FileNotFoundError: [Errno 2] 图像数据集单热编码没有这样的文件或目录

Question

我尝试在我的图像数据集中使用 to_categorical() 进行单热编码，但由于 FileNotFoundError: [Errno 2] No such file or directory 错误而失败，代码如下，

import os
import numpy as np
from PIL import Image
from keras.utils import to_categorical

# Define the classes in the dataset
classes = ['BL_Healthy']

# Initialize the arrays to store the image data and labels
X = []
y = []

# Loop through the dataset and load each image
for class_id, class_name in enumerate(classes):
    for image_file in os.listdir('/content/imdadulhaque/' + class_name):
        image_path = os.path.join(class_name, image_file)
        image = Image.open(image_path)
        X.append(np.array(image))
        y.append(class_id)

# Convert the labels to one-hot encoded labels
num_classes = len(classes)
y = to_categorical(y, num_classes)

虽然有图像，但不幸的是，它显示错误文件未找到。附件中提到了所需的错误屏幕截图。有想法的请帮忙
