Description

🚀 Feature

The idea is to provide a debug mode as discussed here: https://github.com/pytorch/ignite/issues/1989#issuecomment-833643158.

All the possible options can be discussed here. We could add an helper to track the workflow of handlers from the engine run. On the other hand, some specific debug tools are needed to track the values of PyTorch objects (LR, loss, grads, etc.). Note that the preferred way to extend ignite is handlers' design so let's create a new set of tools for the debugging.

Contributor guide

Research direction
Review the existing handler based architecture in Ignite and investigate how a debug mode could integrate with the Engine run loop. Examine the discussion thread for concrete requirements and prior art. Propose a design for tracking handler execution and optionally PyTorch object values.
