Boost.Python.ArgumentError

[mcarletti]

Hi,

I got the following error when running the code under the following setup:

Ubuntu 16.04 (4.4.0-97)
Python 2.7.12
OpenCV 3.3.0.10
DLib 19.7.0
SciPy 0.19.0

Traceback (most recent call last):
File "demo.py", line 49, in
demo()
File "demo.py", line 28, in demo
lmarks = feature_detection.get_landmarks(img)
File "~/face-frontalization/facial_feature_detector.py", line 22, in get_landmarks
predictor = dlib.shape_predictor(predictor_path)
Boost.Python.ArgumentError: Python argument types in
shape_predictor.__init__(shape_predictor, str)
did not match C++ signature:
__init__(boost::python::api::object, std::string)
__init__(_object*)

This is the line 22 of facial_feature_detector.py file:

predictor = dlib.shape_predictor(predictor_path)

Any ideas? What should I change to make the code work?
Thank you.

Hello,

This looks like an error from dlib itself. Have you tried building dlib from source? Also, check your version of boost python to see if it is supported by dlib. If it doesn't help, I suggest looking for help in their community, they are very helpful.

Cheers,

Douglas
