Tf-pose-estimation: Pafprocess import Error

[siddharthrajpatel]

Hi, I am not able to import pafprocess while running the realtime webcam command:
python src/run_webcam.py --model=mobilenet_thin --resolution=432x368 --camera=0

also i have used to do the following command to solve this issue by compiling pafprocess first by command:
swig -python -c++ pafprocess.i && python setup.py build_ext --inplace

but still getting this error while running this command itself as:

I dont know what to do...

[ildoonet]

I don't know neither. But, I guess the error comes from the compilation environments. Please check your build information.

[siddharthrajpatel]

@ildoonet Hi! I've someway managed this error by replacing (in pafprocess.cpp file) all "or" with "||" and all "and" with "&&". Also it need to change the round function name (i've named it as "rounds") beacuse it collides with cmath round function. Now you have just to run "swig -python -c++ pafprocess.i && python setup.py build_ext --inplace " and it will compile. Then should work everything (hope it!)

[ildoonet]

Yeah 'or' and 'and' are supported by higher version of c++ compiler. So I guess that yours is quite outdated.

Thanks for sharing the solution.

[rawandeheliah]

i fixed it by using the command in this way :
swig -python -c++ pafprocess.i setup.py build_ext --inplace
