flask 应用程序:Flask 应用程序显示 HTML 文件,而不是将其呈现为网页
flask app: Flask application is displaying the HTML file, not rendering it as a web page
问:
我有一个经过训练的机器学习模型,我想在 Flask Web 应用程序中使用它。当我运行 Python 代码 (app.py) 时,Flask 应用程序将 HTML 文件显示为纯文本,而不是将其呈现为网页。下面是我的 Python 代码 (app.py) 和我的 HTML 代码 (index.html)。我是 Web 开发的新手,我正在寻求有关如何解决此问题的指导。任何协助将不胜感激。谢谢你的帮助。
from flask import Flask, request, render_template,url_for
import numpy as np
from tensorflow.keras.models import load_model
from tensorflow.keras.preprocessing import image
import os
app = Flask(__name__)
#Load your trained CNN model
model = load_model(os.path.join('models', 'BreastCancerDetection.h5'))
@app.route('/')
def home():
return render_template('index.html')
@app.route('/predict', methods=['POST'])
def predict():
# Get the uploaded image from the request
uploaded_file = request.files['BreastUltrasoundImage']
# Process the uploaded image
img = image.load_img(uploaded_file, target_size=(256, 256))
img_array = image.img_to_array(img)
img_array = np.expand_dims(img_array / 255, axis=0)
# Make predictions
predictions = model.predict(img_array)
class_labels = np.argmax(predictions, axis=1)
return render_template('index.html', predictions=class_labels[0])
if __name__ == '__main__':
app.run(debug=True)
我的索引.html是:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Breast Cancer Detector</title>
</head>
<body>
<h1>Breast Cancer Prediction</h1>
<div>
<form action="{{ url_for('predict') }}" method="post" enctype="multipart/form-data">
<input type="file" name="BreastUltrasoundImage" accept="image/png, image/jpeg" required>
<button type="submit">Predict</button>
</form>
<h4 style="color: violet;">{{ predictions }}</h4>
</div>
</body>
</html>
我检查了我的目录,如下所示。
project_folder/
├── app.py
├── templates/
│ └── index.html
└── models/
└── BreastCancerDetection.h5

此问题已解决。我从 TextEdit 切换到 Atom 来编写我的 html 代码,第二个变化是用于上传图像的 python 代码:
@app.route('/upload', methods=['POST'])
def upload_file():
uploaded_file = request.files['BreastUltrasoundImage']
if uploaded_file:
file_contents = uploaded_file.read()
return file_contents
谢谢
