resume卡住 about mmsegmentation

[chtzs]

After checking source code of mmengine, I found that they just called next to skip training data:
in mmenging\runner\loops.py IterBasedTrainLoop

        if self._iter > 0:
            print_log(
                f'Advance dataloader {self._iter} steps to skip data '
                'that has already been trained',
                logger='current',
                level=logging.WARNING)
            for _ in range(self._iter):
                next(self.dataloader_iterator)

In other words, "-- resume" will load data like regular training, but discard all of this data before reaching the specified iteration. Therefore, the time required for resuming will not be much faster than starting a new training session.

I discovered that using a lower version of mmengine helps resolve the issue. For example:

mim install mmengine==0.10.2

I think this is the cause of the problem. Here's the PR. open-mmlab/mmengine#1471
