Could you please provide more details about your problem, like your train platform info and a full error log?

We are planning this model indeed. However, it won't be finished in a short time due to the lack of developers. Collaborations are appreciated If you are interested in it.

would you like to provide the total error log? In fact, currently we don't know where the error is caused

If you don't mind, would you like to provide the full error log?

I have a little question about your `img_norm_cfg`. If you don't mind, would you like to tell us why to use this `img_norm_cfg` ``` img_norm_cfg = dict(mean=[0,0,0], std=[1,1,1], to_rgb=True) ```

I have checked the config file of voc dataset, but I found the path for the test dataset. https://github.com/open-mmlab/mmsegmentation/blob/5c113d98ecf362d9a215fbb3016ea7e76850ed98/configs/_base_/datasets/pascal_voc12.py#L44-L57

Might check the cfg with the below code: ``` from mmcv.utils import Config cfg = Config.fromfile('cfg_file') print(cfg.data.test.ann_dir) ``` Besides, based on my limited knowledge, I think `Not implementedError` might occur...
