This article introduces the process of building an image recognition interface using Flask. First, a simple Flask program is used to set up the root path and file upload functionality; subsequently, the image prediction API is implemented, which loads the model and performs inference. After uploading an image, users can directly obtain the classification result and confidence. The entire process includes steps such as environment preparation, code writing, and deployment, making it suitable for beginners to learn the development method of image processing services. Key points: 1. **Flask Setup**: Create the root path and file upload functionality. 2. **Model Loading**: Load the model from PaddlePaddle
