小白第一次写系统文，技术不佳，主要是为了自己后期查找方便，望各路大神不喜轻喷~~
文末有7个主要文件的完整版本，喜欢请查阅~
0 重要文件结构梳理
主要文件结构如下图所示。为了方便后续文件位置对照，先把总图摆在这了。纯原创哈~~
1 前期安装和环境配置
1.1 下载安装
参考：https://pjreddie.com/darknet/yolo/
git clone https://github.com/pjreddie/darknet
cd darknet
make
下载预训练模型darknet53.conv.74，放置路径建议：darknet/weights/darknet53.conv.74。
1.2 修改Makefile
修改darknet文件夹中的Makefile文件的指定内容：
修改前：
GPU=0
CUDNN=0
OPENCV=0
NVCC=nvcc //根据自己的版本修改
COMMON+=-DGPU -I/usr/local/cuda/include/
LDFLAGS+=-L/usr/local/cuda/lib64 -lcuda -lcudart -lcublas -lcurand
修改后：
GPU=1
CUDNN=1
OPENCV=1
NVCC=/usr/local/cuda-10.1/bin/nvcc //根据自己的版本修改
COMMON+=-DGPU -I/usr/local/cuda-10.1/include/
LDFLAGS+=-L/usr/local/cuda-10.1/lib64 -L/usr/lib/nvidia -lcuda -lcudart -lcublas -lcurand
完整的Makefile文件见附录①。修改Makefile后，需要重新编译：
make clean
make
1.3 准备数据集VOC2007
1.3.1 初步形成VOC2007文件夹
使用LabelImg软件进行图片标注，将原始图片和相应xml标注文件放入VOC2007文件夹。
VOC2007文件夹中包含3个子文件夹，分别是：Annotations、ImageSets、JPEGImages。为了避免不必要的麻烦，这三个名字一个字母都不要错哦。
其中，Annotations文件夹用于存放所有的xml文件，把你的xml文件都放这里；JPEGImages用于存放所有的图片，把你的jpg文件都放这里；而ImageSets文件夹类似一个管理员的感觉，其中只有一个Main文件夹，Main文件夹里面暂时是空的，但是要有这个文件夹。
1.3.2 划分数据集：xml2txt.py
#_*_coding:utf-8
import os
import random
# 0.9,0.9能够保证此时的train:val:test = 8:1:1
xmlfilepath="./Annotations" # xml文件路径
txtsavepath="./ImageSets/Main" # txt文件保存路径
trainval_percent=0.9 # trainval集占整个数据集的百分比,剩下的就是test集所占的百分比
train_percent=0.9 # train集占trainval集的百分比,剩下的就是val集所占的百分比
def xml_to_txt():
xmllist=os.listdir(xmlfilepath) # 导入xml文件列表
xml_num=len(xmllist) # xml文件数量
num_list=range(xml_num) # 将xml文件分别用数字表示，从0到xml_num(不包含xml_num)
trainval_num=int(xml_num*trainval_percent) # trainval集样本数量
trainval=random.sample(num_list,trainval_num) #从num_list个xml文件中随机选取trainval_num个当作trainval数据集
train_num=int(trainval_num*train_percent) # train集样本数量
train=random.sample(trainval,train_num) # 从trainval集中随机选取train_num个当作train数据集
ftrainval=open(txtsavepath+'/trainval.txt','w')
ftest=open(txtsavepath+'/test.txt','w')
ftrain=open(txtsavepath+'/train.txt','w')
fval=open(txtsavepath+'/val.txt','w')
for i in num_list:
name=xmllist[i][:-4]+'
'
if i in trainval:
ftrainval.write(name)
if i in train:
ftrain.write(name)
else:
fval.write(name)
else:
ftest.write(name)
ftrainval.close()
ftrain.close()
fval.close()
ftest.close()
xml_to_txt() # 调用转换函数
将xml2txt.py文件放到VOC2007文件夹中，在VOC2007文件夹下运行：
python xml2txt.py //用的是python3
运行后，VOC2007/Main文件夹中多出4个文本文件：test.txt、train.txt、trainval.txt、val.txt。4个txt文件里面存放的都是一行行干净整齐的文件名（不含路径和后缀），表示哪些样本用于train，而哪些用于test等。这个是通过scripts下的voc_label.py文件生成的。
000001
以上提到的文件夹，缺啥补啥，至此，一个独立的数据集已经建立完成，但还不是能使用的，要想使用，还得做两件事：
①把VOC2007数据集纳入darknet体系；
②修改并运行voc_label.py脚本。
1.3.3 把VOC2007数据集纳入darknet体系
在darknet/scripts文件夹下新建VOCdevkit文件夹（一个字母都不能错），把VOC2007文件夹直接放入，最后层级关系是：darknet/scripts/VOCdevkit/VOC2007
1.3.4 修改并运行voc_label.py脚本
修改scripts下的voc_label.py文件：
修改前：
sets=[('2012', 'train'), ('2012', 'val'), ('2007', 'train'), ('2007', 'val'), ('2007', 'test')]
classes = ["aeroplane", "bicycle", "bird", "boat", "bottle", "bus", "car", "cat", "chair", "cow", "diningtable", "dog", "horse", "motorbike", "person", "pottedplant", "sheep", "sofa", "train", "tvmonitor"]
os.system("cat 2007_train.txt 2007_val.txt > train.txt")
os.system("cat 2007_train.txt 2007_val.txt 2007_test.txt 2007_trainval.txt> train.all.txt")
修改后：
sets = [('2007', 'train'), ('2007', 'trainval'), ('2007', 'test'), ('2007', 'val')]
classes = ["excreting","notexcreting","likeboarurination","0","1","2","3","4","5","6","7","8","f","h","x","sickfeces"] //换成自己的类别
#os.system("cat 2007_train.txt 2007_val.txt > train.txt")
#os.system("cat 2007_train.txt 2007_val.txt 2007_test.txt 2007_trainval.txt> train.all.txt")
在scripts下运行：
python voc_label.py //用的python3
运行后，视觉上有两个变化：
① darkent/scripts文件夹中出现4个文本文件：2007_test.txt、2007_train.txt、2007_trainval.txt、2007_val.txt。里面存放的是图片的完整路径和带后缀的文件名：
/home/dj/dingjing/darknet/scripts/VOCdevkit/VOC2007/JPEGImages/000001.jpg
② VOC2007文件夹中出现labels文件夹，里面放的是所有xml转换成的txt，每个txt文件中内容类似下面：
| 类别编号 | xmin | xmax | ymin | ymax |
|---|---|---|---|---|
| 1 | 0.5037109375000001 | 0.290625 | 0.20039062500000002 | 0.13125 |
| 1 | 0.3853515625 | 0.43506944444444445 | 0.103515625 | 0.38263888 |
| 11 | 0.5326171875 | 0.2611111111111111 | 0.053515625 | 0.051388888 |
| 3 | 0.3615234375 | 0.38159722222222225 | 0.033984375 | 0.054861 |
第1列数字是类别编号，第2列至第5列是标注框的相对坐标。相对坐标 = 绝对坐标/图片长宽。
1.4 修改配置文件
共3部分：修改cfg中两个文件voc.data和yolov3-voc.cfg,修改data下的类别名称文件xxx.names。
1.4.1 修改cfg中voc.data
修改前：
classes= 20
train = /home/pjreddie/data/voc/train.txt
valid = /home/pjreddie/data/voc/2007_test.txt
names = data/voc.names
backup = backup
修改后：
classes= 16
train = /home/dj/dingjing/darknet/scripts/2007_train.txt
valid = /home/dj/dingjing/darknet/scripts/2007_test.txt
names = data/dingall.names
backup = backup
1.4.2 修改cfg中yolov3-voc.cfg
修改前：

max_batches = 50200

classes=20

num=9
jitter=.3
ignore_thresh = .5

修改后完整版的yolov3-voc.cfg见附录⑦。
1.4.3 修改data下的类别名称文件xxx.names

2 训练
2.1 单GPU训练
./darknet detector train cfg/voc.data cfg/yolov3-voc.cfg weights/darknet53.conv.74 | tee dingall.txt
tee是为了生成训练过程记录文本，便于后续模型分析。
2.2 多GPU训练
./darknet detector train cfg/voc.data cfg/yolov3-voc.cfg weights/darknet53.conv.74 -gpus 0,1,2,3
2.3 从checkpoint断点开始训练
./darknet detector train cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc.backup -gpus 0,1,2,3
3 模型测试
3.1 修改yolov3-voc.cfg
cfg中yolov3-voc.cfg中，关闭训练开关，打开测试开关：
修改前：
[net]
# Testing
# batch=1
# subdivisions=1
# Training
batch=64
subdivisions=16
修改后：
[net]
# Testing
batch=1
subdivisions=1
# Training
# batch=64
# subdivisions=16
3.2 测试单张图片
./darknet detector test cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc_final.weights data/xxx.jpg
3.3 批量测试（test数据集）
① 在detector.c中修改生成文件的名称为comp4_det_test
首先修改examples/detector.c:validate_detector函数中，约为424行，将comp4_det_val改成comp4_det_test，如果已经是就不需修改啦，然后在darknet文件夹下重新编译：
make clean
make
② 批量测试——输出文本检测结果(first)(输出在results文件夹中comp4_det_test_类名.txt）
./darknet detector valid cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc_final.weights
③ 批量测试——输出图片检测结果(second)（输出在data/out-img文件夹中）
./darknet detector test cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc_final.weights
Enter Image Path: scripts/2007_test.txt
④ 计算recall（执行这个命令需要修改detector.c文件，修改信息请参考“detector.c修改”）
./darknet detector recall cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc_final.weights
⑤（切换成python3）计算各类别的AP和mAP:生成plk文件用于画PR曲线
执行下列命令前一定要注意把darknet/scripts/VOCdevkit/annotations_cache这个文件夹屏蔽掉，否则影响新的文件输出（参考https://blog.csdn.net/weixin_41143397/article/details/83831839
）
python reval_voc.py --voc_dir /home/dj/dingjing/darknet/scripts/VOCdevkit --year 2007 --image_set test --classes /home/dj/dingjing/darknet/data/dingall.names x(x是自己新建的文件夹名称，用来保存最后生成的.txt文件)
3.5 测试视频
./darknet detector demo cfg/voc.data cfg/yolov3-voc.cfg backup/yolov3-voc_25000.weights data/1.mp4
4 训练过程分析
4.1 绘制loss-iter曲线
新建文件夹keshihua，将tee生成的dingall.txt放进来，将iouLoss.py文件放进来。
其中，iouLoss.py内容如下，需要修改的地方：g_log_path = "dingall.txt"。

| 关键字 | 含义 |
|---|---|
| Region | cfg文件中yolo-layer的索引 |
| Avg IOU | 当前迭代中，预测的box与标注的box的平均交并比，越大越好，期望数值为1 |
| Class | 标注物体的分类准确率，越大越好，期望数值为1 |
| obj | 越大越好，期望数值为1 |
| No obj | 越小越好，但不为零 |
| .5R | 以IOU=0.5为阈值时候的recall; recall = 检出的正样本/实际的正样本 |
| .75R | 以IOU=0.75为阈值时候的recall |

以上输出显示了所有训练图片的一个批次（batch），批次大小的划分根据我们在 .cfg 文件中设置的subdivisions参数。
在我使用的 .cfg 文件中 batch = 64 ，subdivision = 16，所以在训练输出中，训练迭代包含了16组，每组又包含了4张图片，跟设定的batch和subdivision的值一致。
但是此处有16*3条信息，每组包含三条信息，分别是：Region 82、Region 94、Region 106。
三个尺度上预测不同大小的框：
- 82卷积层 为最大的预测尺度，使用较大的mask，但是可以预测出较小的物体；
- 94卷积层 为中间的预测尺度，使用中等的mask；
- 106卷积层为最小的预测尺度，使用较小的mask，可以预测出较大的物体
每个batch都会有这样一个输出：
2706: 1.350835, 1.386559 avg, 0.001000 rate, 3.323842 seconds, 173184 images
batch 总损失 平均损失 学习率 花费时间 参与训练的图片总数
