   > Set Rank and Barrier in forward and backward as separate variables won't resolve the deadlock issue. I suggest instead we postfix their key parameter with "forward" and "backward".
   
   Hello, @RogerChern. I also met a deadlock issue while [training PSPNet on `gluon-cv`](https://github.com/dmlc/gluon-cv/blob/master/scripts/segmentation/train.py). For the "key parameter" you mentioned above, do you mean [the one in this line](https://github.com/apache/incubator-mxnet/blob/c93c78e6459eb55ddba65b5564db366e612733f8/python/mxnet/gluon/contrib/nn/basic_layers.py#L225)? Could you please share more details about the fix? Thank you.
