mlp-mixer-pytorch
PyTorch implementation of "MLP-Mixer: An all-MLP Architecture for Vision" Tolstikhin et al. (2021)
Usage
import torch
from mlp_mixer import MLPMixer
model = MLPMixer(
num_classes = 10,
num_layers = 8,
image_size = 256,
patch_size = 32,
channels = 3,
hidden_dim = 512,
tokens_hidden_dim = 256,
channels_hidden_dim = 2048
)
x = torch.randn(1, 3, 256, 256)
model(x) # (1, 10)
Preconfigured models
