mmcls.models.ConvMixer¶

class mmcls.models.ConvMixer(arch='768/32', in_channels=3, norm_cfg={'type': 'BN'}, act_cfg={'type': 'GELU'}, out_indices=- 1, frozen_stages=0, init_cfg=None)[源代码]¶

ConvMixer. .

A PyTorch implementation of : Patches Are All You Need?

Modified from the official repo and timm.

参数

arch (str | dict) –
The model’s architecture. If string, it should be one of architecture in ConvMixer.arch_settings. And if dict, it should include the following two keys:
- embed_dims (int): The dimensions of patch embedding.
- depth (int): Number of repetitions of ConvMixer Layer.
- patch_size (int): The patch size.
- kernel_size (int): The kernel size of depthwise conv layers.
Defaults to ‘768/32’.
in_channels (int) – Number of input image channels. Defaults to 3.
patch_size (int) – The size of one patch in the patch embed layer. Defaults to 7.
norm_cfg (dict) – The config dict for norm layers. Defaults to dict(type='BN').
act_cfg (dict) – The config dict for activation after each convolution. Defaults to dict(type='GELU').
out_indices (Sequence | int) – Output from which stages. Defaults to -1, means the last stage.
frozen_stages (int) – Stages to be frozen (all param fixed). Defaults to 0, which means not freezing any parameters.
init_cfg (dict, optional) – Initialization config dict.
