js… 全流程训练语义分割数据集 数据标注json转mask 运行源码MMSegmentation模型选择运行部分 数据标注
# 安装
pip install labelme
# 启动labelme
labelme然后 ctrl N 开启多边形标注即可命名类为person 之后会保存到同目录下json文件
json转mask
下载labelme代码里的转换代码 labels里存储的如下形式 运行指令
python labelme2voc.py ./img output labels.txt生成如下
运行源码MMSegmentation
mmseg/datasets里生成一个my_data.py文件这个文件存储的是类别信息和seg颜色 需要多加一个backbone

from mmseg.registry import DATASETS
from .basesegdataset import BaseSegDatasetDATASETS.register_module()
class mydata(BaseSegDataset):Cityscapes dataset.The img_suffix is fixed to _leftImg8bit.png and seg_map_suffix isfixed to _gtFine_labelTrainIds.png for Cityscapes dataset.METAINFO dict(classes(backbone,person),palette[[128, 64, 128], [244, 35, 232]])def __init__(self,img_suffix.jpg,seg_map_suffix.png,reduce_zero_labelTrue,**kwargs) - None:super().__init__(img_suffiximg_suffix,seg_map_suffixseg_map_suffix,reduce_zero_labelreduce_zero_label,**kwargs)mmseg/utils/class_names.py文件里添加不加backbone也不报错这里没加最好加上另外seg颜色要与上面文件一致
def mydata_classes():shengteng class names for external use.return [person]def mydata_palette():return [[244, 35, 232]]mmseg/datasets/init.py中加引入
from .my_data import mydataconfigs/base/datasets文件下新建一个my_data.py文件 这个就是一个读取数据的文件了包含数据地址、type和加载增加等方式

test_evaluator val_evaluator模型选择运行部分
我选择的是configs/deeplabv3/deeplabv3_r50-d8_4xb2-40k_cityscapes-512x1024.py主要是修改继承的数据部分
运行 每次修改配置文件最好是运行一遍python setup.py install
python setup.py install
python ./tools/train.py ./configs/deeplabv3/deeplabv3_r50-d8_4xb2-40k_cityscapes-512x1024.py
