openpose-GPU版本从安装到实战全攻略！(win10)

前言
必须按照版本执行的：

GPU： 3060

CUDA：10.2

cuDNN：7.6.53

win10

openpose 1.7 V

cmake: 3.15.5

VS2019

python 3.7

如果你使用的cuda版本为11，请务必降级为10.2

10.0也不行，已经试过了，必须10.2

cuDNN也必须是对应版本。

太痛了！！！！！！！！

上述原因主要是openpose不支持cuDNN 8版本，并且每个cuDNN对应的cuda也是固定的，因此我选择降版本来解决这个问题。

一、基本配置
1、github上下载openpose后，解压到自己的目录下，建议不要解压到含有中文路径的地方

2、首先下载所需文件，打开到openpose-master\3rdparty\windows 下，可以看到五个bat文件

双击后自动下载，或网盘：
caffe等依赖包解压到以下目录\openpose-master\3rdparty\windows

链接：https://pan.baidu.com/s/1sikP3ppFVp14qQzMZn-IQA

提取码：y1i1

pybind11解压到以下目录\openpose-master\3rdparty

链接：https://pan.baidu.com/s/1682rKdIyl22J02HuH-0I6Q

提取码：fb6t

model解压到以下目录\openpose-master\models

链接：https://pan.baidu.com/s/1rXiYqXc7oAUhQwpjX9oXwg

提取码：jgb5
将所有下载的压缩包解压到此目录下

此时所需文件下载完成。
二、CMAKE安装
CMake 官方下载网址： https://cmake.org/download/
或网盘链接：https://pan.baidu.com/s/1G9ShmPPMSKgM10ONDmDXnA
提取码：z1up
解压到自定义文件即可
二、CMAKE配置
1、打开CMAKE-gui


选择自己的路径，如上图所示
2、如果后续想要使用python运行并修改程序，请务必进行以下操作

点击 Add Entry

选择到对应环境的pythonw.exe下就ok了。

3、然后进行configure一次

会出现一片红

选择BUILD_PYTHON （非必须，如果你要用python就选）

选择以下五个模型（必选）

继续选择

注意以下这里，虽然默认打勾，也要记得千万别取消这个钩，不然我们的cuDNN就白下了。（否则会暂用显存）

4、然后再次点击configure

debug直到configure done

然后点击generate，出现generate done即可
三、python运行
然后我们进行python调试

1、打开\openpose-master\build\examples\tutorial_api_python

可以选择pycharm or cmd运行，本文选择pycharm。

2、安装好虚拟环境，直接运行任意01-09的一个py文件。

3、大概率会出现以下报错

```Error: OpenPose library could not be found. Did you enable BUILD_PYTHON in CMake and have this Python script in the right folder?

解决方法
把build/bin里面的全部dll，复制到/build/python/openpose/Release

基本就不会出现这个错了。（还有的话就自行百度吧，只有这个bug我不确定咋解决）
运行基本可以直接成功了。

四、修改python代码读取自己的视频
读取自己的视频呢，参考我修改的以下代码。直接覆盖他自带的其中一个py文件就行

```python
# From Python
# It requires OpenCV installed for Python
import sys
import cv2
import os
from sys import platform
import argparse

try:
    # Import Openpose (Windows/Ubuntu/OSX)
    dir_path = os.path.dirname(os.path.realpath(__file__))
    try:
        # Windows Import
        if platform == "win32":
            # Change these variables to point to the correct folder (Release/x64 etc.)
            sys.path.append(dir_path + '/../../python/openpose/Release');
            os.environ['PATH'] = os.environ['PATH'] + ';' + dir_path + '/../../x64/Release;' + dir_path + '/../../bin;'
            import pyopenpose as op
        else:
            # Change these variables to point to the correct folder (Release/x64 etc.)
            sys.path.append('../../python');
            # If you run `make install` (default path is `/usr/local/python` for Ubuntu), you can also access the OpenPose/python module from there. This will install OpenPose and the python library at your desired installation path. Ensure that this is in your python path in order to use it.
            # sys.path.append('/usr/local/python')
            from openpose import pyopenpose as op
    except ImportError as e:
        print(
            'Error: OpenPose library could not be found. Did you enable `BUILD_PYTHON` in CMake and have this Python script in the right folder?')
        raise e

    # # Flags
    # parser = argparse.ArgumentParser()
    # parser.add_argument("--image_path", default="../../../examples/media/COCO_val2014_000000000192.jpg", help="Process an image. Read all standard formats (jpg, png, bmp, etc.).")
    # args = parser.parse_known_args()

    # Custom Params (refer to include/openpose/flags.hpp for more parameters)
    params = dict()
    params["model_folder"] = "../../../models/"
    params["hand"] = False
    params["number_people_max"] = 1
    params["disable_blending"] = True  # for black background
    # params["display"] = 0

    # # Add others in path?
    # for i in range(0, len(args[1])):
    #     curr_item = args[1][i]
    #     if i != len(args[1]) - 1:
    #         next_item = args[1][i + 1]
    #     else:
    #         next_item = "1"
    #     if "--" in curr_item and "--" in next_item:
    #         key = curr_item.replace('-', '')
    #         if key not in params:  params[key] = "1"
    #     elif "--" in curr_item and "--" not in next_item:
    #         key = curr_item.replace('-', '')
    #         if key not in params: params[key] = next_item

    # Construct it from system arguments
    # op.init_argv(args[1])
    # oppython = op.OpenposePython()

    # Starting OpenPose
    opWrapper = op.WrapperPython()
    opWrapper.configure(params)
    opWrapper.start()

    # Process Image
    datum = op.Datum()
    cap = cv2.VideoCapture("D:\Desktop\Videos/4.mp4") #输入视频
    output_dir = 'D:/Desktop/output/' + '4' + '/' #将处理结果以图片形式保存到指定文件夹

    fps = cap.get(cv2.CAP_PROP_FPS)
    size = (int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)), int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)))
    framecount = cap.get(cv2.CAP_PROP_FRAME_COUNT)
    print('Total frames in this video: ' + str(framecount))
    #videoWriter = cv2.VideoWriter("op720_2.avi", cv2.VideoWriter_fourcc('D', 'I', 'V', 'X'), fps, size)

    c = 0
    while cap.isOpened():
        hasFrame, frame = cap.read()
        if hasFrame:
            #img_resize = cv2.resize(frame, (640, 360))

            datum.cvInputData = img_resize
            opWrapper.emplaceAndPop(op.VectorDatum([datum]))
            opframe = datum.cvOutputData
            cv2.imshow("main", opframe)
            img = cv2.imwrite(output_dir + str(c) + '.jpg', opframe)

            c = c+1
            #videoWriter.write(opframe)
            if cv2.waitKey(1) & 0xFF == ord('q'):
                break
        else:
            break
    cap.release()
    cv2.destroyAllWindows()

except Exception as e:
    print(e)
    sys.exit(-1)

五、遇到的报错

CMake Error at CMakeLists.txt:1012 (add_subdirectory): 
The source directory 
 
E:/job/2.0/openpose-1.7.0/3rdparty/pybind11 
 
does not contain a CMakeLists.txt file. 
 
 
CMake Error at python/openpose/CMakeLists.txt:6 (pybind11_add_module): 
Unknown CMake command "pybind11_add_module". 
 
 
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. 
Please set them or make sure they are set and tested correctly in the CMake files: 
Caffe_LIB_DEBUG 
linked by target "openpose" in directory E:/job/2.0/openpose-1.7.0/src/openpose 
Caffe_LIB_RELEASE 
linked by target "openpose" in directory E:/job/2.0/openpose-1.7.0/src/openpose 
Caffe_Proto_LIB_DEBUG 
linked by target "openpose" in directory E:/job/2.0/openpose-1.7.0/src/openpose 
Caffe_Proto_LIB_RELEASE 
linked by target "openpose" in directory E:/job/2.0/openpose-1.7.0/src/openpose

主要是因为克隆openpose-master时丢失文件导致，重新克隆或下载补充文件。

六、报错no module named ‘pyopenpose’
6.1、降级python到 python 3.7.0 。必须是3.7.0版本
官网下载python3.7.0安装或conda虚拟环境中pip install python==3.7.0

6.2、CMAKE重新配置，可以删除之前build也可新建build2



必须选择pythonw.exe,然后进行configure

选择BUILD_PYTHON （必须）

选择以下五个模型（必选）

检查是否勾选，没勾选的进行勾选


然后进行configure，直到configure done

七、vs——方案重建
configure done完成后，点击Generare，configure done完成后，再点击open project

进入vs，将Debug改为release，将openposeDemo设为启动项目

建设方案

完成后在.\openpose-master\build\python\openpose\Release 中生成pyd文件

把build/bin里面的全部dll，复制到/build/python/openpose/Release
之后在pycharm或cmd中选择环境，运行\build\examples\tutorial_api_python中py文件
还会报错如下图：

增加37行代码

再run，成功
