Python • SparkFun Auto pHAT

I tried to import qwiic to python3 to use sparkfun auto phhat to run srvo motor, but I received an error
Invalid driver class name. Unable to locate QwiicAs6212
Invalid driver class name. Unable to locate QwiicKx13X

then I tied to assign s=qwiic.PiServoHat(), and received the following error

I tried to use s=pi_servo_hat.PiServoHat() and received the folloing error
