导入错误:无法导入 PIL.图像.使用“array_to_img”需要 PIL

Question

这非常棘手。我几乎已经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__)

一切似乎都很好，系统将打印

但是在我的编码中，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

错误将如下所示：

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。
