Do you use Synchronized Batch normalization? #23

Closed acgtyrant closed 6 years ago

acgtyrant commented 6 years ago

If so, does your open MXNet support it?

Lyken17 commented 6 years ago

To my best knowledge, MXNet hasn't supported synchronized Batch Normalization yet. So the same as this project.

Unlike PSP, even without synchronized batch normalization, it is easy to reproduce DUC with meanIoU of 80.2 on cityscape dataset.

If you do want avoid the affect of unsynchronized batch normalization, a simple trick is to reduce the image size and increase the batch size. (Or purchase more fancy GPUs

Synchonized Batch Normalization is currently not supported by MxNet.
