Hi @MengzhangLI
Please review this PR and give some comments.

This enhancement could be ran correctly.

But the metric of all logs should keep the same, otherwise, the error may happens.

For example, if metric of log.json files have mDice and mIoU at the same time, but the input is mDice, then error may be raised during handling certain log.json file whose metric is mIoU.

However, if all .log.json files have same metric, it could run correctly.
