I liked how Gunnar wrote pretty much all of the code on the fly as we were going through, but that there was plenty of pre-prepared material on the google drive that I can refer to after the training. The code Gunnar wrote based on the sample data I provided beforehand was also extremely useful and also made the training relevant to our own datasets.
