Openpose: [QUESTION] When executing openpose Python API examples09：~/openpose/build/examples/tutorial_api_python/09_keypoints_from_heatmaps.py

[Pinocchioo]

ubuntu:20.04,cuda:10.02,cudnn:7.6.5,python:3.6.12 installed by conda,cmake:3.16.3,
Pybind11 module report errors when executing openpose Python API examples09：09_keypoints_from_heatmaps.py.The error report is as follows：

Starting OpenPose Python Wrapper...
Auto-detecting all available GPUs... Detected 1 GPU(s), using 1 of them starting at GPU 0.
emplaceAndPop(): incompatible function arguments. The following argument types are supported:
    1. (self: openpose.pyopenpose.WrapperPython, arg0: std::vector<std::shared_ptr<op::Datum>, std::allocator<std::shared_ptr<op::Datum> > >) -> bool

Invoked with: <openpose.pyopenpose.WrapperPython object at 0x7fab91920e30>, [<openpose.pyopenpose.Datum object at 0x7fab91920fb8>]

Did you forget to `#include <pybind11/stl.h>`? Or <pybind11/complex.h>,
<pybind11/functional.h>, <pybind11/chrono.h>, etc. Some automatic
conversions are optional and require extra headers to be included
when compiling your pybind11 module.

I compile the library by cmake —— make -j —— make install the source code that git clone from the openpose git. After installing the openpose library, I ran the python API example and reported an error.
cmake-gui: What I modified is：

BUILD_PYTHON ON
Add_Entry:
PYTHON_EXECUTABLE = /home/pinocchio/anaconda3/envs/openpose/bin/python3.6m
PYTHON_LIBRARY = 
/home/pinocchio/anaconda3/envs/openpose/lib/libpython3.6m.so

I didn't make any changes to the source code. I just installed the library, and ran the example.
And I don't know why ,I hope someone can answer it. Thank you very much.

I met this problem in latest openpose V1.7 from git downloading. Now this problem has been solved, after I downloaded the v1.6 relsaseed version of the openpose.
So I think the official examples have some wrong place in latest openpose_python_api example_09.

And someone had also met this problem.

After changing openpose from 1.7 to 1.6, python api works finally. Thanks! :)

Are you sure, I just got the latest version from master, and running:

python3 08_heatmaps_from_image.py

works for me

@gineshidalgo99 Is V1.7 referencing current master?

@gineshidalgo99 Is V1.7 referencing current master?

What the problem I met is :

python 09_keypoints_from_heatmaps.py

And python 08_heatmaps_from_image.py in V1.7 latest is also works for me.

Yes, you are right.

Line 58 is suppose to be:

opWrapper.emplaceAndPop(op.VectorDatum([datum]))

Would you like the opportunity to make a PR, or shall i push the fix

My Pr:
https://github.com/CMU-Perceptual-Computing-Lab/openpose/pull/1794
But it report error , maybeopWrapper.emplaceAndPop(op.VectorDatum([datum])) is incorrect .
