I am using pickle to save something to a file, and am trying to check if the thing loaded back in is the exact same as the thing that was saved to the file, for later in the program and am receiving the error message:

  File "(Directory blurred for privacy)", line 28, in <module>
    if newvalues == myvalues:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

when I try to check if they are equal to each other. Does anyone know how to fix this? I’ve tried iterating through them both and checking if each element is the same, and if any element is different, then it tells me, but this also returns the same error. I am using python 3.10 in Pycharm. The outputs from print(type(myvalues)) and print(type(newvalues)) are both the same thing, which is <class 'list'>

my code is here:

print ("start")
import mnist_loader
training_data, validation_data, test_data = mnist_loader.load_data_wrapper()

import network
net = network.Network([784, 30, 10]) # amount of neurons in each layer is the numbers

net.SGD(training_data, 2, 10, 3.0, test_data = test_data)

myvalues = net.getWeightsAndBiases()


# Saving it - not part of the code from book
print("n n n")
with open("data.pickle", "wb") as file:
    pickle.dump(myvalues, file)

with open("data.pickle", "rb") as file:
    newvalues = pickle.load(file)

print(newvalues)

print("myvalues is:", type(myvalues))
print("newvalues is:", type(newvalues))
if newvalues == myvalues:
    print("working")

the imports come from this github repo: https://github.com/unexploredtest/neural-networks-and-deep-learning with an addition to the Network class in the network file of:

def getWeightsAndBiases(self):
    weightsandbiases = [self.weights, self.biases]
    print(weightsandbiases)
    return weightsandbiases

I tried to see if this error was encountered before, and found this question: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all(). I tried what was suggested on there, but it didn’t solve the problem.

here are the values stored:
