ngunauj opened a new issue #15665: syncbatchnorm0_gamma' has not been initialized yet because initialization was deferred URL: https://github.com/apache/incubator-mxnet/issues/15665 The part of forward.. ``` def forward(self, x): x = self.conv1(x) x = self.bn1(x) x = self.relu(x) x = self.conv2(x) x = self.bn2(x) x = self.relu(x) ``` The part of define.. ``` self.conv1 = nn.Conv2D( channels=64, kernel_size=3, strides=2, padding=1, in_channels=3, use_bias=False) self.bn1 = BatchNorm2d(in_channels=64, momentum=BN_MOMENTUM) self.conv2 = nn.Conv2D( channels=64, kernel_size=3, strides=2, padding=1, in_channels=64, use_bias=False) self.bn2 = BatchNorm2d(in_channels=64, momentum=BN_MOMENTUM) self.relu = nn.Activation('relu') ``` the BatchNorm2d is ``` from mxnet.gluon.contrib.nn import SyncBatchNorm BatchNorm2d = functools.partial(SyncBatchNorm, num_devices=4) ``` when run the cod, the error is `syncbatchnorm0_gamma' has not been initialized yet because initialization was deferred`. when i change the SyncBatchNorm to BatchNorm is ok....
