如何将腌制的 python object 导入 Django view.py 文件

Question

This file runs perfectly well on its own:

import pickle

with open('model.obj', 'rb') as f:
    model = pickle.load(f)

print(model)

But what I really want to do is to use model, which is a very large stored python dictionary, in my Django views.py file, like so:

from django.shortcuts import render
from modeler.load_model import model

def page(request):
    return render(request, 'page.html', {'model':model})

However, when I try this, I get the error below:

 File "C:\Users\mmm\PycharmProjects\MyProject\modeler\load_model.py", line 3, in <module>
    with open('model.obj', 'rb') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'model.obj'

I don't understand why, because if I run the first file directly it works fine - the only extra step here is importing it into views.py (I tried including the entire load_model.py code within views.py at first, but got this error, so then tried it in this separate file and it worked on its own, so obviously the issue is that I don't know how to correctly load/import my python model objects or files within Django.

I found the answer, Apparently. all I had to do was to put the absolute path to 'model,obj' in my open statement, not just the relative path: like this:

with open('C:\\Users\\mmm\\PycharmProjects\\MyProject\\modeler\\model.obj', 'rb') as f:
    model = pickle.load(f)
