Hi, I currently have opencv4 on my pc. However, the program I am running only works for opencv3. I downloaded opencv3 using pip install on the command prompt of my pc. However, I do not know how to make opencv3 my default version when I run my python program. Thank you!
venv
and virtualenv
is the usual solution for this.
modules are installed into such an environment rather than system-wide.
this isn’t specific to OpenCV but to Python. you’ll find information on the internet.
