ResNetV1d

class mmpretrain.models.backbones.ResNetV1d(**kwargs)

ResNetV1d backbone.

This variant is described in Bag of Tricks..

Compared with default ResNet(ResNetV1b), ResNetV1d replaces the 7x7 conv in the input stem with three 3x3 convs. And in the downsampling block, a 2x2 avg_pool with stride 2 is added before conv, whose stride is changed to 1.
