Training time estimation when max_epochs is given

[HansBambel]

🚀 Feature

Time estimation of training until max_epochs are reached.

Motivation

Right now I don't see how long I am training for already and how long it is going to take to train e.g. 500 epochs.
I usually have a tqdm progress bar for number of epochs to get an estimate how long my training will run maximally.

Pitch

If max_epochs is given, create a tqdm progress bar (probably with leave=True).

Alternatives

Keep it like it is and make rough estimations per hand.

Hi! thanks for your contribution!, great first issue!

[williamFalcon]

? we already have a tqdm bar. in case you need a custom one you can also implement one using a callback @awaelchli

[HansBambel]

I know, but it only shows the time for the current epoch, but not how long the overall training will take.

[williamFalcon]

don't you just multiply times the num of epochs?

[HansBambel]

Then I would not have a time for how long I am training already and I would need to manually check how long one epoch takes and do the calculation manually.

Such a feature was mentioned in #765 and #1450 as well. There it was called global progress bar. That's what I meant. Sorry for the confusion.

[awaelchli]

Maybe we could provide such a global progress bar as part of bolts.

its 2024, this issue hasnt been fixed? we need to see estimated time for training and how long training has been running on the progress bar
