Description

  • ev3dev version: 4.14.117-ev3dev-2.3.5-ev3
  • ev3dev-lang-python version: micropython-ev 2.1.0, python3-ev3dev 1.2.0, python3-ev3dev 2.1.0

I have Windows 10, latest ev3dev version installed in EV3. I am using Visual Studio Code to program the robot. EV3 is connected to Internet through microUSB cable and everything works nice with SSH. I am trying to install OpenCV library to ev3dev using the terminal and I get this error:

The following packages have unmet dependencies:
 python3-opencv : Depends: libopencv-calib3d3.2 (= 3.2.0+dfsg-4ev3dev1) but it is not going to be installed

 Depends: python3-numpy-abi9 but it is not installable
 Depends: libopencv-contrib3.2 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So I can't make a project that combines opencv and ev3dev. Any help ?
