Ubuntu flask 应用程序看起来无法正常工作，因为它试图在已删除的部分代码中查找文件

Question

你好，我正在尝试在 ubuntu 服务器（数字海洋水滴）上运行我的烧瓶应用程序，但我遇到了一些奇怪的错误。
错误消息说文件的路径不正确，但我已经更改了这个文件，现在它不包含任何路径所以我知道为什么我会看到这个错误。

这里是错误信息：

 File "/var/www/html/cancel-the-cancer/venv/lib/python3.10/site-packages/flask/views.py", line 107, in view
    return current_app.ensure_sync(self.dispatch_request)(**kwargs)
  File "/var/www/html/cancel-the-cancer/venv/lib/python3.10/site-packages/flask_restful/__init__.py", line 582, in dispatch_request
    resp = meth(*args, **kwargs)
  File "/var/www/html/cancel-the-cancer/Resources/predict.py", line 10, in post
    img = img.resize((256, 256))
  File "/var/www/html/cancel-the-cancer/venv/lib/python3.10/site-packages/werkzeug/datastructures.py", line 3002, in save
    dst = open(dst, "wb")
FileNotFoundError: [Errno 2] No such file or directory: './images/ISIC_0029612.jpg.jpg'

这里是

predic.py

文件：

import numpy as np
from flask_restful import Resource, request
import tensorflow as tf
from PIL import Image

class Predict(Resource):
    def post(self):
        file = request.files['image']
        img = Image.open(file.stream)
        img = img.resize((256, 256))
        img = np.array(img)
        img = img / 255.0
        img = np.expand_dims(img, axis=0)
        loaded_model = tf.keras.models.load_model('../model/vgg19_92%_93%')
        prediction = loaded_model.predict(img)[0][0]
        return {"result": float(prediction)}

这里是

app.py

文件：

import flask_restful
from flask_cors import CORS

from flask_cors import CORS
from flask import Flask
from flask_restful import Api

from Resources.predict import Predict

app = Flask(__name__)
app.secret_key = 'zwolnienizteorii44893'
api = Api(app)
cors = CORS(app)

api.add_resource(Predict, '/predict')

if __name__ == '__main__':
    app.run(port=5000, debug=True)

我还在装有 Windows 11 的个人计算机上尝试了相同的应用程序，在 win 上它运行良好并返回预测，但在 ubuntu 上作为 api 响应我收到内部服务器错误。

我在努力

sudo systemctl restart uwsgi

sudo systemctl restart nginx

sudo systemctl reload uwsgi

sudo systemctl reload nginx
