Tensorflow with_dependencies is now deprecated (and results in errors)

[DanielTakeshi]

Thanks for a great guide to debugging! I was using the assertions code you wrote. However, note that tf.with_dependencies is now deprecated and results in errors when used.

The alternative, as shown in this StackOverflow post, is what you already had, so that's good. I just recommend in slide 39 to remove the tf.with_dependencies part entirely.
