Dave met this problem when trying to recognize traffic light. Importing python function failed. To solve the problem，try install opencv-contrib-python. Someone said that aruco is not in opencv-python, but in opencv-contrib-python.
pip install --upgrade pip pip install opencv-contrib-python
pip3 install --upgrade pip pip3 install opencv-contrib-python
