Scaled YOLOv4 训练自己的数据集

感谢 https://github.com/WongKinYiu/ScaledYOLOv4 大佬的开源！！！

DataXujing

我们以训练YOLOv4-P7为例，介绍如何基于Scaled YOLOv4训练自己的数据集

0.环境配置

python3.7 cuda 10.2
pytorch==1.6.0
torchvision==0.7.0

# mish-cuda
# 使用预训练的模型
git clone https://github.com/thomasbrandon/mish-cuda mc
cd mc

# change all of name which is mish_cuda to mish_mish and build.
# 1. mc/src/mish_cuda -> mc/src/mish_mish
# 2. mc/csrc/mish_cuda.cpp -> mc/csrc/mish_mish.cpp
# 3. in mc/setup.py
#   3.1 line 5 -> 'csrc/mish_mish.cpp'
#   3.2 line 11 -> name='mish_mish'
#   3.3 line 20 -> 'mish_mish._C'

python setup.py build
# rename mc/build/lib.xxx folder to mc/build/lib

# modify import in models/common.py
# line 7 -> from mc.build.lib.mish_mish import MishCuda as Mish
# 不使用预训练的模型，可以
git clone https://github.com/thomasbrandon/mish-cuda
cd mish-cuda
python setup.py build install

遗憾的是我再CUDA9.0下成功的安装了mish-cuda,但是在CUDA9.2,CUDA10.0和CUDA10.2下均未成功安装mish-cuda,最后我在common.py中基于pytorch实现了Mish,实现方式如下：

 no pretrain
# from mish_cuda import MishCuda as Mish
# pretrain
#from mc.build.lib.mish_mish import MishCuda as Mish

#------------------by xujing------------
# 实在装不上mish-cuda,用pytorch自己实现
class Mish(nn.Module):
    def __init__(self):
        super().__init__()
        # print("Mish activation loaded...")
    def forward(self,x):
        x = x * (torch.tanh(F.softplus(x)))
        return x
# ---------------------------------------------

1.数据集准备

数据集的准备请参考：https://github.com/DataXujing/YOLO-v5,其结构如下图所示：

eus         # 数据集名称
├─images
│  ├─train  # 训练图片存放地址
│  └─val    # 验证图片存放地址
└─labels
    ├─train # train txt标注文件存放地址
    └─val   # val txt标注文件存放地址

2.模型修改

  • 修改增加./data/eus.yaml
# train and val datasets (image directory or *.txt file with image paths)
train: ./eus/images/train  # <-----------训练集存放地址
val: ./eus/images/val  # <----------开发集存放地址
test: ./eus/images/val  # <--------测试集存放地址

# number of classes
nc: 7     # <----------类别数量

# class names
names: ["Liomyoma", "Lipoma", "Pancreatic Rest", "GIST", "Cyst",  "NET", "Cancer"]   # <----列别列表
  • 修改增加./models/eus/yolov4-p7.yaml
# parameters
nc: 7  # <----------------------------------number of classes
depth_multiple: 1.0  # expand model depth
width_multiple: 1.25  # expand layer channels

# anchors
anchors:
  - [13,17,  22,25,  27,66,  55,41]  # P3/8

   [[36,40,44,48,52], 1, Detect, [nc, anchors]],   # Detect(P3, P4, P5, P6, P7)
  ]

3.模型训练

# {YOLOv4-P5, YOLOv4-P6, YOLOv4-P7} use input resolution {896, 1280, 1536} for training respectively.
# 我在V100上训练，但是对于P7而言，在896的分辨率下，batch size=4才可以正常训练

python37 -m torch.distributed.launch --nproc_per_node 4 train.py --batch-size 64 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights 'pretrain/yolov4-p7.pt' --sync-bn --device 0 --name yolov4-p7

python37 -m torch.distributed.launch --nproc_per_node 4 train.py --batch-size 64 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --sync-bn --device 0 --name yolov4-p7


python train.py --batch-size 64 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights 'pretrain/yolov4-p7.pt' --sync-bn --device 0 --name yolov4-p7

python --nproc_per_node 4 train.py --batch-size 64 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights 'pretrain/yolov4-p7.pt' --sync-bn --device 0 --name yolov4-p7
python train.py --batch-size 64 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights '' --sync-bn --device 0 --name yolov4-p7

# V100下的训练
python train.py --batch-size 4 --img 896 896 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights '' --sync-bn --device 0 --name yolov4-p7

python train.py --batch-size 8 --img 640 640 --data eus.yaml --cfg models/eus/yolov4-p7.yaml --weights '' --sync-bn --device 0 --name yolov4-p7

训练数据

测试数据

4.模型推断

  • 模型测试
# download {yolov4-p5.pt, yolov4-p6.pt, yolov4-p7.pt} and put them in /yolo/weights/ folder.
python test.py --img 896 --conf 0.001 --batch 8 --device 0 --data eus.yaml --weights weights/yolov4-p5.pt
python test.py --img 1280 --conf 0.001 --batch 8 --device 0 --data eus.yaml --weights weights/yolov4-p6.pt
python test.py --img 1536 --conf 0.001 --batch 8 --device 0 --data coco.yaml --weights weights/yolov4-p7.pt
  • 模型推断

图像识别：

python test_img.py

视频识别：

python test_video.py

5.DEMO

6.TensorRT加速

  • 1.编译安装opencv
# download: https://github.com/opencv/opencv/archive/4.3.0.zip

# Install dependence
sudo apt-get install cmake git libgtk2.0-dev pkg-config  libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install libtbb2  libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
sudo apt-get install qtbase5-dev qtdeclarative5-dev
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt-get update
sudo apt install libjasper1 libjasper-dev 

# make
mkdir build && cd build
cmake .. -DWITH_QT=ON -DBUILD_TIFF=ON -DOPENCV_GENERATE_PKGCONFIG=ON -DCMAKE_INSTALL_PREFIX=/usr/local
sudo make -j16
sudo make install

# config
pkg-config --cflags opencv4
sudo gedit /etc/ld.so.conf.d/opencv.conf

and input

/usr/local/lib

如果报错，可参考：https://blog.csdn.net/darren2015zdc/article/details/74011918
  • 2.编译安装yaml-cpp 0.6.3
download: https://github.com/jbeder/yaml-cpp/archive/yaml-cpp-0.6.3.zip

mkdir build && cd build
cmake ..
make -j
  • 3.修改CMakeLists.txt

修改TensorRT下的CMakeLists.txt文件夹

cmake_minimum_required(VERSION 3.5)

project(ScaledYOLOv4_trt)

set(CMAKE_CXX_STANDARD 14)

# CUDA
find_package(CUDA REQUIRED)
message(STATUS "Find CUDA include at ${CUDA_INCLUDE_DIRS}")
message(STATUS "Find CUDA libraries: ${CUDA_LIBRARIES}")

# TensorRT
set(TENSORRT_ROOT /home/myuser/xujing/TensorRT-7.0.0.11)   
find_path(TENSORRT_INCLUDE_DIR NvInfer.h
        HINTS ${TENSORRT_ROOT} PATH_SUFFIXES include/)
message(STATUS "Found TensorRT headers at ${TENSORRT_INCLUDE_DIR}")
find_library(TENSORRT_LIBRARY_INFER nvinfer
        HINTS ${TENSORRT_ROOT} ${TENSORRT_BUILD} ${CUDA_TOOLKIT_ROOT_DIR}
        PATH_SUFFIXES lib lib64 lib/x64)
find_library(TENSORRT_LIBRARY_ONNXPARSER nvonnxparser
        HINTS  ${TENSORRT_ROOT} ${TENSORRT_BUILD} ${CUDA_TOOLKIT_ROOT_DIR}
        PATH_SUFFIXES lib lib64 lib/x64)
set(TENSORRT_LIBRARY ${TENSORRT_LIBRARY_INFER} ${TENSORRT_LIBRARY_ONNXPARSER})
message(STATUS "Find TensorRT libs: ${TENSORRT_LIBRARY}")

# OpenCV
find_package(OpenCV REQUIRED)
message(STATUS "Find OpenCV include at ${OpenCV_INCLUDE_DIRS}")
message(STATUS "Find OpenCV libraries: ${OpenCV_LIBRARIES}")

set(COMMON_INCLUDE ./includes/common)   
set(YAML_INCLUDE ./includes/yaml-cpp/include)
set(YAML_LIB_DIR ./includes/yaml-cpp/libs)

include_directories(${CUDA_INCLUDE_DIRS} ${TENSORRT_INCLUDE_DIR} /home/myuser/xujing/tensorRT_apply/opencv-4.3.0 ${COMMON_INCLUDE} ${YAML_INCLUDE})
link_directories(${YAML_LIB_DIR})

add_executable(ScaledYOLOv4_trt main.cpp ScaledYOLOv4.cpp)
target_link_libraries(ScaledYOLOv4_trt ${OpenCV_LIBRARIES} ${CUDA_LIBRARIES} ${TENSORRT_LIBRARY} yaml-cpp)
  • 4.修改运行export_onnx.py
# 将TensorRT文件加下的export_onnx.py复制到项目根目录
# 修改模型路径和input图像大小

python export_onnx.py
  • 5.编译ScaledYOLOv4
mkdir build && cd build
cmake ..
make -j

如果报错很可能是安装环境稳定或CMakeLists.txt链接库的路径问题，请自行检查解决。

编译成功后：

使用yolov4-p7做模型推断：

# 将onnx模型存放到config-p7.yaml指定的文件夹下

./ScaledYOLOv4_trt ../config-p7.yaml ../samples/
