hi, i success installed the modules in the README.

when i try to run the main.py i got exceptions below: No module named 'ignite.metrics' No module named 'ignite.exceptions'

these two attribute also don't exist in the source code in the ignite module.

Hi @fooSynaptic, thank you for your interest in this project.

When I authored this code in April 2018 the ignite library did not have any releases yet and it was on commit 2304e5eaaf4e0face17ce5256aac7544a26fab27. If you check out that commit and run this code it should work.

The long term, proper fix is for me to upgrade the code to use the latest API.
