python - 出现错误 : ValueError: too many values to unpack (expected 2)

Question

我正在练习 CNN 的“英特尔图像分类”，我编写了一个函数来从不同文件夹加载数据。但是当我调用该函数时，我收到一个 ValueError ，上面写着“太多值无法解压”。..知道如何解决这个问题吗？

def data_load():
datasets = ['seg_train\seg_train', 'seg_test\seg_test']
size = (150, 150)
output = []
for dataset in datasets:
    directory = os.getcwd() + '/' + dataset
    images = []
    labels = []
    for folder in os.listdir(directory):
        curr_label = class_labels[folder]
        for file in os.listdir(directory + '/' + folder):
            img_path = directory + '/' + folder + '/' + file
            curr_image = cv2.imread(img_path)
            curr_image = cv2.resize(curr_image, size)
            images.append(curr_image)
            labels.append(curr_label)
            images, labels = shuffle(images, labels)

            output.append((images, labels))
return output

(X_train, y_train), (X_test, y_test) = data_load()

----> 1 (X_train, y_train), (X_test, y_test) = data_load()

ValueError: too many values to unpack (expected 2)

Answer 1

就这么做

x,y=data_load()

然后访问 x[0],x[1] 或以您的方式
