LGTM, just would be nice to have tests for uncovered lines...

@Borda ok, I will try to make it higher

Thank you so much for implementing this!

@awaelchli I love this feature! I left some minor suggestions on typing and docs, so would you mind having a look at them? They should be resolved by clicking some buttons in your browser :]

Hey @awaelchli, why not push it directly to PL ?

awaelchli · 2021-01-09T17:36:30Z

Because @williamFalcon wants only essential callbacks in core PL library, and all non-essential, specialized callbacks here in bolts. Or at least this the information I have back from when pl_bolts was created, maybe it changed. I do not want to force this into any library unless team/community wants it.

This looks like a great feature and we need to provide more callback examples to people.

It is up to you, but I see its value for PL.

Thank you for the kind feedback. Ok, let me adress the remaining review comments here on the PR and I will double check with William.

+        self.model = model

+    def check(self, *args: Any, **kwargs: Any) -> bool:


@akihironitta this mypy tool is not very smart :( It is not liking that the subclass has different args than here. I want this abstract method to be as general as possible and not specify concrete arguments and types. It should only act as an interface. Any suggestions how to proceed? I believe I have to add # type: ignore

I found a related issue in mypy repo, and it basically says that an easy workaround would be to add # type: ignore[override], so shall we just ignore it then?
python/mypy#1237 (comment)

no chance, it won't work. I tried to put it everywhere: at the top of method, on the same line as signature, below it, on top of the class, on top of the file, both in subclass and superclass.

I had to spam #type: ignore everywhere to make it work.
This mypy tool, I don't understand it. I spent hours now studying the docs of this tool trying to figure out what the error messages mean. I tried everything, but the type: ignore are unavoidable, yet they pollute the code unnecessarily. It's unbelievably frustrating, and I can no longer work on this, sorry.

I completely understand your frustration. Let's ignore them all for now.
