Dear lyhour,
Thank you for your response!
I've tried that before and work nicely, if you want to reduce path directory you can jump into python file on Metashape instalation then reduce the command from "%programfiles%....." to "%python.exe%" -m pip install something.
So.. my conclusion is impossible for us to install external module from Metashape's console right? If it possible we can add our python script with pip install before we run the script, but its not gonna work..
Thank you
