I want to detect the MAC address of KeiganMotor's motor by executing the script of KM1Scan.py from the above URL to the source code (Github), but the following error occurred.

Error message
Traceback (most recent call last):

After pip install bluepy input, it was executed with python3 KM1Scan.py, but the above error came out,
After entering sudo pip install bluepy, I tried sudo python3 KM1Scan.py, but the result did not change. I would be pleased to tell you how to detect the MAC address of KeiganMotor's motor.

I am using ubuntu18.04 in WSL environment
