Detectron2 Model Zoo and Baselines

Introduction

This file documents a large collection of baselines trained with detectron2 in Sep-Oct, 2019. All numbers were obtained on Big Basin servers with 8 NVIDIA V100 GPUs & NVLink. The speed numbers are periodically updated with latest PyTorch/CUDA/cuDNN versions. You can access these models from code using detectron2.model_zoo APIs.

In addition to these official baseline models, you can find more models in projects/.

How to Read the Tables

The "Name" column contains a link to the config file. Models can be reproduced using tools/train_net.py with the corresponding yaml config file, or tools/lazyconfig_train_net.py for python config files.
Training speed is averaged across the entire training. We keep updating the speed with latest version of detectron2/pytorch/etc., so they might be different from the metrics file. Training speed for multi-machine jobs is not provided.
Inference speed is measured by tools/train_net.py --eval-only, or inference_on_dataset(), with batch size 1 in detectron2 directly. Measuring it with custom code may introduce other overhead. Actual deployment in production should in general be faster than the given inference speed due to more optimizations.
The model id column is provided for ease of reference. To check downloaded file integrity, any model on this page contains its md5 prefix in its file name.
Training curves and other statistics can be found in metrics for each model.

Common Settings for COCO Models

All COCO models were trained on train2017 and evaluated on val2017.
The default settings are not directly comparable with Detectron's standard settings. For example, our default training data augmentation uses scale jittering in addition to horizontal flipping.

To make fair comparisons with Detectron's settings, see Detectron1-Comparisons for accuracy comparison, and benchmarks for speed comparison.
For Faster/Mask R-CNN, we provide baselines based on 3 different backbone combinations:
- FPN: Use a ResNet+FPN backbone with standard conv and FC heads for mask and box prediction, respectively. It obtains the best speed/accuracy tradeoff, but the other two are still useful for research.
- C4: Use a ResNet conv4 backbone with conv5 head. The original baseline in the Faster R-CNN paper.
- DC5 (Dilated-C5): Use a ResNet conv5 backbone with dilations in conv5, and standard conv and FC heads for mask and box prediction, respectively. This is used by the Deformable ConvNet paper.
Most models are trained with the 3x schedule (~37 COCO epochs). Although 1x models are heavily under-trained, we provide some ResNet-50 models with the 1x (~12 COCO epochs) training schedule for comparison when doing quick research iteration.

ImageNet Pretrained Models

It's common to initialize from backbone models pre-trained on ImageNet classification tasks. The following backbone models are available:

R-50.pkl: converted copy of MSRA's original ResNet-50 model.
R-101.pkl: converted copy of MSRA's original ResNet-101 model.
X-101-32x8d.pkl: ResNeXt-101-32x8d model trained with Caffe2 at FB.
R-50.pkl (torchvision): converted copy of torchvision's ResNet-50 model. More details can be found in the conversion script.

Note that the above models have different format from those provided in Detectron: we do not fuse BatchNorm into an affine layer. Pretrained models in Detectron's format can still be used. For example:

X-152-32x8d-IN5k.pkl: ResNeXt-152-32x8d model trained on ImageNet-5k with Caffe2 at FB (see ResNeXt paper for details on ImageNet-5k).
R-50-GN.pkl: ResNet-50 with Group Normalization.
R-101-GN.pkl: ResNet-101 with Group Normalization.

These models require slightly different settings regarding normalization and architecture. See the model zoo configs for reference.

New baselines using Large-Scale Jitter and Longer Training Schedule

The following baselines of COCO Instance Segmentation with Mask R-CNN are generated using a longer training schedule and large-scale jitter as described in Google's Simple Copy-Paste Data Augmentation paper. These models are trained from scratch using random initialization. These baselines exceed the previous Mask R-CNN baselines.

In the following table, one epoch consists of training on 118000 COCO images.

LVIS Instance Segmentation Baselines with Mask R-CNN

Mask R-CNN baselines on the LVIS dataset, v0.5. These baselines are described in Table 3(c) of the LVIS paper.

NOTE: the 1x schedule here has the same amount of iterations as the COCO 1x baselines. They are roughly 24 epochs of LVISv0.5 data. The final results of these configs have large variance across different runs.
