有没有好心的大老看一下

我现在已经将图像文件夹内的所有图像都进行了预处理,并且保存到了一个图像列表中,在我将图像列表送入模型进行预测的时候在predictions处出现了ValueError(原来图像文件夹内有18张图像),请问大老我的代码该如何修改(我想将图像列表中所有图像作为一个整体进行预测)

你把报错信息复制出来发给我

import os
import cv2
import numpy as np
from tensorflow import keras

def preprocess_image(image_path):
    # Load image
    image = cv2.imread(image_path)
    # Resize image
    resized_image = cv2.resize(image, (224, 224))
    # Convert color channels from BGR to RGB
    rgb_image = cv2.cvtColor(resized_image, cv2.COLOR_BGR2RGB)
    # Normalize image data
    normalized_image = rgb_image / 255.0
    return normalized_image

def predict_images(image_list, model_path):
    # Load model
    model = keras.models.load_model(model_path)

    # Create an empty list to store the predictions
    predictions = []

    try:
        for image_path in image_list:
            # Preprocess the image
            processed_image = preprocess_image(image_path)
            # Add an extra dimension to match the input shape of the model
            input_image = np.expand_dims(processed_image, axis=0)
            # Predict image class probabilities
            prediction = model.predict(input_image)
            # Get the predicted class label
            predicted_label = np.argmax(prediction, axis=1)
            predictions.append(predicted_label)

        return predictions

    except ValueError:
        return "ValueError occurred during prediction."

# Set the path to the image folder and the model file
image_folder = "path/to/image/folder"
model_file = "path/to/model.h5"

# Get a list of image file paths from the image folder
image_list = [os.path.join(image_folder, file) for file in os.listdir(image_folder) if file.endswith(".jpg")]

# Call the predict_images function
result = predict_images(image_list, model_file)

将以上代码中的 "path/to/image/folder" 替换为你的实际图像文件夹的路径,将 "path/to/model.h5" 替换为你的实际模型文件的路径。此代码中使用了 OpenCV 来读取和处理图像,并使用了 TensorFlow 的 keras 来加载和预测模型。preprocess_image 函数用于图像的预处理,将其调整为模型所需的尺寸,并进行归一化处理。predict_images 函数用于对图像列表进行预测,循环遍历每个图像进行预测,并将预测结果存储在一个列表中。如果在预测过程中出现 ValueError,将返回相应的错误信息。
