How to change the network

[xqh-code]

@dbolyaI want to modify the network structure, I didn't find where to do it, it prints out net: YOLACT before 'net': Yolact(
(backbone): ResNetBackbone(
(layers): ModuleList(
(0): Sequential(
(0): Bottleneck(
(conv1): Conv2d(64, 64, kernel_size=(1, 1), stride=(1, 1), bias=False)
(bn1): BatchNorm2d(64, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True)
(conv2): Conv2d(64, 64, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1), bias=False)
With this structure, how can I similarly change the values here to achieve the result I want?
