[feature request] Add visualization support of model training

[Newtype07]

Hello,

In TensorFlow for R, they implement a visualization tool tensorboard.R, which enables real-time visualization of training process in viewer of RStudio. Adding a similar tool in torch for R is a great idea.

That would be nice! We have implmented tensorboard support with https://github.com/mlverse/tfevents. Thus if you point tensorboard to a log directory you'll be able to see live training metrics.

That's also possible if you use guildai for your experiments.

We still need to write docs on all this, but let us know if you try it.
