I am having the following error;

Hi, I noticed that due to some bugs in the older version of IKC, I can't get the same SSIM results in Table 1. Could you please provide the codes about calculating SSIM results in Table 1? I can't find a version of IKC which provides the same SSIM results as in their paper. Thank you!

您好，对于X2的SR，请问怎么生成Gaussian8的kernel，Set5的每张测试图片都需要生成8张不同的LR图片吗

Hi all, has anyone solved the following error message when trying to train DANv2?

group["initial_lr"] * weight for group in self.optimizer.param_groups TypeError: unsupported operand type(s) for *: 'NoneType' and 'int'

It does not appear with DANv1, and I've seen others report the same issue, but there are no solutions to be found.

Hi,DAN is very cool and thanks you for releasing the code!
When I run the test.py in DANv1,I didn't run the generate_mod_blur_LR_bic.py and create_lmdb.py,just set the LR and HR images in options/setting1/xx.yml,such as in setting1_x2.yml:

 test1:
    name: Set5
    mode: LQGT
    dataroot_GT: /datasets/Set5/LR/x2
    dataroot_LQ: /datasets/Set5/HR/x2

But the result of PSNR/SSIM is 35.59dB/0.938,is lower than the results in your paper."37.34/0.9526"
May I ask is that the different setting of the .yml file contribute to the non-ideal results？

How can I only get output from a custom image?

你好，我使用你给出的训练好的model进行test没有问题，但我加载它进行fine-tuning的时候，会出现如下问题，请问是为什么？

训练DANv1时并没有报错，能正常训练，但容易Loss发散；训练DANv2时会出现以上的报错信息，我应该如何修改才能正常训练呢？万分感谢！

Thank you for sharing. I learned a lot from your paper, but I still have a question about the kernel settings. Does the kernel width and its standard deviation mean the same thing? In your paper you mentioned that "During training, the kernel width is uniformly sampled in [0.2, 4.0], [0.2, 3.0] and [0.2, 2.0] for scale factors 4 , 3 and 2 respectively", but I found in your code that the kernels sigma are all set to [0.2, 4.0] for different upsampling rates, so do I need to change this part when retraining if I want to keep the same settings as in your original paper? Thank you very much!

Hi, it's definitely a fantastic work.
About testing on real image, I am confused.
According to your paper, the SR model inferencing on real image is trained with AWGN. However, in codes/config/DANv1/inference.py, SR model is the same with that of setting1.
I also tested it (with inference.py) on image captured by my own device. The result is quite blur.
Is there any misunderstanding.
Thanks a lot.

你好，想问下setting2中train和test的yaml配置中input_pare=15,而在setting1中用10？

请问作者您有遇到这种情况吗？一开始报错找不到pca_matrix.pth路径，我在generate_mod_blur_LR_bic.py里修改路径（../../pca_matrix/DANv1/pca_matrix.pth）之后出现如图的报错。

Thanks for your work so much.
Like the title, I meet the error that loss value is NAN at 22800 iterations (Second time: 29200) suddenly.
Did you have ever met this kind of error?

你好，谢谢你很有意义的工作和代码。但是我有一个问题就是提供的代码中，yaml的训练数据的模式是LQGTKer，但是训练中却是将GT模糊下采样后得到LR_img, ker_map并用他们训练。dataloader中的LQ数据并没有被使用且没有ker_map的lmdb。这样做是为了增加模糊核的随机性么？将LQ GT 和模糊核都做成lmdb而不是在训练的时候生成会不会降低性能，减少训练时间？

抱歉，因为我的英文可能表达的不太准确，我在test Set5数据集x2时，PSNR=28.85，我还是没能找到问题的所在，我可以把我操作的过程说明一下吗？
Step1：设置generate_mod_blur_LR_bic.py

up_scale = 2
mod_scale = 2
sourcedir = '/datasets/Set5'
savedir = '/datasets/DAN/Set5'
'rate_iso' : 1.0

其他的都没有更改,点击Run，生成的四个文件夹，HR和LRblur都是40张图片，不同的siga。
Step2:之后将这两个数据集放入create_lmdb.py

ima_folder = '/datasets/DAN/Set5/HR/x2/*'#../LRblur/x2/*
lmdb_save_path = '/datasets/DAN_lmdb/Set5/HR.lmdb'#../LRblur.lmdb
meta_info = {"name":"Set5"}

其他内容也没有更改，点击Run，HR.lmdb和LRblur.lmdb都有三个文件.
Sept3:分别放入option/test/test_setting1_x2.yml文件中

suffix : x2
scale: 2
pca_matrix_path:'/DAN/pca_matrix/DANv2/pca_aniso_matrix_x2.pth'
datasets:
    test1:
    dataroot_GT: /datasets/DAN_lmdb/Set5/HR.lmdb
    dataroot_LQ: /datasets/DAN_lmdb/Set5/LRblur.lmdb
pretain_model_G: ../../danv2_x2_setting1.pth

结果报了错：

RuntimeError: Expected tensor to have size 144 at dimension1, but got size 121 for argument #2 'batch2'(while checking argument for bmm)

如果将pca_matrix_path改为pca_matrix.pth就可以正常跑程序，但是结果PSNR=28.648437dB，SSIM=0.817695
这个问题我一直没能解决，不知道那里操作有误导致结果和论文中的结果不相同，还请您指正！

PyTorch 1.11 and 1.5. tried both.

Hi, thanks for providing detailed codes and it's a great job!

I'm testing the pretrained model in local on self generated Gaussian 8 testset with kernel size = 21x21.
And I got the performance as below.

Though the local test perf is also excellent, it's different from the reported one (quote from paper).
I'm a little bit confused... Not sure whether there is a mistake made during testing...
Expect for your reply!

It seems pca_aniso_matrix_x4.pth and pca_matrix.pth are identical, while one is anisotropic and the other isotropic. Please check

Thanks for your nice work!
I am a beginner in blind sr, so I do not understand why methods like EDSR are trained under the bicubic downsampling setting while tested under the multiple-degradation setting.
Looking forward to your reply！

I have generated the test dataset according to the test setting1 and test the provided pre-trained model on it. The PNSR results are roughly the same as you have mentioned in Table 1. However, the SSIM is much lower. Could tell me how to solve this issue.

I suppose the params of the network structures need to be modified? Could you pls provide an x2 version yml file? Thanks!

想知道这方法与esrgan相比会不会有观感上的提升

Hi.

Is there any way to run this if I don't have an external GPU?

(I just have an integrated graphics card.)

Thanks.

Hi, it' a wonderful job.
Why two pretrained weights ("danv1_x4_setting1.pth" and "danv1_x4_setting2.pth") are the same?

@greatlog Hello, thanks for your impressive work.
Could you please provide the checkpoint for setting 1?

I'm interested in the great work. But I found the size of blur kernel is not consistent in DANv1 and v2 for setting2 scale 4.
In DANv1 and kernelGAN, the kernel size is 11.
In DANv2, it is 31.
The quantitative results in the paper of DANv2 is the same as those in DANv1 paper except the additional DANv2, which means testing of DANv2 is the same as DANv1. So you train DANv2 with data blurred by kernel 31 and test it with data blurred by kernel 11. Is there something wrong in my understanding?

Hello,

Thank you for this implementation. I would like to train DAN on my own dataset which is in greyscale. So I created a new yml file in options and I set color option to grey. However weight are still of the size [nbkernel, 3, kernelsize, kernelsize] instead of [nbkernel, 1, kernelsize, kernelsize].
Can't we change the number of channel of the weights ? and How ?

Thank you a lot.

作者你好，谢谢你非常不错的工作，
在我训练时大约在60k个iter会出现loss都变成NAN的情况并且按照 issue#8 的解决办法选取checkpoint继续train 但是一段时间后还是会出现loss变为NAN的情况（如下图），似乎无法解决，想请教一下您怎么train让模型收敛到最终的结果的？

Hello. Can your code be used to predict the blur kernel of an input test image, along with the SR output?
Thanks!

Hello, and thanks for making the code available!
I am curious as to what the SR results are when not using the blur kernel during the SR process (for ex., only inputting a delta kernel as the conditional input for the Restorer during the training process). Of course, in this case it won't be possible to estimate the blur kernel.
If you have checked the SR results when not using the blur kernel, it would be great if you could share them!

Hello, DAN is an amazing framework, but I couldn't save the test results when I was testing the real image, I don't know what went wrong, hope to get a reply. thank you.

hello,
I am confused about the generation process of 'kernel_code'.
When calculating the PCA matrix, the code do 'X = X - X_mean.expand_as(X)' before get the PCA matrix.
Then, in 'PCAEncoder', It seems direct projection by 'torch.bmm(
batch_kernel.view((B, 1, H * W)), self.weight.expand((B,) + self.size)
).view((B, -1))' without '- X_mean'.
Did we need '- X_mean'?

Thank you!

Many thanks for your work.
When I tried to test your code by using the default settings, there are some errors. It seems that the mismatch of the output size and the gt size.

Hi, I would like to ask a question about the dataset preparation. I find that in 'train.py', the 'blur_lr_imgs' are generated online, that is to say, they are generated during training process. For those 'blur_lr_img' generated offline, they are only used in validating process. Does that mean I should only run 'python3 codes/scripts/generate_mod_blur_LR_bic.py' for validation dataset not for train dataset? I think it's not clarified very well in this repo.

非常感谢您的工作，我受益匪浅！关于论文，我想请教您是如何设计这个结构的。
在https://www.bilibili.com/video/BV1Zg411c7zn 这个talk第13:35秒，您提到这种迭代求解k和SR的方法在传统方法中很常见，请问您能给一些参考文献吗？

RuntimeError: ../../../checkpoints/DANx4.pth is a zip archive (did you mean to use torch.jit.load()?)

/DAN-master/codes/config/DAN/models/base_model.py", line 96, in load_network
load_net = torch.load(load_path)

Thanks a lot for the code.

I have some questions on this part of the code that appears both in v1 and v2:

It seems that your loss is the combination of SR loss (contained in d_sr) + kernel loss (contained in d_ker) but only for the last step of the Restorer and Estimator since the lines "total_loss += d_ker" and "total_loss += d_sr" are outside the loop.
It leads me to two questions:

• Why are you keeping track of the d_sr and d_ker for the other steps.
• Did you try to use the d_sr and d_ker for each step and is it giving bad results?

Thanks a lot,
Charles
