我已经为我的存储库创建了一个工作流程，一切甚至部署都进展顺利，我已经在与 docker 相同的环境中创建了模型，并且工作流程正在运行，但我仍然得到了这个：

请帮我修复代码。我还提供了views.py：
from django.shortcuts import render
from joblib import load
import requests
import os
from django.conf import settings
from django.views.decorators.cache import never_cache
# Create your views here.
def home(request):
return render(request, 'index.html', {'movies_list': movies_list['title'].values})
def fetch_poster(movie_id):
response=requests.get('https://api.themoviedb.org/3/movie/{}?api_key=fbb18fe9735d1a3e0ad1531398ed1b13'.format(movie_id))
data=response.json()
return 'https://image.tmdb.org/t/p/w500/'+ data['poster_path']
movies_list_path = os.path.join(settings.BASE_DIR, 'savedmodels/movies.joblib')
model_path = os.path.join(settings.BASE_DIR, 'savedmodels/similarity.joblib')
movies_list =load(open(movies_list_path, 'rb'))
similarity = load(open(model_path,'rb'))
def recommend(movies_list, movie):
movie_index = movies_list[movies_list['title'] == movie].index[0]
distances = similarity[movie_index]
movie_list = sorted(list(enumerate(distances)), reverse=True, key=lambda x: x[1])[1:7]
recommended_movies = []
recommended_movies_posters = []
for i in movie_list:
movie_id = movies_list.iloc[i[0]].id
recommended_movies.append(movies_list.iloc[i[0]].title)
# fetch poster from API
recommended_movies_posters.append(fetch_poster(movie_id))
return recommended_movies, recommended_movies_posters
@never_cache
def recommend_movies(request):
if request.method == 'POST':
selected_movie_name = request.POST['movie_name']
names, posters = recommend(movies_list, selected_movie_name)
return render(request, 'recommend.html', {'movie_data': zip(names, posters), 'movies_list': movies_list['title'].values})
return render(request, 'index.html', {'movies_list': movies_list['title'].values})
我尝试在环境中再次创建模型并使用 git-lfs 来处理大文件，但仍然收到此错误
检查模型路径：确保views.py 文件中的model_path 变量正确指向模型文件的位置。考虑到您的项目结构和部署环境，它应该是绝对路径或正确解析相对路径。
文件存在：验证部署环境中指定路径下是否存在模型文件。您可以添加一些日志记录或调试语句来确认这一点。
文件权限：确保应用程序具有读取模型文件所需的权限。检查Docker容器或部署环境中的文件权限。
或者您只需添加更多调试
