UnpicklingError : invalid load key,'v'

Hi All
I have used git lfs to upload my pickle file to github since it was larger than 25mb but on deploying my app on heroku I am getting this error :

Stuck on this error from last 3 days. Really appreciate help on this one.

Hi @Gunpreet_Singh, welcome to the Streamlit community!

Pickle errors in my experience are usually a case that you are using a different version of Python than the one that was used to create the Pickle. In your heroku build script, I would try specifying the exact version of Python and re-deploy.

Best,
