Dilated ResNet in SFNet?
wondervictor opened this issue · 4 comments
Hi, I find that the SFNet w/ ResNet-18 has adopt dilated convolutions in C4 and C5:
SFSegNets/network/sfnet_resnet.py
Line 202 in 773c7b7
However, it hasn't been mentioned in the paper or the other implementation torchcv.
I'm confused about it.
@wondervictor Hi! Thanks for your remind. Note that this is re-implementation of our SFnet which achieve better reasuts than paper. You can turn the dilation off. I remember it only drop a little after longer training.
Hi @lxtGH, I found another setting was strange to me.
see:
SFSegNets/network/sfnet_resnet.py
Line 53 in ce97d2e
and
SFSegNets/network/sfnet_resnet.py
Line 79 in ce97d2e
The normalization layers in
fpn_out
and conv_last
are nn.BatchNorm2d
but not SyncBatchNorm
due to unspecific parameter normal_layer
for function conv3x3_bn_relu
.I'm concerned about whether it is a special setting or a bug.
It may be a bug but it seems that it dose not effect the performance.
Time to close this issue. If you have more question. please re-open it.
