, SyncBN, and AMP in PyTorch >= 1.6. Still defaults to APEX if installed.
- Non-square input image sizes are allowed for the model (the anchor layout). Specified by image_size tuple in model config. Currently still restricted to
size % 128 = 0on each dim. - Allow anchor target generation to be done in either dataloader process' via collate or in model as in past. Can help balance compute.
- Filter out unused target cls/box from dataset annotations in fixed size batch tensors before passing to target assigner. Seems to speed convergence.
- Letterbox aware Random Erasing augmentation added.
- A (very slow) SoftNMS impl added for inference/validation use. It can be manually enabled right now, can add arg if demand.
- Tested with PyTorch 1.7
- Add ResDet50 model weights, 41.6 mAP.
A few things on priority list I haven't tackled yet:
- Mosaic augmentation
- bbox IOU loss (tried a bit but so far not a great result, need time to debug/improve)
NOTE There are some breaking changes:
- Predict and Train benches now output XYXY boxes, NOT XYWH as before. This was done to support other datasets as XYWH is COCO's evaluator requirement.
- The TF Models Evaluator operates on YXYX boxes like the models. Conversion from XYXY is currently done by default. Why don't I just keep everything YXYX? Because PyTorch GPU NMS operates in XYXY.
- You must update your version of
timmto the latest (>=0.3), as some APIs for helpers changed a bit.
Training sanity checks were done on VOC and OI
- 80.0 @ 50 mAP finetune on voc0712 with no attempt to tune params (roughly as per command below)
- 18.0 mAP @ 50 for OI Challenge2019 after couple days of training (only 6 epochs, eek!). It's much bigger, and takes a LOONG time, many classes are quite challenging.
- All models updated to latest checkpoints from TF original.
- Add experimental soft-nms code, must be manually enabled right now. It is REALLY slow, .1-.2 mAP increase.
- Add updated TF ported weights for D3 model (better training) and model def and weights for new D7X model (54.3 val mAP)
- Fix Windows bug so it at least trains in non-distributed mode
Add updated D7 weights from Tensorflow impl, 53.1 validation mAP here (53.4 in TF)
New model results, I've trained a D1 model with some WIP augmentation enhancements (not commited), just squeaking by official weights.

Unlike the other tf_ prefixed models this is not ported from (as of yet unreleased) TF official model, but it used
TF ported weights from timm for the pretrained imagenet model as the backbone init, thus it uses SAME padding.
The table below contains models with pretrained weights. There are quite a number of other models that I have defined in model configurations that use various timm backbones.

NOTE: Official scores for all modules now using soft-nms, but still using normal NMS here.
NOTE: In training some experimental models, I've noticed some potential issues with the combination of synchronized BatchNorm (--sync-bn) and model EMA weight everaging (--model-ema) during distributed training. The result is either a model that fails to converge, or appears to converge (training loss) but the eval loss (running BN stats) is garbage. I haven't observed this with EfficientNets, but have with some backbones like CspResNeXt, VoVNet, etc. Disabling either EMA or sync bn seems to eliminate the problem and result in good models. I have not fully characterized this issue.
Tested in a Python 3.7 or 3.8 conda environment in Linux with:
- PyTorch 1.6, 1.7, 1.7.1
- PyTorch Image Models (timm) >= 0.3.2,
pip install timmor local install from (https://github.com/rwightman/pytorch-image-models) - Apex AMP master (as of 2020-08)
NOTE - There is a conflict/bug with Numpy 1.18+ and pycocotools 2.0, force install numpy <= 1.17.5 or ensure you install pycocotools >= 2.0.2

./distributed_train.sh 4 /mscoco --model tf_efficientdet_d0 -b 16 --amp --lr .09 --warmup-epochs 5 --sync-bn --opt fusedmomentum --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.
2007, 2012, and combined 2007 + 2012 w/ labeled 2007 test for validation are supported.

Setting up OpenImages dataset is a commitment. I've tried to make it a bit easier wrt to the annotations, but grabbing the dataset is still going to take some time. It will take approx 560GB of storage space.
To download the image data, I prefer the CVDF packaging. The main OpenImages dataset page, annotations, dataset license info can be found at: https://storage.googleapis.com/openimages/web/index.html
Follow the s3 download directions here: https://github.com/cvdfoundation/open-images-dataset#download-images-with-bounding-boxes-annotations
Each train_<x>.tar.gz should be extracted to train/<x> folder, where x is a hex digit from 0-F. validation.tar.gz can be extracted as flat files into validation/.
Annotations can be downloaded separately from the OpenImages home page above. For convenience, I've packaged them all together with some additional 'info' csv files that contain ids and stats for all image files. My datasets rely on the <set>-info.csv files. Please see https://storage.googleapis.com/openimages/web/factsfigures.html for the License of these annotations. The annotations are licensed by Google LLC under CC BY 4.0 license. The images are listed as having a CC BY 2.0 license.
wget https://github.com/rwightman/efficientdet-pytorch/releases/download/v0.1-anno/openimages-annotations.tar.bz2
wget https://github.com/rwightman/efficientdet-pytorch/releases/download/v0.1-anno/openimages-annotations-challenge-2019.tar.bz2
find . -name '*.tar.bz2' -exec tar xf {} \;
Once everything is downloaded and extracted the root of your openimages data folder should contain:
annotations/<csv anno for openimages v5/v6>
annotations/challenge-2019/<csv anno for challenge2019>
train/0/<all the image files starting with '0'>
.
.
.
train/f/<all the image files starting with 'f'>
validation/<all the image files in same folder>
Training with Challenge2019 annotations (500 classes):
./distributed_train.sh 4 /data/openimages --model efficientdet_d0 --dataset openimages-challenge2019 -b 7 --amp --lr .042 --sync-bn --opt fusedmomentum --warmup-epochs 1 --lr-noise 0.4 0.9 --model-ema --model-ema-decay 0.999966 --epochs 100 --remode pixel --reprob 0.15 --recount 4 --num-classes 500 --val-skip 2
The 500 (Challenge2019) or 601 (V5/V6) class head for OI takes up a LOT more GPU memory vs COCO. You'll likely need to half batch sizes.
The models here have been used with custom training routines and datasets with great results. There are lots of details to figure out so please don't file any 'I get crap results on my custom dataset issues'. If you can illustrate a reproducible problem on a public, non-proprietary, downloadable dataset, with public github fork of this repo including working dataset/parser implementations, I MAY have time to take a look.
Examples:
- 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 (this is out of date wrt to latest versions here)
If you have a good example script or kernel training these models with a different dataset, feel free to notify me for inclusion here...
Latest training run with .336 for D0 (on 4x 1080ti):
./distributed_train.sh 4 /mscoco --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
