How to use the test function from the trainer?

❓ Questions and Help

What is your question?

So when I test my model with trainer.test() I get as output this:

 ----------------------------------------------------------------------------------------------------
TEST RESULTS
{}
----------------------------------------------------------------------------------------------------

I suppose in the empty bracket can stand sth. But I dont know what can stand there and where to do it. I can’t seem to find it in the docs not under trainer nor under test set stands for what this is. If I am right and it doesn’T stand anywhere maybe add to the docs.

Code

trainer.test()

What have you tried?

Searching the docs and google it.

What’s your environment?

• Windows 10
• conda
• lighning 0.7.1

I would like to vote for reopening this issue, the solution is too dark right now. I think pytorch lightning has a lot of potential. A better solution is needed

I would like to vote for reopening this issue, in particular because the Introduction Guide suggests that any value returned in the dictionary in test_epoch_end will be displayed in the summary. I assume that this was the case in the past, and that the Introduction Guide is simply outdated in this regard. Nevertheless, having to wrap it in a key called progress_bar seems counter-intuitive.

More generally speaking, it would help if there was a centralised documentation on what keys to return in the dictionary in each of these functions 😃.

And of course, thanks so much for the work on this library. I’m just exploring it right now, but it looks really nice to use 😃. I’m quite excited!
