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

from pathlib import Path
import matplotlib.pyplot as plt
import numpy as np
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
from skimage.transform import resize


def load_image_files(container_path, dimension=(64, 64)):  
    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"
    images = []
    flat_data = []
    target = []
    for i, direc in enumerate(folders):
        for file in direc.iterdir():
            img = skimage.io.imread(file)
            img_resized = resize(img, dimension, anti_aliasing=True, mode='reflect')
            flat_data.append(img_resized.flatten()) 
            images.append(img_resized)
            target.append(i)
    flat_data = np.array(flat_data)
    target = np.array(target)
    images = np.array(images)

    return Bunch(data=flat_data,
                 target=target,
                 target_names=categories,
                 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

代码中导入库和调用库函数不对应导致的错误。如果代码用img = skimage.io.imread(file)读取图片数据的话，则要用import skimage.io，如用from skimage.io import imread导入的话，调用就要改成img = imread(file)，还可用from skimage import io,对应 img=io.imread(file)
