In version 1.1.6, when using 2 GPUs and MMDataparallel non-distributed training DeepLabV3+R-101-D8 769x769 80000+cityscapes
Modify line 68 of mmseg/apis/train.py:

model = MMDataParallel(
           model.cuda(cfg.gpu_ids[0]), device_ids=cfg.gpu_ids)

to

model = MMDataParallel(
            model.cuda(), device_ids=cfg.gpu_ids)

the GPU usage is as follows:

1

It seems that the GPU 1 has not loaded the data. What is the reason?Is it related to the train_step() function？
