Hi, I have a few questions about the dimensions in yourt code.
Is your input dimension format like B C H W, eg, 1, 3, 224, 224?
If so, I suppose the dim in layernorm you initialized is C. when I run this, I got an error like
Given normalized_shape=[2304], expected input with shape [*, 2304], but got input of size[8, 2304, 8, 8]
And also, how do you get the shape of nW*B, window_size*window_size, C
after axis shift?
Thank you
Thank you for your work!
However, I did not find your code for semantic segmentation. I am currently working on pure-MLP segmentation and it would be a huge help if you could provide the ASMLP code for semantic segmentation.
The CUDA kernel of basic op seems to be borrowed from https://github.com/d-li14/involution, especially implied by https://github.com/svip-lab/AS-MLP/blob/main/models/shift_cuda.py#L169.
Please consider properly giving credit to the involution repo and citing us. Thanks.

Thanks for sharing your work!
Why did you design PathMerging Layer normalizing features first?
I think that if we normalize features after reduce layer, we can reduce the size of model and flops.
Did you do ablation study for this layer?
For example,
class PatchMerging(nn.Module):
r""" Patch Merging Layer.
Args:
input_resolution (tuple[int]): Resolution of input feature.
dim (int): Number of input channels.
norm_layer (nn.Module, optional): Normalization layer. Default: nn.LayerNorm
"""
def __init__(self, input_resolution, dim, norm_layer=nn.LayerNorm):
super().__init__()
self.input_resolution = input_resolution
self.dim = dim
self.reduction = nn.Conv2d(4 * dim, 2 * dim, 1, 1, bias=False)
self.norm = norm_layer(2 * dim)
def forward(self, x):
"""
x: B, H*W, C
"""
B, C, H, W = x.shape
#assert L == H * W, "input feature has wrong size"
assert H % 2 == 0 and W % 2 == 0, f"x size ({H}*{W}) are not even."
x = x.view(B, C, H, W)
x0 = x[:, :, 0::2, 0::2] # B C H/2 W/2
x1 = x[:, :, 1::2, 0::2] # B C H/2 W/2
x2 = x[:, :, 0::2, 1::2] # B C H/2 W/2
x3 = x[:, :, 1::2, 1::2] # B C H/2 W/2
x = torch.cat([x0, x1, x2, x3], 1) # B 4*C H/2 W/2
x = self.reduction(x)
x = self.norm(x)
return x
I arrived this repo via followings' likes. For those who like me, it would be good if paper link is included in README.
Anyway, thanks for your great effort and reports.

运行test.sh显示Error while finding module specification for 'torch.distributed.launch'但是我terminal中是有torch的包的 这个分布式训练是否还需要在config文件中做修改,cuda11.0版本
Thanks for sharing such a simple yet effective backbone work~
When I run the code, I find no noticeable runtime difference between using the shift_cuda.py and using Algorithm 1 in the paper with Pytorch itself.
Do I miss something to activate the CUDA acceleration?
In fact, I copy part of the core codes in this repo and integrate the codes to the Swin Transformer, instead of running this repo directly.
Could you please help me with this problem? Thanks~
cuda11 apex换成另外一个版本的可以跑吗
Like many projects, they would provide torch cuda extensions and a setup.py
to compile and generate .so
file so that they can be loaded and used. Could you provide such method to use as_shift op?
It seems that the code cannot generate "./train_pkl/samples_bytes_0.pkl" successfully.
The first running, generate pkl, but return error:

Hello! Thank you for your wonderful job!
it is said that as-mlp uses the same training strategy in Swin Transformer, I want to know to what extend the work use the same strategy ? For example, does as-mlp use Mixup、Cutmix?
I saw there exists codes for mixup in function build_loader which requires config.AUG.MIXUP, but I didn't find config.AUG in the config file for models.
I want to know the detailed training setting for your models, may you do the favor for me?
Hello, thanks for sharing your work. We have tride the code on AS-MLP-T, and only get 81.13/81.06 in two seperate experiments. Are there any settings needed to be modified?
