Permission Error Loading Pretrained Model, Django, AWS

I’m working on deploying a Django app on AWS. Locally, everything works well. When deployed, the website opens fine, but when i try to run a deep learning model it gives me an Errno 13 Permission Error. /severity is the page of the website where this occured. Any and all help is appreciated 🙂
