I’m using git lfs to store a pickled model. Streamlit wouldn’t pull properly when the git attributes file existed. I deleted it and got much further in my deployment, then ran into the problem of not being able to load my pickle and I suspect it’s because the git attributes file is gone. I read through some threads and streamlit supports git lfs now. Not sure how to proceed. Error I get when trying to load the pickle and don’t have the git attributes file:,@randyzwitch Used python 3.7 to pickle and I’m still getting the same error. Same thing with the .gitattributes file as well. The first pickle model is loading fine so I’m guessing it’s something to do with the git LFS. Without the git attributes file, does the large file have a pointer to where it’s stored?,From my experience, pickle errors are usually due to a mismatch between the Python version used to create the file and what Streamlit sharing is using (3.7). What version of Python are you using locally?,@randyzwitch Hi Randy. I’ve managed to host my pickle on google drive. I’m now getting the following error: could not extract any ngrams from ’ ', returning origin vector Everything is working when I run it on my local machine using the input() function. Is it possible the following statement is causing an error? words = st.text_input()
