Hello,

Question from a beginner.
It seems that the import cv2 failed

python3 depthai_supervisor.py
python3 depthai_demo.py
Traceback (most recent call last):
File "/Users/pp730662/depthai/depthai_demo.py", line 7, in <module>
import cv2
ModuleNotFoundError: No module named 'cv2'
Return code:1

Can you help?
Thanks in advance

    Hello Sceletus ,

    Did you run the following command?
    python3 install_requirements.py
    If you did and it still doesn't work, please execute the following command and send us your output so we can see if there an issue with our requirements.
    python3 -m pip freeze
