Even our biological neural networks implemented throughout our visual cortex seem to have some difficulty finding the leopard in each image, at first glance. Let's see how well its artificial counterpart does at this the task. In the following segment of code, we import the saliency visualizer object from the keras-vis module, as well as a utils tool that lets us search for layers by name. Note that this module does not come with the standard Keras install. However, it can be easily installed using the pip package manager on Python. You can even execute the install through your Jupyter environment:
! pip install keras-vis
