samskalicky commented 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.
