Openpose: Problems on testing python files on Windows system

[Jichen66]

Hi,

First of all, thanks for the great job of openpose.

By following the installation guide on Windows, I have built it successfully on Win10 system, and can run it successfully through Visual Studio 2017. But I also want to test it in python. And when I run 01 body_from_image.py (or any other python file in that file) from the path of '\openpose\build\examples\tutorial_api_python', the errors 'No module named pyopenpose' occured. I have also chose the 'build_python' in cmake and have checked the similar issues online, but could not fix it. Does anyone met similar issues and have any idea on how to solve it? I am looking forward to the reply. Many thanks in advance!

Make sure that openpose path points to correct folder. In my case its path_to_openpose/openpose/build/python

[Jichen66]

thx a lot, I have checked the path you said, there is no any .py file in this path. Is there anything wrong?

[andriy-tsvikla]

My bad, that folder is for Linux, for windows check python/openpose/Release
I have this files there, maybe this will help with your investigation.

pyopenpose.cp37-win_amd64.pyd
pyopenpose.exp
pyopenpose.lib

In my case i just hardcoded path to this folder and it worked.

[Jichen66]

thx a lot again! I have checked and I found these files exist in 'path to
openpose\buildpython\openpose\Release'. Is this correct?

should be.
This is quote from example.

 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

basically dir_path + '/../../python/openpose/Release' this path needs to be specificed

[Jichen66]

Thank you so much! I have checked that path and made a little modification(previously the path is not in build folder), and I print them out:

Did you enableBUILD_PYTHONin CMake and have this Python script in the right folder? No module named 'pyopenpose'

Could you help me find the problems through it?

[Jichen66]

And this is the part I changed:

    if platform == "win32":
        # Change these variables to point to the correct folder (Release/x64 etc.)
        sys.path.append(dir_path + '/../../build/python/openpose/Release');
        print(dir_path + '/../../build/python/openpose/Release')
        os.environ['PATH']  = os.environ['PATH'] + ';' + dir_path + '/../../build/x64/Release;' +  dir_path + '/../../build/bin;'
        print(os.environ['PATH'] + ';' + dir_path + '/../../build/x64/Release;' +  dir_path + '/../../build/bin;')
        import pyopenpose as op

Hi, I followed the tutorial and ran into the same problem (No module named 'pyopenpose') when I tried the python APIs in Win10. I checked the path, they are all good. And also I get pyopenpose.cp36-win_amd64.pyd in /python/openpose/Release. The demo runs perfectly in VS 2017.
Python 3.5.6
OpenCV 3.3.1

Hello, I followed the tutorial and same problem ... but got a:

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

Still have no idea...Hope someone could me help me solve this problem. Many thanks in advance!

[24Beast]

Hey, was anyone able to solve this problem ?
If yes please share the solution cause I am facing the exact same problem as nyudeb

Edit:
The problem is not with the library but, your opencv or numpy library updated them in a new environment after reading this issue.

If the libraries are not compatible with pyopenpose, it will give the same error!

[analogously]

I have the same issue. Win10, Python 3 - CUDA 10 - Visual Studio 2019, demo works and the content of my path seems to be correct according to the others, but no module named openpose.

Can you explain the edit further? I don't understand.

You need to build the project first(Ctrl + Shift + B)

Hi, I am also facing the exact same problem as nyudeb. I have checked all the path and got everything as nyudeb mentioned and got the same error.. So have anyone solve this problem? Thx in advance!!

[ABODFTW]

I've faced this same problem, and I couldn't find a solution, hope this helps someone.
I fixed it by downgrading the python version to 3.7 (I was using python 3.8), and make sure to update the PYTHON_EXECUTABLE in CMake, to point to python 3.7 directory, and make sure to enable "BUILD_PYTHON", and on visual studio, make sure to build on "Release" mode, make sure to click "build" at the top then "build solution" because sometimes pressing the green tringle is not enough.

[Jichen66]

@ABODFTW
So did you run Openpose on Win10 using Python successfully?

[PrototypeNx]

Thx a lot! I changed my python version to 3.7 ,and it works!

[Jichen66]

Thx a lot! I changed my python version to 3.7 ,and it works!

Good to hear! Btw, you mean you can run Openpose successfully in Python now?

[ABODFTW]

Thx a lot! I changed my python version to 3.7 ,and it works!

Sorry just read your question, Yes, I have got OpenPose/Pyopenpose working on my Win10 machine

To make it work on Python 3.8 on Windows please look at

[D0683406]

I had same problem, and my solution is after I cmake my openpose project, Set "example" as StartUp project in Visual Studio , then i can run the examples.
