将深度学习模型导入Django

Question

Background

I was building a demo search engine and met a problem of loading my DL models into django . My code is basically structured like this:

models/
    DPR.py       # save model defination
utils/
    manager.py   # save model hyperparameter settings
backend/
    SearchApp/
        app.py   # where I want to load my model
        view.py  # where I want to use my model

To clarify, my model should be initialized this way:

from utils.manager import Manager
from models.DPR import DPR

manager = Manager()
model = DPR(manager)

Problems

1. I want to load the model once after the django app run.
2. I failed to load the model in backend/SearchEngine/app.py as suggested in here because of ImportError: attempted relative import beyond top-level package .

So any idea? Thanks in advance.

Answer 1

Solved by

class Backbone():
    import sys
    sys.path.append("..")

    from models.DPR import DPR

in backend/SearchEngine/app.py , after which I can from.apps import Backbone to use the model.
