今天openpose完以后，运行stgcn的demo程序报错，运行的命令如下：

python main.py demo_offline --video ./resource/media/clean_and_jerk.mp4 --openpose /media/data/projects/A15697/openpose-master/build

然后出现如下的错误:

Starting OpenPose Python Wrapper...
Auto-detecting all available GPUs... Detected 1 GPU(s), using 1 of them starting at GPU 0.
Traceback (most recent call last):
  File "main.py", line 35, in <module>
    p.start()
  File "/media/data/projects/A15697/st-gcn-master/processor/demo_realtime.py", line 82, in start
    opWrapper.emplaceAndPop([datum])
TypeError: 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 0x7f2d5cd9bef0>, [<openpose.pyopenpose.Datum object at 0x7f2d5cd9bf70>]

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.

根据报错信息可以看出是82行出现了问题。

解决方法

opWrapper.emplaceAndPop([datum])

换成

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

就行了。
