I have a Python Flask app on Heroku. There are 3 Top2Vec trained models that I'm trying to load as global variables in app.py, before first request:

@app.before_first_request
def models():
  global model1
  global model2
  global model3
  model1, model2, model3 = load_models()

load_models() method, just the standard load call defined in the Top2Vec library:

def load_models():
return [Top2Vec.load(MODEL1_PATH), Top2Vec.load(MODEL2_PATH),
        Top2Vec.load(MODEL3_PATH)]

where MODEL1_PATH, MODEL2_PATH, MODEL3_PATHare the absolute path to the model file.

When I try to open the app localy, everything works fine, but when I open the hosted web app, I get:

All three models are files larger than 100MB and are uploaded with git lfs and I suspect, this might play a role in the error I'm getting. Any ideas why I'm getting this and how to fix it? Am I making some rookie mistake?
