python-matplotlib IndexError：列表索引超出范围[关闭]

我无法理解我写错了什么。我尝试将值从 1 更改为 0 或 2，但没有帮助。my_dataset 用于存储数据和目标值

my_dataset = []
for image_file in glob.glob('my_image/_my_?.png'):
    label_y = int(image_file[-5:-4])
    image_list = scipy.misc.imread(image_file, flatten=True)
    image_data  = 255.0 - image_list.reshape(784)

    my_data = np.append(label_y, image_data)
    my_dataset.append(my_data)


room_choices = 0
matplotlib.pyplot.imshow(my_dataset[room_choices][1:].reshape(28,28)) 
IndexError                                Traceback (most recent call last)
/var/folders/7x/q0gw9knx0klf7ngkgvd95wj40000gn/T/ipykernel_62654/3212784161.py in <module>
      1 room_choices = 0
----> 2 matplotlib.pyplot.imshow(my_dataset[room_choices][1:].reshape(28,28), cmap='Greys', interpolation='None')
      3 correct_label = my_dataset[room_choices][0]
      4 
      5 input_x = my_dataset[room_choices][1:]

IndexError: list index out of range

期望的答案：
