log_str means the logs displayed in the terminal or logs dumped into xxx.log. As described in #916, we want to see memory information in the saved JSON file, Tensorboard or WandB, therefore we should add memory filed to tag, rather than extend the log_str

Hi, you can modify the following lines

mmengine/mmengine/runner/log_processor.py

Lines 199 to 200 in b1b1f53

	if is_cuda_available():
	log_str += f'memory: {self._get_max_memory(runner)} '

to

        if is_cuda_available():
            max_memory = self._get_max_memory(runner)
            log_str += f'memory: {max_memory}  '
            tag['memory'] = max_memory
