Metrics computation during the training about ignite

[alykhantejani]

Hi @vfdev-5,

I plan to have metric computation available as handlers (probably under ignite.handlers.metrics) which users can then attach to events.

These can take a logger argument, which could default to print but the user can pass in my_logger.info instead for example and the handler will just call logger(result)

As always PRs are welcome :)

@vfdev-5 some basic metrics have now been merged. Please open an issue for any specific metric request you may have

Hi,
I am newbie in pythorch. Is there a simple example that uses some metrics?
Thanks

[vfdev-5]

@sjsy, yes, see here, for example.

@vfdev-5 , in the example you pointed out, the metrics are attached to create_supervised_evaluator. How can I attach some metrics to create_supervised_trainer? So I can investigate training progress by attached metrics as well as the loss.
Thanks.

@sjsy actually, you can do it like this and this. HTH
