WebWhen we build a norm layer with `build_norm_layer ()`, we want to preserve the norm type in variable names, e.g, self.bn1, self.gn. This method will infer the abbreviation to map class types to abbreviations. Rule 1: If the class has the property "_abbr_", return the property. Rule 2: If the parent class is _BatchNorm, GroupNorm, LayerNorm or ...

Web3.1 forward. 复习一下方差的计算方式： \sigma^2=\frac {1} {m}\sum_ {i=1}^m (x_i - \mu)^2. 单卡上的 BN 会计算该卡对应输入的均值、方差，然后做 Normalize；SyncBN 则需要得 … WebFor SyncBatchNorm, we support two sources: Apex and PyTorch. The optimized SyncBN kernels provided by apex run faster. Parameters. config – configuration file. model – Pytorch model whose BatchNorm layers should be converted to SyncBN layers. NOTE: Since SyncBatchNorm layer synchronize the BN stats across machines, using Webapex.parallel.SyncBatchNorm is designed to work with DistributedDataParallel. When running in training mode, the layer reduces stats across all processes to increase the effective batchsize for normalization layer. This is useful in applications where batch size is small on a given process that would diminish converged accuracy of the model. javascript print image from url
