'strict' is an invalid keyword

The error message "strict" is an invalid keyword usually occurs when a Python program tries to use the keyword "strict" in a way that is not valid.

However, "strict" is not a keyword in Python, so it may be caused by a typo or a problem with the syntax of the code.

To debug this error, check the code for any instances of "strict" being used as a keyword and ensure that the keyword is being used correctly. If the error persists, it may be helpful to provide more context or the specific code causing the issue.

'strict' is an invalid keyword argument for Unpickler()

The error message indicates that you are trying to pass an invalid argument "strict" to the Unpickler() function. This argument is not recognized by the function and therefore it raises an exception.

To fix this error, you should remove the "strict" argument or replace it with a valid one. The Unpickler() function only accepts a few optional arguments such as "encoding", "errors", and "fix_imports". You can check the documentation for more information on these arguments.

Here's an example of how to use the Unpickler() function without the "strict" argument:

import pickle

with open('data.pickle', 'rb') as f:
    data = pickle.load(f, encoding='utf-8', errors='ignore')

In this example, we're loading data from a pickle file using the Unpickler() function and specifying the "encoding" and "errors" arguments. These arguments tell the function how to handle any encoding errors that may occur during unpickling.
