Hi @ericspod @wyli @vfdev-5 ,

I feel maybe it's better to change the _iteration() function of engines to be a staticmethod or classmethod:
https://github.com/Project-MONAI/MONAI/blob/dev/monai/engines/trainer.py#L164
I have 2 reasons:

Currently, the self and the engine args in this function mean the same thing, some of the code uses self.XXX, some of the code uses engine.XXX. No need the self arg at all.
If users want to pass their own iteration logic to the engine, it will be a regular function without self arg, users may need to refer to our default implementation.

Another thing: I want to change all the typehints engine: Engine to engine: Workflow, because actually our engine functions only work with MONAI engine workflows and ignite Engine type caused many mypy errors.

What do you think?

Thanks in advance.

Hi @ericspod ,

What do you think about these 2 points? If you don't have concerns, I will do it in a seperate PR in case we may revert..

Thanks in advance.

ericspod · 2022-04-19T13:09:14Z

The value of _iteration being a regular method is to allow override in subclasses easily. This could be done with classmethod as well but it's a slightly more complex mechanism that is a bit confusing to less advanced Python users, explaining the difference between staticmethod and classmethod can be difficult. I don't think staticmethod should really be used anyway since we can define functions outside classes, unlike pure OO languages.

For using self or engine I would normally want to use self to make it clear we're using the current object, even if the reader forgets that the engine argument and self are the same they'll be directed away from using the argument. However if anyone wants to define their own function rather than override the method it's easier to copy-paste code that doesn't reference self, so I'd go with engine.

Changing the type hint to Workflow is probably the right change now if we've totally broken compatibility with the original Engine class.

Nic-Ma · 2022-04-19T14:56:30Z

Hi @ericspod ,

Thanks very much for your detailed analysis and comments.
How about doing below changes in a separate PR:

Still defining _iteration() as a regular method, but unify all the self.XXX and engine.XXX to engine.XXX. Because (1) as you said users can easily copy-paste our code, (2) maybe someone will override the engine run logic someday and pass other engine as parameter instead of self: https://github.com/pytorch/ignite/blob/master/ignite/engine/engine.py#L859.
Check all the engine: Engine functions, if having MONAI specific logic, change the typehint to Workflow.

What do you think?
And this PR is only for the AMP parameters according to user's feedback, ready for review.

Thanks in advance.

Sounds good to me. I'll approve here but we should work out what the failures are about, there's not error output.

Hi @ericspod ,

Thanks for your review.
The failure is because Github changed CI authentication policy this week and our remote machine is offline and need to sign in again (@IsaacYangSLA or @wyli may know more). But currently, we mainly use the blossom CI environment, so the Github CI is just optional tests, we can merge PRs once blossom tests passed.

Thanks.
