MobileNetV3 backbone.

Parameters:

arch (str) – Architecture of mobilnetv3, from {small, large}. Default: small.
conv_cfg (dict, optional) – Config dict for convolution layer. Default: None, which means using conv2d.
norm_cfg (dict) – Config dict for normalization layer. Default: dict(type=’BN’).
out_indices (None or Sequence[int]) – Output from which stages. Default: None, which means output tensors from final stage.
frozen_stages (int) – Stages to be frozen (all param fixed). Default: -1, which means not freezing any parameters.
norm_eval (bool) – Whether to set norm layers to eval mode, namely, freeze running stats (mean and var). Note: Effect on Batch Norm and its variants only. Default: False.
with_cp (bool) – Use checkpoint or not. Using checkpoint will save some memory while slowing down the training speed. Default: False.
