python ndim函数_Python列表函数ndim和大小

我停留在这一点上的代码，其中代码是指打印使用NDIM和大小列表的大小和尺寸。我收到一个错误“list object has no attribute ndim。”

`进口OS

import skimage

import pdb

from skimage import data

ROOT_PATH = "/tmp/"

train_data_directory =os.path.join(ROOT_PATH,

\mozilla_vijaya0/Training")

test_data_directory = os.path.join(ROOT_PATH,

"mozilla_vijaya0/Testing")

def load_data(data_directory):

directories = [d for d in os.listdir(data_directory)

if os.path.isdir(os.path.join(data_directory, d))]

labels = []

images = []

for d in directories:

label_directory = os.path.join(data_directory, d)

file_names = [os.path.join(label_directory, f)

for f in os.listdir(label_directory)

if f.endswith(".ppm")]

for f in file_names:

images.append(skimage.data.imread(f))

labels.append(int(d))

return images, labels

images, labels = load_data(train_data_directory)

print(images.ndim)

print(images.size)

images[0]`

什么是显示列表的尺寸和大小的正确途径。
