when built opencv4.4.0, folder 'cv2' had been create in python's site-packages.
my env:
cuda 10.2
python 3.8
vs2017
cmake3.19

>>>import cv2
ImportError: DLL load failed while importing cv2 

then i used opencv's python_loader

>python setup.py install
>python
>>>import cv2
>>>ImportError: DLL load failed while importing cv2

Seems that you are not using this repository (pip install opencv-python), there is no python_loader here. Please open an issue to the OpenCV repository.
