Load pickled object in different file - Attribute error

Question

I have some trouble with loading a pickled file in a module that is different from the module where I pickled the file. I am aware of the following thread: Unable to load files

Answer 1

I had a similar problem and only just realized the differences between our implementations.

Your file structure:

• util.py
  • define pickle functions
• class_def.py
  • import util
  • define class
  • make instance
  • call save pickle
• process.py
  • import util
  • load pickle

My mistake (using your file names) was first:

• util_and_class.py
  • define class
  • define pickle funcs
  • make instance
  • call save pickle
• process.py
  • import util_and_class
  • call load pickle << ERROR

What solved my pickle import problem:

• util_and_class.py
  • define class
  • define pickle funcs
• pickle_init.py
  • import util_and_class
  • make instance
  • call save pickle
• process.py
  • call load pickle

This had the welcomed side effect that I didn't need to import the util_and_class file as it's baked into the pickle file. Calling the instance and saving the pickle in a separate file resolved the __name__ issue of "loading a pickled file in a module that is different from the module where I pickled the file."
