-----------------------------------------
Summary: Possible regression from 0.13 -> 0.14 for MNIST LeNet
script
Key: SYSTEMML-1566
URL: https://issues.apache.org/jira/browse/SYSTEMML-1566
Project: SystemML
Issue Type: Bug
Reporter: Mike Dusenberry
Attachments: explain.txt, stats.txt
For the 0.14 release testing, I tried out the [MNIST LeNet example |
https://github.com/apache/incubator-systemml/blob/master/scripts/nn/examples/mnist_lenet-train.dml]
on both 0.13 and 0.14 and noticed a possible regression. 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. Execute from the {{scripts}} directory.
{code}
