Running errors with

Hi, I get the following error messages when running with the picar-x. Any help with this please?

Traceback (most recent call last):
File “/home/irene/picar-x/example/”, line 7, in
px = Picarx()
File “/usr/local/lib/python3.9/dist-packages/picarx-0.0.1-py3.9.egg/picarx/”, line 39, in init
self.camera_servo_pin1 = Servo(PWM(servo_pins[0]))

super().init(channel, *args, **kwargs)

self.timer = int(channel/4)
TypeError: unsupported operand type(s) for /: ‘PWM’ and ‘int’

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

NameError: name ‘px’ is not defined

We have re-updated and uploaded the code, because the code branch for downloading and installing robot-hat and vilib libraries has changed, so we recommend that you reinstall your Raspberry Pi system and go back and reinstall our code base.
