Hi and sorry for the slow response.
Have you made sure you have a fully functioning deeplabcut-live python environment already? Generally this error is caused when embedded python is not able to properly import DLC-live modules from the Python virtual environment.
As for the location of the DLCwrapper.py, it should be located within the 'Scripts' folder of where ever you extracted the .zip file of the Miniscope DAQ software.
