Error in Image Explanation

[kimhs950627]

It seems that when trying the explain function with keras cnn models, following error occurs:
"Type error : expected str, bytes or os.pathlike object not list".
I tried explanation with custom models and vgg16 model. It seems that the file path I tried ty explain tossed to the load_img in the keras-preprocessing module as an "list" not an character or file.path() result.
Can anybody help?? :(...
