## Motivation Support `MMSegInferencer` for providing an easy and clean interface for single or multiple images inferencing. Ref: https://github.com/open-mmlab/mmengine/pull/773 https://github.com/open-mmlab/mmocr/pull/1608 ## Modification - mmseg/apis/mmseg_inferencer.py - mmseg/visualization/local_visualizer.py - demo/image_demo_with_inferencer.py ## Use cases (Optional) Based on https://github.com/open-mmlab/mmengine/tree/inference Add a new image inference demo with `MMSegInferencer` - demo/image_demo_with_inferencer.py ```shell python demo/image_demo_with_inferencer.py demo/demo.png fcn_r50-d8_4xb2-40k_cityscapes-512x1024 ``` --------- Co-authored-by: MeowZheng <meowzheng@outlook.com>
