samskalicky edited a comment on issue #13976: Problem of exporting FP16 SyncBN model. URL: https://github.com/apache/incubator-mxnet/issues/13976#issuecomment-458280830 Hi @Fiend1213 The current implementation of Synchronized Batch Normalization (SyncBN) does not support FP16 training. Since you're use-case is just for inference, SyncBN has exactly the same behavior as BN during inference. Therefore, just replace SyncBN with regular nn.BatchNorm to resolve your problem. Please reply if this resolves your issue.
