I encountered a problem using rshell

Do you know why ? If yes, how to fix it?
I leave you a screenshot attached.
Here are the command line:
d: #in order to connect to the correct disk
python CAMERA.py #run a python script using the webcam
rshell #in order to connect to the pyboard
repl ~ exec(open('motor.py').read()) ~ #run a script on the pyboard allowing to run motors
Thank you in advance for your help!
