OpenPose Python API调用：ImportError: cannot import name 'pyopenpose' from 'openpose'

OpenPose Python API 调用方法

可能出现的错误

• Error: OpenPose library could not be found. Did you enableBUILD_PYTHONin CMake and have this Python script in the right folder?
• 在这里插入代码片
• ImportError: cannot import name 'pyopenpose' from 'openpose'
• 上面的错误代表.py文件中from openpose import pyopenpose as op未执行成功
• 首先进入自己的python3 运行环境，依次运行以下命令
• ls /usr/local/python/openpose 观察是否有文件 pyopenpose.cpython-35m-x86_64-linux-gnu.so* 如果没有 进入build执行sudo make install
• 如果有pyopenpose.cpython-35m-x86_64-linux-gnu.so进行下面操作
• import sys
• sys.path
• 观察输出，是否有pyopenpose.cpython-35m-x86_64-linux-gnu.so所在目录
• 若没有，则在源代码py文件中加入sys.path.append('/usr/local/python/openpose')
• 另一种情况，如下图log
  
• 从上图可以发现目前python3关键字指向的是home下的anaconda
• 但是OpenPose默认编译的是/usr/local/python目录下的pyopenpose.cpython-35m-x86_64-linux-gnu.so*文件，使用的是系统python解释器
• sudo vim ~/.bashrc
• 发现这么一句话：export PATH=/home/ubuntu/anaconda3/bin:$PATH
• Now,everything is clear，这里声明了anaconda3下的python为默认解释器
• 在~/.bashrc中加入语句：alias py35=/usr/bin/python3.5 指定py35为系统python3.5的别称
• source ~/.bashrc
• 重新运行py35 01_body_from_image.py
• done…

新错误

Error:
Prototxt file not found: ../../../models/pose/body_25/pose_deploy.prototxt.
Possible causes:
	1. Not downloading the OpenPose trained models.
	2. Not running OpenPose from the same directory where the `model` folder is located.
	3. Using paths with spaces.

解决：

vim 01_body_from_image.py

修改第38行params["model_folder"] = "../../../models/"为`

params["model_folder"] = "../../models/"

新错误

a bytes-like object is required, not 'NoneType'

解决：

修改第33行parser.add_argument("--image_path", default="../../../examples/media/COCO_val2014_000000000192.jpg", help="Process an image. Read all standard formats (jpg, png, bmp, etc.).")为

：parser.add_argument("--image_path", default="../../examples/media/COCO_val2014_000000000192.jpg", help="Process an image. Read all standard formats (jpg, png, bmp, etc.).")
