ImportError：无法导入 PIL.Image。 `array_to_img`的使用需要PIL

Question

这非常棘手。我几乎尝试了互联网上的所有解决方案，但仍然无法解决这个问题。

如果我只是输入

from PIL import ImageFile
print(Image.__file__)

一切正常，系统将打印

C:\Users\BenWang\Anaconda3\envs\tensorflow\lib\site-packages\PIL\Image.py

这样

但在我的编码中，如果我使用以下代码：

import sys
from PIL import Image
ImageFile.LOAD_TRUNCATED_IMAGES = True                 

train_tensors = paths_to_tensor(train_files).astype('float32')/255
valid_tensors = paths_to_tensor(valid_files).astype('float32')/255
test_tensors = paths_to_tensor(test_files).astype('float32')/255

错误将显示如下：

    104     img = pil_image.open(path)

ImportError: Could not import PIL.Image. The use of `array_to_img` requires PIL.

我只是遇到了这样的问题。然后我安装枕头并重新启动内核（Spyder）来解决它。
