Hi,

I cannot properly select selective_scan_cuda:
How can the error about the unresolved symbol be solved?

During the training process, the problem of loss being nan occurred. Why is this?

TypeError: init() got an unexpected keyword argument 'bimamba_type'

Any plans for uploading the weights for the vim-s model?

I have see mamba-ssm's offical page: Other requirements: Linux. so could I run it on Windows？
Here is the page：https://pypi.org/project/mamba-ssm/1.1.4/

Hi, thanks for the great work!
I encountered the following error：

I‘m wondering if conv1d_out = causal_conv1d_cuda.causal_conv1d_fwd(x, conv1d_weight, conv1d_bias,None, True) should be conv1d_out = causal_conv1d_cuda.causal_conv1d_fwd(x, conv1d_weight, conv1d_bias, True) in mamba-1p1p1/mamba_ssm/ops/selective_scan_interface.py ?

Dear authors,

THanks to your excellent work.
I would like to use Vim as backbone for downstream task, I need to load the pretraied weight on Imagenet-1K, then finetune the network on downstream-task dataset,
then, what lr_scheduler and optimizer should I use?
Could you please give me some suggestions about the super-params?

Hi,

Could you please upload code for the segmentor head? i dont see them in the codebase, while the paper clearly showed segmentation performance.

Thanks,
Michael

Hi @Unrealluver,

I saw you fused the add and norm operations in the Block class. I'm unsure of the difference between fused_add_norm=True and fused_addn_norm=False. More specifically, can I simply treat fused_add_norm_fn as a integration of following codes?

By the way, have you tried to use LN -> Mixer -> Add like a standard block does? Will it be different compared with Add -> LN -> Mixer in accuracy or speed?

I get an error. ../torch/csrc/autograd/saved_variable.cpp":216, please report a bug to PyTorch. No grad accumulator for a saved leaf.

It's thrown at mamba_ssm\ops\selective_scan_interface.py backward(ctx, dout)

(xz, conv1d_weight, conv1d_bias, x_dbl, x_proj_weight, delta_proj_weight, 
         conv1d_out, delta, A, B, C, D, delta_bias, scan_intermediates, out) = ctx.saved_tensors

Could you please give me some hints? Thank you.

what is the problem?

hi,

Since the pretrained model's head is 1000 classes, how can I test it on the CIFAR dataset which only has 100 classes?

For the coco2017 dataset, could you provide the data preprocessing code about how to construct it properly for evaluation?
here is my data folder structure for coco dataset:
-dataset
-coco
-annotations
-images
-test
-train

Inquiry Regarding Model Open Sourcing

I can't find the FLOPs in the paper. Could you please provide the flops of Vim models?

When I run "python setup.py install" in the mamba-1p1p1 folder, I get the following error:
Processing dependencies for mamba-ssm==1.1.1
Searching for zope-interface>=5
Reading https://pypi.org/simple/zope-interface/
No local packages or working download links found for zope-interface>=5
error: Could not find suitable distribution for Requirement.parse('zope-interface>=5')

However, I have installed zope-interface==5 or zope-interface==6.2 and it still gives the same error.
What is the reason for this? How can I fix it?

Can you provide a generic launch script for pre-training with vim?
The readme suggests to run:
bash vim/scripts/pt-vim-t.sh

but the contents of pt-vimt-t.sh have a bunch of local hardcoded paths that do not exist on regular servers ala:
--data-path /share/project/lianghuizhu/datasets/IN1K
source /opt/conda/bin/activate /home/zhulianghui/.conda/envs/deit-dev
etc.

Thanks very much.

Hello,

Thank you very much for the insightful work detailed in your paper!

The training recipe (e.g. learning rate, scheduler, #of epochs) and results for the Vim-T and Vim-S models were quite informative.

I am actually interested in adapting this approach for the base model. Could you provide guidance on any modifications needed in the training recipe for this purpose?

Additionally, if you might have results for the base model on ImageNet 1K, I would greatly appreciate if you could share them. This would allow me to benchmark my training outcomes against yours for a comprehensive comparison.

Thank you once again for your valuable contributions!

Hi authors,

When do you plan to release the full code?

Thanks.

Could you explain how to get the computation of SSM like your equation(8) in paper?

I try to install causal_conv1d and use the command:
pip install -e causal_conv1d>=1.1.0
but have this error:

Hi everyone, first thing first, kudos to all the research team.

Do you plan to release the object detection training code anytime soon? The memory consumption of this architecture is very compelling..

Hi,
Thank you for your fantastic project.

I've encountered a problem when trying to evaluate the model downloaded from the Huggingface repo given in your project. I'm facing an issue with both the small and tiny vim models. When I loaded the models, I receive the following error message:
"size mismatch for pos_embed: copying a param with shape torch.Size([1, 730, 384]) from checkpoint, the shape in the current model is torch.Size([1, 197, 384])."

Could you please offer some guidance on how to address this problem? Your assistance would be greatly appreciated.

Thank you so much for this matter!

Hello every researcher,
I have researched this code for 3 day, Finally, I can run the test code successfully. below is the test code.
`import torch
from mamba_ssm import Mamba

batch, length, dim = 2, 64, 16
print(torch.cuda.is_available())
x = torch.randn(batch, length, dim).to("cuda")
model = Mamba(
# This module uses roughly 3 * expand * d_model^2 parameters
d_model=dim, # Model dimension d_model
d_state=16, # SSM state expansion factor
d_conv=4, # Local convolution width
expand=2, # Block expansion factor
).to("cuda")
y = model(x)
assert y.shape == x.shape`

Therefore, I would like to share my experiments to help those people are still struggling for the problem of setting environment.

Hi @xinggangw @Unrealluver @ifzhang @LegendBC ,
Thanks for the release of the great work. But, I was trying to understand how I can actually interpret the model such that the results will be more explainable. Using the pretrained image classification weights, I just want to understand whether during training or inference, how can I record the attention weights generated within the BSSM at each time step. I have gone through the mamba_model.py where we have hidden states and residuals. Can I directly use them for understanding of the model predictions or do I need to extract other details using main.py or Mamba_model.py?If yes, what are the different directions that we can look into like saliency maps etc ,. Any suggestions would be highly useful. Thanks in advance.

I got error: namespace "cub" has no member "WarpMask" when installing the mamba, but I have no idea how to solve it, could you give me some advice? Thanks

Thanks for your great works! However, I observe that the training efficiency (including the training speed and memory use) is much lower than that of the plain ViT with a similar mode size. Do you have any insights on this phenomenon?

As the title suggests.

I'd like to be able to load vim models using the timm library if I can

Dear authors,

Thanks for the great work and releasing the codebase! I have one question regarding the Mamba module initialization.

From the code, I see its linear layers are initialized here and here, then the weights and biases are overwritten here and here, which zeros out the mamba linear layers' biases. So this line actually can be deleted? Please share your insights if it's intended. Thanks!

阅读您的代码时发现bimamba有v1和v2版本分别对应BimambaInnerFn和MambaInnerFnNoOutProj；v1对同一个序列分别进行正向forward和反向forward但是采用了相同的proj模块计算B和C，而v2则是定义了两次proj模块（x_proj于x_proj_b）分别计算不同的B,C，请问为什么要这样做呢？以及这两者哪个效果会更好一点？最后mamba中step()这个函数是不是不管训练还是推理时都不会执行，因为step中并没有指明两次计算的过程？非常感谢。😦

Thanks a lot to the authors for the wonderful work. I have some quick questions about the repo.

When installing causal-conv1d and mamba, I encountered an error saying "The detected CUDA version (12.3) mismatches the version that was used to compile PyTorch (11.8). Please make sure to use the same CUDA versions.". Do you know how to address it?

I also tried several different torch and cuda versions (eg tc211+cu121), it seems that sometimes it can be successfully installed but the model training become quite slow. Did you find similar issues about that, or does this repo have a strict constraint of the torch and cuda versions?

Hi there, your vim is impressive! I had a great read of the paper and the code! I am trying to follow the bi-directional mamba but can't find where the code is. I looked https://github.com/hustvl/Vim/blob/main/vim/models_mamba.py

Dear authors:
Hope this issue finds you well!
It seems that I can not get your results without your pretrained model. The url in the following figure is 'to.do', so I hope that the pretrained model will be seen soon.Thanks!

Hello,
I would like to express my appreciation for the outstanding work on this project.

In the original Mamba, there is no existence of the 'z' mechanism as a gate. However, in Vim, an additional 'z' has been incorporated as a gate. Why was it designed this way? What would happen if it were removed?

The code in question can be found at:

Your clarification would be immensely appreciated.

I find your paper on Vision Mamba very interesting. However, when using your code, I encountered a problem (which may well be normal behavior). When analyzing GPU memory consumption and FPS for Vim versions other than Tiny, I could not achieve similar speed and memory improvements. I compared it to DeiT, and the improvements were only visible in Vim-Ti. Am I doing something wrong, or are the improvements only in the Tiny version?

Thanks for the useful repo. I was going through the code, and upon inspection I saw that Vim-T and Vim-S configurations have double the number of blocks (depth=24) whereas both Tiny and Small configurations for ViT/DeiT in timm have depth=12. Is there a reason for this disparity?

Thanks for the great work!
According to the paper, there should be a 'SILU' activation operation in the Vim Block. However, when I check the following code in mamba-1p1p1/mamba_ssm/modules/mamba_simple.py, I didn't find the "activation" operation.

            elif self.bimamba_type == "v2":
                A_b = -torch.exp(self.A_b_log.float())
                out = mamba_inner_fn_no_out_proj(
                    xz,
                    self.conv1d.weight,
                    self.conv1d.bias,
                    self.x_proj.weight,
                    self.dt_proj.weight,
                    A,
                    None,  # input-dependent B
                    None,  # input-dependent C
                    self.D.float(),
                    delta_bias=self.dt_proj.bias.float(),
                    delta_softplus=True,
                )
                out_b = mamba_inner_fn_no_out_proj(
                    xz.flip([-1]),
                    self.conv1d_b.weight,
                    self.conv1d_b.bias,
                    self.x_proj_b.weight,
                    self.dt_proj_b.weight,
                    A_b,
                    None,
                    None,
                    self.D_b.float(),
                    delta_bias=self.dt_proj_b.bias.float(),
                    delta_softplus=True,
                )
                # F.linear(rearrange(out_z, "b d l -> b l d"), out_proj_weight, out_proj_bias)
                if not self.if_devide_out:
                    out = F.linear(rearrange(out + out_b.flip([-1]), "b d l -> b l d"), self.out_proj.weight, self.out_proj.bias)
                else:
                    out = F.linear(rearrange(out + out_b.flip([-1]), "b d l -> b l d") / 2, self.out_proj.weight, self.out_proj.bias)

I further check the mamba_inner_fn_no_out_proj method in MambaInnerFnNoOutProj class in mamba-1p1p1/mamba_ssm/ops/selective_scan_interface.py and CausalConv1dFn class incausal-conv1d/causal_conv1d/causal_conv1d_interface.py. Though there is 'activation' operation occurs in CausalConv1dFn, it seems get a 'None' value.

class MambaInnerFnNoOutProj(torch.autograd.Function):
    def forward(ctx, xz, conv1d_weight, conv1d_bias, x_proj_weight, delta_proj_weight,
                A, B=None, C=None, D=None, delta_bias=None, B_proj_bias=None,
                C_proj_bias=None, delta_softplus=True, checkpoint_lvl=1):
        ...
        conv1d_out = causal_conv1d_cuda.causal_conv1d_fwd(x, conv1d_weight, conv1d_bias,None, True)
        ...

class CausalConv1dFn(torch.autograd.Function):
    @staticmethod
    def forward(ctx, x, weight, bias=None, activation=None):
        if activation not in [None, "silu", "swish"]:
            raise NotImplementedError("activation must be None, silu, or swish")
        if x.stride(2) != 1 and x.stride(1) != 1:
            x = x.contiguous()
        bias = bias.contiguous() if bias is not None else None
        ctx.save_for_backward(x, weight, bias)
        ctx.activation = activation in ["silu", "swish"]
        out = causal_conv1d_cuda.causal_conv1d_fwd(x, weight, bias, ctx.activation)
        return out

My cuda's version is 12.4, the bug appears when I try to install 'causal-conv1d'. it seems this code is only woking based on the cuda is 11.8. Dose anyone use 12.4 cuda running this code properly?

Hi, thanks for releasing! Any plans to add a license? Thx!!

Edit:
Is the tokenizer used different from the one below?
tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neox-20b")

Hello,

I am running this command on an Ubuntu 22.04 LTS system python main.py --finetune '' --eval --resume vim_t_midclstok_76p1acc.pth--model vim_tiny_patch16_224_bimambav2_final_pool_mean_abs_pos_embed_with_midclstok_div2 --data-path imagenet-mini --data-set 'IMNET' in order to try your model, as you suggest in the documentation.

I installed mamba-ssm using pip wheels because your recommended approach does not work, as noted in another issue.

However, it seems that the pretrained model is not loaded correctly as shown in the error message below. What could I do to fix this?
