ImportError：无法导入PIL.Image。使用load_img需要PIL

Question

当我从独立单元格中的PIL导入映像运行时，我正在使用PIL库，但它运行正常，但是在执行该操作时，我在下面收到错误消息。

ImportError                               Traceback (most recent call last)

----> 8     img = tensorflow.keras.preprocessing.image.load_img(image_path, target_size=(HEIGHT, WIDTH))
      9     encoding_train[id] = encodeImage(img)
     10   with open(train_path, "wb") as fp:
