Import error : undefined symbol: load_image_cv

[aic25]

I try to install with GPU + OpenCV + CUDNN + OpenMP (Darknet is built with GPU + OpenCV + CUDNN + OpenMP as well)
install script (it is running in a docker container as root so no need for sudo):

#!/bin/bash
rm -rf build
rm /usr/local/lib/python3.5/dist-packages/pyyolo*
make
python3 setup_gpu.py build
python3 setup_gpu.py install
python3 -c "import pyyolo;"

I get the following after running it:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/local/lib/python3.5/dist-packages/pyyolo.cpython-35m-x86_64-linux-gnu.so: undefined symbol: load_image_cv

This is the MakeFile:

I built OpenCV 3.4.3 from source.
cuDNN v7
Python 3.5
CUDA 9.0

Thank you very much.

I'm having the exact same issue with almost the same settings on an aarch64 system.

OpenCV 3.4.0
