hello i have some problems about this code
Traceback (most recent call last):

with open(src, 'rb') as fsrc:
FileNotFoundError: [Errno 2] No such file or directory: '../ISIC/dataset/train_data/ISIC_33.png'

i dont know how to deal with ,can you help me ?thanks a lot

[LeeJunHyun]

Dear @PanPan0210 , I think your directory name is different from mine.

[YangBai1109]

yeah i think so ,could you tell me your directory name ? i didnot find it in the readme.md document

[LeeJunHyun]

In the 'dataset.py' ,

parser.add_argument('--origin_data_path', type=str, default='../ISIC/dataset/ISIC2018_Task1-2_Training_Input')
parser.add_argument('--origin_GT_path', type=str, default='../ISIC/dataset/ISIC2018_Task1_Training_GroundTruth')
    
parser.add_argument('--train_path', type=str, default='./dataset/train/')
parser.add_argument('--train_GT_path', type=str, default='./dataset/train_GT/')
parser.add_argument('--valid_path', type=str, default='./dataset/valid/')
parser.add_argument('--valid_GT_path', type=str, default='./dataset/valid_GT/')
parser.add_argument('--test_path', type=str, default='./dataset/test/')
parser.add_argument('--test_GT_path', type=str, default='./dataset/test_GT/')

'../ISIC/dataset/ISIC2018_Task1-2_Training_Input' is the origin image path,
'../ISIC/dataset/ISIC2018_Task1_Training_GroundTruth' is the origin ground truth path
'./dataset/train/' is the path for split dataset.
'./dataset/train_GT/' is the path for ground truth of split dataset.

hello ,thank you dor your answer ,but i have another problem

RuntimeError: Given groups=1, weight of size [64, 3, 3, 3], expected input[1, 1, 256, 256] to have 3 channels, but got 1 channels instead

how can i solve it ?
i'am so sorry because this is my first study ,so i have a lot questions .

[LeeJunHyun]

It's ok, I think you read the wrong data as a input. (may be ground truth image)

ISIC input image file have RGB 3 channels, but your file has only 1 channel like the gray scale image.

[YangBai1109]

yeah,i just use a gray scale image ,so what should i do to use it?

[LeeJunHyun]

You should use RGB 3 channels images as the input.
You can get the ISIC 2018 RGB images at here or https://challenge2018.isic-archive.com/task1/training/.
I had used this dataset, so you can use my code with these.

[YangBai1109]

so ,i can't use my dataset in this code ?

[LeeJunHyun]

Do you have only 1 channel image?

Then, you should change setting to img_ch=1 at the solver.py#L55.

[YangBai1109]

thank you very much for your help
but how can i save the segmentation result image ?
that is prediction result

[LeeJunHyun]

solver.py#L231 Here is the code for saving images. You can modify this code to save whole images.

[YangBai1109]

thank you very much ;
how can i plot the accuracy and loss curve???

[LeeJunHyun]

I didn't implement the code for plotting a graph, but you can refer here :)

[YangBai1109]

thank you for your help ,
could you tell me how to solve this problem?

i do not know how to solve it

[LeeJunHyun]

I think your pytorch version is not fit with your code.
Or you can change the code for image rotation.

[YangBai1109]

hello,i want to know

Epoch [3/150], Loss: 1130.9463,
[Training] Acc: 0.7911, SE: 0.9983, SP: 0.7911, PC: 0.0002, F1: 0.0004, JS: 0.0002, DC: 0.0004
[Validation] Acc: 0.7926, SE: 1.0000, SP: 0.7926, PC: 0.0002, F1: 0.0004, JS: 0.0002, DC: 0.0004

why the value of 'Loss'is so big ?i do not know if it is a error ?

[LeeJunHyun]

Is it for your own data? or ISIC data?

[YangBai1109]

on my own data ,the loss is very high ,and the result is bad ,

[LeeJunHyun]

then I cannot help you. because I have not any information about your data.
You should check the your data. Sorry :(

[YangBai1109]

thank you ,

[LeeJunHyun]

If you have no further questions, I will close the issue. I hope my answer was helpful.
