Another profiling tool is already active

[zhaohm14]

Bug description

When I try to use profiler='advanced' when creating a trainer, this error will be raised inside trainer.fit():

ValueError: Another profiling tool is already active

It will be ok if use profiler='simple'

What version are you seeing the problem on?

master

How to reproduce the bug

trainer = L.Trainer(
        default_root_dir=config.train.save_dir,
        callbacks=[
            ModelCheckpoint(
                dirpath=config.train.save_dir,
                every_n_train_steps=config.train.save_step,
                save_top_k=config.train.save_ckpt_keep_num,
                mode='max',
                monitor='global_step'
            ),
            ModelSummary(max_depth=9)
        ],
        logger=WandbLogger(log_model="all"),
        **config.train.trainer
    )
    if config.train.resume_from_ckpt:
        trainer.fit(
            model=model,
            train_dataloaders=train_loader,  # TODO: dose dataloader needed?
            val_dataloaders=val_loader,
            ckpt_path=config.train.resume_from_ckpt
        )
    else:
        trainer.fit(
            model=model,
            train_dataloaders=train_loader,
            val_dataloaders=val_loader
        )

The explanation for why this happens is here: python/cpython#110770 (comment)

The AdvancedProfiler in Lightning enables multiple profilers in a nested fashion, which is apparently not supported by Python but so far was not complaining, until Python 3.12. To resolve this, the AdvancedProfiler will have to be reworked somehow. So there is some work needed here.

Thanks a lot for your help!

I'd like to keep the issue open, because we need to work on this (help from community appreciated).
