导入错误：无法导入 PIL.Image。使用`load_img`需要PIL。即使使用枕头库之后

Question

我的程序是图像处理程序的特征提取，我们正在加载模型并从每个图像中提取特征。

• 我们从文件加载图像
• 将图像的像素转换为 numpy 数组
• 提取特征
• 店铺特色
• 保存到文件(pkl)

这是代码片段。

from os import listdir
from pickle import dump
from keras.applications.inception_v3 import InceptionV3
from keras.preprocessing.image import load_img
from keras.preprocessing.image import img_to_array
from keras.applications.inception_v3 import preprocess_input
from keras.models import Model
import string
from timeit import default_timer as timer
from PIL import Image
import sys

for name in listdir(directory):
    # load an image from file
    filename = directory + '/' + name
    image = load_img(filename, target_size=(230,230))
    # convert the image pixels to a numpy array
    image = img_to_array(image)
    # reshape data for the model
    image = image.reshape((1, image.shape[0], image.shape[1], image.shape[2]))
    # prepare the image for the VGG model
    image = preprocess_input(image)
    # get features
    feature = model.predict(image, verbose=0)
    # get image id
    image_id = name.split('.')[0]
    # store feature
    features[image_id] = feature
    #print('>%s' % name)
return features

它给了我这个错误

我已经安装了pillow并将其导入到程序中，但它仍然给我同样的错误。

执行“pip install Image”即可解决您的错误，不要忘记先卸载 PIL
