6 years ago I think you may have misread our instructions. If you simply wish to test OpenPose Python, you must navigate to the python directory in the Python Build Folder as seen in the instructions (https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/modules/python_module.md)
# From command line
cd build/examples/tutorial_python
python 1_extract_pose.pyIf you wish to access the library from another location, you need to add the python folder to your PYTHONPATH. This can be done with adding it to your system path or appending the environmental variable directly. This can be seen in the example code as well
else: sys.path.append('../../python');
# Option b
# 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')In your case, you have installed openpose already to /usr/local/ so you need to add sys.path.append('/usr/local/python') instead of hacking the path of openpose.so directly into the python library. You have linked to the wrong .so library anyway so it can't find the symbol. Your python path is also pointing to the source directory openpose/python instead of openpose/build/python. If this folder is missing, it means you did not enabled BUILD_PYTHON. Please try to take a look at the examples and read the instructions to see how its done.
Lastly, the Python example currently does not allow command line inputs. It was more to serve as an example of what variables can be changed. But we can see how this can be confusing as the C++ code can do this, so we could add this in the future

Issue Summary
Either "_openpose.so" not found or if that is fixed then there's an undefined symbol error. As a result can't even run the example python script.
In openpose.py (location: openpose/python/openpose/openpose.py) I had to change line 16 to the following for it to work:
_libop= np.ctypeslib.load_library('libopenpose','/usr/local/lib/libopenpose.so')Also I just wanted to include what my PYTHONPATH looks like:
echo $PYTHONPATH/home/abdullah/caffe/python/:/home/abdullah/Desktop/openpose/python/Executed Command (if any)
python 1_extract_pose.py --logging_level 0 --disable_multi_threadOpenPose Output (if any)
