尝试打开 pickle 文件时出现“int object 不可调用”？

Question

I am working for a team of scientists and have been given a pickle file we'll call theFile.p . I am trying to open and load the Pickle file via

opened_file = open("theFile.p", "rb")
loaded_data = pickle.load(opened_file)

but am getting the error

    loaded_data = pickle.load(opened_file)
                     ^^^^^^^^^^^^^^^^^^^^^
TypeError: 'int' object is not callable

Now I know that error means you either forgot an arithmetic operator somewhere or you declared a variable name that matches a built in function name (eg max = max(1, 2) ). I am wondering if this means there is some sort of issue inside the theFile.p that's causing this error, and if so, how would I go about debugging the Pickle file if I can't even open it? Or maybe it's an issue with me being on Python 3.11 and the pickle file was made on an older version Python?

Full traceback can be seen here

Answer 1

Although I do not believe that this applies to you specifically, but I will still ask this to check, as anyone can make this mistake: have you imported the pickle plug-in?

Updated: I was looking up how to load data with a pickle file and I came across many code excerpts with the same difference to yours. Now, I do not know whether this affects anything or not, but in all of the code excerpts I've seen, there has been no.p to open the pickle file.

Answer 2

import pickle

with open("theFile.p", "rb") as opened_file:
loaded_data = pickle.load(opened_file)
