Basically, on 0.14 > the script took longer to run and had 2513 Spark instructions executed, while > on 0.13 only 864 Spark instructions were executed. This was run locally on a > laptop using the 2 instructions at the top of the script (and copied below). > I've also attached the stats and runtime explain logs. > 1. Download data > {code} > nn/examples/get_mnist_data.sh > {code} > 2.
