Openpose: How to set python version?

[universewill]

My system is ubuntu16.04, and got python2.7 and python3.6

I set /usr/bin/python to python3.6. But after building openpose, it can only run by python2.
The 1_extract_pose.py demo will encounters error like below if run by python3:

Traceback (most recent call last):
  File "1_extract_pose.py", line 37, in <module>
    openpose = OpenPose(params)
NameError: name 'OpenPose' is not defined

As per the instructions, you need to set your PYTHONPATH to where OpenPose python is built. If you ran sudo make install, it'll install by default to /usr/local/python, so you would add this to your environmental variables:

export PYTHONPATH=/usr/local/python/:$PYTHONPATH

If you are on Ubuntu or OSX, you can add this to your .bashrc

I have found a solution for that problem. It works for me so here it go.
You need to import:
from openpose import openpose as op
And then use it as:
op.OpenPose(params)

I hope this help you!

I run 'sudo make install' and openpose is installed in /usr/local/python/ directory.
I also add the path as PYTHONPATH in ~/.bashrc file, and source it.
However, my python code still can not import OpenPose. Besides, the demo code in build/example/python_tutorial can execute well.

I add the openpose/build/python/openpose or openpose/build/python/ path by sys.path.append, and still didn't work.

I replace export PYTHONPATH=/usr/local/python/:$PYTHONPATH by export PYTHONPATH=/usr/local/python/openpose:$PYTHONPATH.
And problem solved!
