I am using conda virtual environment on Ubuntu 20.04 and I got this error while using "make" in Darknet folder even if my virtual environment(conda) has Opencv installed.
Here is the screenshot of the error:
Here is that cv2 is working and its version(4.5.5):
Here is the environment variables for CUDA and Opencv I used (in .bashrc):
Thanks in advance for your any help!
It seems that the problem is originated from not building OpenCV as Darknet needs.
As @ChristophRackwitz implied, showing python version worked is not enough to build darknet with OpenCV capability. To be able to build darknet with OpenCV ON, OpenCV should be built with C++ functionalities as some of instructions might be followed:
Instruction 2 and so on.
