Hi visioner,
It won't work on pseudo distributed because you need to run at least 2 NN and if you run 2NN
then u need to configure them separately on different ports. It's little tricky doing on one
node. Multiple VM is the cleanest solution.

Best Regards,

directories and port numbers. If you want to just give it a try, it is easier to spawn 3 VMs
and use them as separate nodes.
