# Benchmarks
Here we benchmark the training speed of a Mask R-CNN in detectron2,
with some other popular open source Mask R-CNN implementations.
### Settings
* Hardware: 8 NVIDIA V100s with NVLink.
* Software: Python 3.7, CUDA 10.1, cuDNN 7.6.5, PyTorch 1.5,
TensorFlow 1.15.0rc2, Keras 2.2.5, MxNet 1.6.0b20190820.
* Model: an end-to-end R-50-FPN Mask-RCNN model, using the same hyperparameter as the
[Detectron baseline config](https://github.com/facebookresearch/Detectron/blob/master/configs/12_2017_baselines/e2e_mask_rcnn_R-50-FPN_1x.yaml)
(it does no have scale augmentation).
* Metrics: We use the average throughput in iterations 100-500 to skip GPU warmup time.
Note that for R-CNN-style models, the throughput of a model typically changes during training, because
it depends on the predictions of the model. Therefore this metric is not directly comparable with
"train speed" in model zoo, which is the average speed of the entire training run.
### Main Results

```
Details for each implementation:
* __Detectron2__: with release v0.1.2, run:
```
python tools/train_net.py --config-file configs/Detectron1-Comparisons/mask_rcnn_R_50_FPN_noaug_1x.yaml --num-gpus 8
```
* __mmdetection__: at commit `b0d845f`, run
```
./tools/dist_train.sh configs/mask_rcnn/mask_rcnn_r50_caffe_fpn_1x_coco.py 8
```
* __maskrcnn-benchmark__: use commit `0ce8f6f` with `sed -i ‘s/torch.uint8/torch.bool/g’ **/*.py; sed -i 's/AT_CHECK/TORCH_CHECK/g' **/*.cu`
to make it compatible with PyTorch 1.5. Then, run training with
```
python -m torch.distributed.launch --nproc_per_node=8 tools/train_net.py --config-file configs/e2e_mask_rcnn_R_50_FPN_1x.yaml
```
The speed we observed is faster than its model zoo, likely due to different software versions.
* __tensorpack__: at commit `caafda`, `export TF_CUDNN_USE_AUTOTUNE=0`, then run
```
mpirun -np 8 ./train.py --config DATA.BASEDIR=/data/coco TRAINER=horovod BACKBONE.STRIDE_1X1=True TRAIN.STEPS_PER_EPOCH=50 --load ImageNet-R50-AlignPadding.npz
```
* __SimpleDet__: at commit `9187a1`, run
```
python detection_train.py --config config/mask_r50v1_fpn_1x.py
```
* __Detectron__: run
```
python tools/train_net.py --cfg configs/12_2017_baselines/e2e_mask_rcnn_R-50-FPN_1x.yaml
```
Note that many of its ops run on CPUs, therefore the performance is limited.
* __matterport/Mask_RCNN__: at commit `3deaec`, apply the following diff, `export TF_CUDNN_USE_AUTOTUNE=0`, then run
```
python coco.py train --dataset=/data/coco/ --model=imagenet
```
Note that many small details in this implementation might be different
from Detectron's standards.
