Overview

Deformable Attention

Implementation of Deformable Attention from this paper in Pytorch, which appears to be an improvement to what was proposed in DETR. The relative positional embedding has also been modified for better extrapolation, using the Continuous Positional Embedding proposed in SwinV2.

Install

$ pip install deformable-attention

Usage

import torch
from deformable_attention import DeformableAttention

attn = DeformableAttention(
    dim = 512,                   # feature dimensions
    dim_head = 64,               # dimension per head
    heads = 8,                   # attention heads
    dropout = 0.,                # dropout
    downsample_factor = 4,       # downsample factor (r in paper)
    offset_scale = 4,            # scale of offset, maximum offset
    offset_groups = None,        # number of offset groups, should be multiple of heads
    offset_kernel_size = 6,      # offset kernel size
)

x = torch.randn(1, 512, 64, 64)
attn(x) # (1, 512, 64, 64)

3d deformable attention

import torch
from deformable_attention import DeformableAttention3D

attn = DeformableAttention3D(
    dim = 512,                          # feature dimensions
    dim_head = 64,                      # dimension per head
    heads = 8,                          # attention heads
    dropout = 0.,                       # dropout
    downsample_factor = (2, 8, 8),      # downsample factor (r in paper)
    offset_scale = (2, 8, 8),           # scale of offset, maximum offset
    offset_kernel_size = (4, 10, 10),   # offset kernel size
)

x = torch.randn(1, 512, 10, 32, 32) # (batch, dimension, frames, height, width)
attn(x) # (1, 512, 10, 32, 32)

1d deformable attention for good measure

import torch
from deformable_attention import DeformableAttention1D

attn = DeformableAttention1D(
    dim = 128,
    downsample_factor = 4,
    offset_scale = 2,
    offset_kernel_size = 6
)

x = torch.randn(1, 128, 512)
attn(x) # (1, 128, 512)

  • The relationship between 'dim' and 'inner_dim'

    The relationship between 'dim' and 'inner_dim'

    Hi, I have a question about DeformableAttention module,

    I calculated the output volumes of the forward processes step by step, According to my calculation, the code works only when 'dim' and 'inner_dim' is same.

    Is there any reason why you implement it this way?

    Best regards, Hankyu
