在使用函数时显示NameError: name 'skimage' is not defined

Question

from pathlib import Path

from sklearn import svm, metrics, datasets
from sklearn.utils import Bunch
from sklearn.model_selection import  train_test_split
from skimage.io import imread# abc

    image_dir = Path(container_path)
    folders = [directory for directory in image_dir.iterdir() if directory.is_dir()]
    categories = [fo.name for fo in folders]

    descr = "A image classification dataset"

    for i, direc in enumerate(folders):

    return Bunch(data=flat_data,

                 images=images,
                 DESCR=descr)

image_dataset = load_image_files("G:\images")

你 from skimage.io import imread 是直接引入了imread函数

要

img = imread(file)

这样调用
