Pickle Not Dumping Everything?

I am currently working on a simple robot, and am looking to use Pickle to store the main object of the robot. Trying to interact with components initially declared does not seem to be working however. The code for storing and reading the item is shown below. It should be noted that this object here is in working order:

import pickle, os

from sys import argv

from zumicreator import ZumiCreator
from zumi.zumi import Zumi
functions = {"move_inches": "z.move_inches(fParam)"}

def getZumi():
    file = open(os.getcwd() + "/Code/lib/state", "rb")
    zumiHousing = pickle.load(file)
    return zumiHousing

def main():
    if argv[1] == "create":
        
        # Create the Zumi object
        # and store it with pickle.
        
        zumiHousing = Zumi()
        file = open(os.getcwd() + "/Code/lib/state", "wb")
        pickle.dump(zumiHousing, file)

        print('Dump Successful!')
        
        # Exit since that is all we 
        # needed to do.
        quit()
        
    # ! Do NOT change ANY of the following variable names! 
    z = getZumi()
    fName = argv[1].split()[0]
    fParam = str(argv[1].split()[1:]).replace("[", "").replace("]", "").replace("'", "")

    # Runs the function with the desired arguments.
    eval(functions[fName])
    
if __name__ == '__main__':
    main()

As you may have guessed, the object has a method named: move_inches. The object is created in the if block, and referenced in main function.

I am receiving this error when using the object that has been read in:

Traceback (most recent call last):
  File "/home/pi/.local/lib/python3.5/site-packages/zumi/zumi.py", line 526, in __read_raw_MPU_data

During handling of the above exception, another exception occurred:

  File "/home/pi/.local/lib/python3.5/site-packages/zumi/zumi.py", line 533, in __read_raw_MPU_data
    return self.__read_raw_MPU_data()
TypeError: __read_raw_MPU_data() missing 1 required positional argument: 'addr'

This leads me to believe that I cannot store the object like such.

Does anyone know any alternatives to store the entire state of the object, or prevent calling the constructor again?

Thanks!
