data_size is NAN about dncnn HOT 23 CLOSED

First step, I run GenerateTrainingPatches.m,Second step ,I run Demo_Train_model_64_25_Res_Bnorm_Adam.m to train.But I find data_size is NAN.what's wrong with it?
then I should run Demo_Test_model_64_25_Res_Bnorm_Adam.m?

from dncnn.

By the way,if I just want to validate your code,could I run Demo_test_DnCNN.m directly? But PSNR and SSIM both are NAN.so,could you figure the problem?

from dncnn.

maybe I solved above problem,but I met the follow problem :

>> Demo_test_DnCNN
引用了不存在的字段 'dilate'。

出错 vl_simplenn (line 303)
        'dilate', l.dilate, ...

出错 Demo_test_DnCNN (line 64)
    res    = vl_simplenn(net,input,[],[],'conserveMemory',true,'mode','test');

maybe I solved above problem,but

hello , I run Demo_test_DnCNN.m , But PSNR and SSIM both are NAN.so,could you figure the problem?
and run DnCNN_train ,the result have error and is Input factor is insufficient DnCNN_train(line 75) net = vl_simplenn_tidy(net); can you help me

from dncnn.

I dont have this problem. It seems like you might have some problem with your training. How bout your training error? it should reduce around 1.0.

from dncnn.

what is difference for 1.0 and 1.1? l run the 1.0 also have error.

from dncnn.

l first run Demo_test_DnCNN3.m, the result is -----------------------------------------------

For the NAN problem in version 1.1, you should (1) add the path to 'train400' data, then (2) run 'data\GenerateTrainingPatches.m', so that it will generate the training data for you. The training data is storaged in 'data\TrainingPatches\imdb_40_128.mat'. And please check your training data size 'imdb_40_128.mat' whether you really have the data or not.

thank you very much

from dncnn.

wait , what is (1), 1.1 add or 1.0 add?

from dncnn.

You should add it for TrainingCodes_v1.1 since it doesn't have 'Train400' images in their 'data' folder. The 'Train400' images path is located in 'TrainingCodes_v1.0' folder.

from dncnn.

OK, thank you

Hi, I don't understand how the mat files in model are created. Can you please tell in what sequence the code should run?

from dncnn.

hello. first, you should run Demo_test_DnCNN3. if you use GPU, ni should remove "%net = vl_simplenn_tidy(net);" "%", and if have error, in Demo_test_DnCNN3 add your vl_setupnn path. then run GenerateData_model_64_25_Res_Bnorm_Adam.

I am actually new to deep learning. I didn't get how the models are created as .mat files. We need to run some code and then save it as mat file. Where is this code to create model? Thank you.

I am new to deep learning. how did u you resolve the data_size and data_meme NaN issue? @goonder .

from dncnn.

也许我解决了上面的问题，但我遇到了以下问题：

>> Demo_test_DnCNN
引用了不存在的字段 'dilate'。

出错 vl_simplenn (line 303)
        'dilate', l.dilate, ...

出错 Demo_test_DnCNN (line 64)
    res    = vl_simplenn(net,input,[],[],'conserveMemory',true,'mode','test');

也许我解决了上面的问题，但是

您好，我现在也遇到了同样的问题，请问您是怎么解决的。

How can you solve this problem,could you tell me? I have met the same problem,my datasiaze is also NAN.
