Potential Github LFS Issue

Hello! I’m pretty new to Streamlit Cloud. I have a pickled object (reorganized_meta.obj) that I’d like to use for my app. Here’s a code snippet of how I’m loading the model:

import streamlit as st 
import pickle 

@st.experimental_memo
def load(file_name):
    with open(file_name, 'rb') as fobj:
        data = fobj.read()
    meta = pickle.loads(data)
    return meta


@st.experimental_memo
def load_objects(): 
    raw_meta = load("./reorganized_meta.obj")
    return raw_meta

Although when deploying, I’m running into the following issue.

ModuleNotFoundError: No module named 'filter'

What does it mean that no module found named “filter”? The pickled obj that I’m trying to load is 171MB so I have it saved to my github repo as a LFS.

Would sincerely appreciate any advice! I don’t recall there being a module named “filter”. Though, I may be incorrect.

Additionally, I tried deploying the app with all available python versions. I’m not using any extra modules aside from pickle.
