visualize_cam is working but visualize_saliency, visualize_activation are not!

[Avcu]

I can use visualize_cam without any problem but I get the following error for the _saliency and _activation methods.
Error:

I have also tried the template code on github and got the same error. By the way, I have installed the keras-vis few days ago I don't think I am using an older version.

Hi, everyone this issue literally takes my two days since I'm quite new to the python&keras&tf despite having some coding background. For the time being just downgrade your tensorflow to the 1.7.1 if you're using the last verified one which is 1.8.0.
So, I'm closing this issue and creating new one about the versions.
