Solvedopenpose Python API error: Cannot import name pyopenpose

When I execute the python API sample code in build folder ( 1_body_from_image.py ), the terminal return back the following errors. I also noticed that the python API have been changed during the past month. I am using ubuntu 16.04. cuda 8.0 with cudnn 5.1. The openpose is current version. Any suggestions?

Thanks!

from openpose import pyopenpose
Traceback (most recent call last):
File "", line 1, in
File "/home/jack/Documents/computervision/openpose/build/python/openpose/init.py", line 1, in
from . import pyopenpose as pyopenpose
ImportError: cannot import name pyopenpose

My environment - UBUNTU 18.04, CUDA 9.2, CUDNN 7.2.1
Openpose current version 1.4 (Jan 2019)

I did the following to get it to work

a. After a successful build, go look for the file - build/python/openpose/pyopenpose.cpython-36m-x86_64-linux-gnu.so and copy to /usr/local/lib/python3.6/dist-packages

b. in /usr/local/lib/python3.6/dist-packages I create a symbolic link - sudo ln -s pyopenpose.cpython-36m-x86_64-linux-gnu.so pyopenpose

c. Verify that your LD_LIBRARY_PATH from env has the entry /usr/local/lib/python3.6/dist-packages

d. Now, go to build/examples/tutorial_api_python and do some modification to 1_body_from_image.py

i) look for the line from openpose import pyopenpose as op and change to import pyopenpose as op

ii) Under custom parameters, I modify the following to reduce net_resolution (otherwise I hit a CUDA out of memory error ) and modify the model_folder to where I store the models

params = dict()
params["model_folder"] = "/home/XXXXX/openpose/models/"
params["net_resolution"] = "160x80"

go to your examples/tutorial_api_python and execute ./1_body_from_image.py

This version of Python Wrapper is indeed faster !

I met the same issuse as you in Windows10!!! After configure in CMake with PYTHON_BUILD flag , I found diffculty in Python . When try to run the demo , i got as follows:
ImportError: No module named 'pyopenpose'

JUST run make install in /openpose/build/python/openpose.

This worked for me. Thank you.

Make sure you are building with the correct python version or using the python version you built for. For me the problem was that python %example_file.py% was calling python 2.7 when I had built for python 3.5 (Which is only executed if I run python3 %example_file.py%)

JUST run make install in /openpose/build/python/openpose.
