The link to TensorFlow Jenkins continuous integration site (http://ci.tensorflow.org/view/Nightly/job/nightly-pi/223/artifact/output-artifacts) is broken. The same is in the blog-post by Pete Warden that follows in the book (https://petewarden.com/2017/08/20/cross-compiling-tensorflow-for-the-raspberrypi). What is the replacement for these links?
