Facebook AI Research 开源了 Faster R-CNN 和 Mask R-CNN 的 PyTorch 1.0 实现基准:MaskRCNN-Benchmark。相比 Detectron 和 mmdetection,MaskRCNN-Benchmark 的性能相当,并拥有更快的训练速度和更低的 GPU 内存占用,众多亮点如下。

这篇文章主要是记录我使用訪框架训练自己的数据集的过程,总得来说还是比较容易上手的,当然坑也是有一点的。目前只包含了Mask R-CNN和Faster R-CNN两种检测模型,我尝试了一下Mask R-CNN(不包含语义分割)和Faster R-CNN目标检测的功能,也是因为我现在的工作只要用到目标检测。
我的基础环境:
系统:Ubutun 16.04
内核:4.15.0-36-generic
Python环境:Anaconda3
要求的环境:
$ conda create --name maskrcnn_benchmark
$ source activate maskrcnn_benchmark
# this installs the right pip and dependencies for the fresh python
$ conda install ipython
# maskrnn_benchmark and coco api dependencies
$ pip install ninja yacs cython matplotlib
# follow PyTorch installation in https://pytorch.org/get-started/locally/
# we give the instructions for CUDA 9.0
$ conda install pytorch-nightly -c pytorch
# install torchvision
$ cd ~/github
$ git clone https://github.com/pytorch/vision.git
$ cd vision
$ python setup.py install
# install pycocotools
$ cd ~/github
$ git clone https://github.com/cocodataset/cocoapi.git
$ cd cocoapi/PythonAPI
$ python setup.py build_ext install
# install PyTorch Detection
$ cd ~/github
$ git clone https://github.com/facebookresearch/maskrcnn-benchmark.git
$ cd maskrcnn-benchmark
$ python setup.py build develop
到这一步,maskrcnn-benchmark的安装就已经完成了,下一步是要准备训练/验证数据。
maskrcnn-benchmark默认是为coco数据集量身打造的,简单起见我跑自己的数据集也完全照搬的coco的设置。COCO数据集现在有3种标注类型:object instances(目标实例), object keypoints(目标上的关键点), 和image captions(看图说话),使用JSON文件存储。具体可以参考COCO数据集的标注格式一文。我的实验只需要用到object detection,甚至都不需要语义分割,格式相对简单。
{
"info": {..} #描述这个数据集的整体信息,训练自己的数据直接给个空词典ok
"licenses": [license],#可以包含多个licenses实例,训练自己的数据继续给个空列表ok
"images": [
{
'file_name': 'xx', #文件路径,这个路径将和一个将root的根目录拼接成你的文件访问路径
'height': xx, #图片高度
'width': xx, #图片宽度
'id': xx,#每张图片都有一个唯一的id,从0开始编码即可
},
...
],
"annotations": [
{
'segmentation': [] #语义分割的时候要用到,我只用到了目标检测,所以忽略.
'area': xx, #区域面积,宽*高就是区域面积
'image_id': xx, #一张当然可能有多个标注,这个image_id和images中的id相对应
'bbox':[x,y,w,h], #通过这4个坐标来定位边框
'category_id': xx, #类别id(与categories中的id对应)
'id': xx, #这是这个annotation的id,也是唯一的,从0编号即可
},
...
]
"categories": [
{
'supercategory': xx, #你类别名称,例如vehicle(交通工具),下一级有car,truck等.
我自己的数据集没有这种层次关系,我就随便取了个名字adas
'id': xx, #类别的id,从1开始编号,0默认为背景
'name': xx, #这个子类别的名字
},
...
],
}
参照上面的标注格式分别生成训练集和验证集的json标注文件,可以继续沿用coco数据集默认的名字:instances_train2104.json和instances_val2014.json。数据集的目录组织结构可以参考下面的整体目录结构中datasets目录。

这样一来数据集就准备好了。
这里涉及到的配置文件主要有3个:
模型配置文件在启动训练时由--config-file参数指定,在config子目录下默认提供了mask_rcnn和faster_rcnn框架不同骨干网的基于YAML格式的配置文件。我选用的是e2e_mask_rcnn_R_101_FPN_1x.yaml,也就是使用mask_rcnn检测模型,骨干网使用ResNet101-FPN,配置详情如下(根据自己的数据集作相应的调整):
MODEL:
META_ARCHITECTURE: "GeneralizedRCNN"
WEIGHT: "catalog://ImageNetPretrained/MSRA/R-101"
BACKBONE:
CONV_BODY: "R-101-FPN"
OUT_CHANNELS: 256
RPN:
USE_FPN: True #是否使用FPN,也就是特征金字塔结构,选择True将在不同的特征图提取候选区域
ANCHOR_STRIDE: (4, 8, 16, 32, 64) #ANCHOR的步长
PRE_NMS_TOP_N_TRAIN: 2000 #训练时,NMS之前的候选区数量
PRE_NMS_TOP_N_TEST: 1000 #测试时,NMS之后的候选区数量
POST_NMS_TOP_N_TEST: 1000
FPN_POST_NMS_TOP_N_TEST: 1000
ROI_HEADS:
USE_FPN: True
ROI_BOX_HEAD:
POOLER_RESOLUTION: 7
POOLER_SCALES: (0.25, 0.125, 0.0625, 0.03125)
POOLER_SAMPLING_RATIO: 2
FEATURE_EXTRACTOR: "FPN2MLPFeatureExtractor"
PREDICTOR: "FPNPredictor"
ROI_MASK_HEAD:
POOLER_SCALES: (0.25, 0.125, 0.0625, 0.03125)
FEATURE_EXTRACTOR: "MaskRCNNFPNFeatureExtractor"
PREDICTOR: "MaskRCNNC4Predictor"
POOLER_RESOLUTION: 14
POOLER_SAMPLING_RATIO: 2
RESOLUTION: 28
SHARE_BOX_FEATURE_EXTRACTOR: False
MASK_ON: False #默认是True,我这里改为False,因为我没有用到语义分割的功能
DATASETS:
TRAIN: ("coco_2014_train",) #注意这里的训练集和测试集的名字,
TEST: ("coco_2014_val",) #它们和paths_catalog.py中DATASETS相对应
DATALOADER:
SIZE_DIVISIBILITY: 32
SOLVER:
BASE_LR: 0.01 #起始学习率,学习率的调整有多种策略,訪框架自定义了一种策略
WEIGHT_DECAY: 0.0001
#这是什么意思呢?是为了在不同的迭代区间进行学习率的调整而设定的.以我的数据集为例,
#我149898张图,计划是每4个epoch衰减一次,所以如下设置.
STEPS: (599592, 1199184)
MAX_ITER: 1300000 #最大迭代次数
看完模型配置文件,你再看看MaskRCNN-Benchmark框架默认配置文件(defaults.py)你就会发现有不少参数有重合。嘿嘿,阅读代码会发现defaults.py会合并模型配置文件中的参数,defaults.py顾名思义就是提供了默认的参数配置,如果模型配置文件中对訪参数有改动则以模型中的为准。当然还有更多的参数是模型配置文件中没有的,我这里对部分参数进行简单的说明。

注意观察发现,在预热阶段,也就是前500次迭代内,虽然我初始学习率是设置的0.1,但是因为预热策略的原因,学习率调整为0.003333,而500次之后学习率恢复到0.01。训练的平均损失(200次迭代内的平均损失)由开始的0.3616降到0.0849。当然到此训练还没有完结,我跑一次验证看一下效果。
