如何解决数据集camelyon17

[yuu-Wang]

您好，要是想用Camelyon17 ，该怎么编排数据集的结构，DomainBed/domainbed/data/camelyon17/是这样吗，但是它一直显示没找到。Traceback (most recent call last):

Hi, unfortunately I'm an English speaker, but it looks like you're having issues using Camelyon17 because it is not downloaded?

I woudl run this script, with line 304 uncommented to download the dataset: https://github.com/facebookresearch/DomainBed/blob/main/domainbed/scripts/download.py#L304

[yuu-Wang]

Hello, I have already downloaded the dataset through this link, and the path is /root/wangxy/AlignClip/DomainBed/domainbed/data/camelyon17_v1.0/. However, I keep getting an error that says camelyon17 cannot be found. I'm not sure if my file naming is correct, but I successfully ran other datasets like PACS and Officehome. Do I need to handle the camelyon dataset separately?

[piotr-teterwak]

Could you post here the command you use to run main.py, and the directory you run it from? To me it looks like args.root is set to DomainBed/domainbed/data/ instead of '/root/wangxy/AlignClip/DomainBed/domainbed/data/'.

[yuu-Wang]

main.zip
This is the main file, and these are the parameters I need to run: DomainBed/domainbed/data/ -d WILDSCamelyon --task domain_shift --targets 0 -b 36 --lr 5e-6 --epochs 10 --beta 0.5. This is the location where I placed my dataset.

[piotr-teterwak]

Can you run with /root/wangxy/AlignClip/DomainBed/domainbed/data/ -d WILDSCamelyon --task domain_shift --targets 0 -b 36 --lr 5e-6 --epochs 10 --beta 0.5 instead? See the data path in the first parameter.

[yuu-Wang]

Hello, it's running now, but there's a problem. The camelyon17_v1.0 dataset contains raw dataset patches, and the patches are classified in the format patient_00X_node_X, which is necessary for it to work. However, I have already divided the dataset into hospital0, hospital1, hospital2, hospital3, hospital4, and now it's giving an error. Could you please explain why this is happening?

[piotr-teterwak]

Could you post the stack trace so I can have more information?

[yuu-Wang]

Hello, why is the test dataset empty here? I reclassified the camelyon17 dataset and regenerated the metadata.csv file. Do I need to create separate CSV files for test, validation, and training sets?

[piotr-teterwak]

Hi @yuu-Wang ,

It's pretty hard to understand what exactly is going on here without more details. In order to help you, I will need a minimal reproducable example including:

1. How you download the data.
2. How you generate the new metadata.csv file
3. A few lines of code, of how you load the data.

However, taking a quick look, I don't think the images need to be split into directories based on their hpspital source.

hi,
1.The dataset I downloaded is from line 304 of download.py.
(

DomainBed/domainbed/scripts/download.py

Line 304 in dad3ca3

# Camelyon17Dataset(root_dir=args.data_dir, download=True)

)
2.Since I noticed that the WILD environment in the file(

DomainBed/domainbed/datasets.py

Line 348 in dad3ca3

class WILDSCamelyon(WILDSDataset):

) requires four domains (hospital0, hospital1, hospital2, hospital3), I used this code(https://github.com/jameszhou-gl/gpt-4v-distribution-shift/blob/ccfcf00851ccd8867de7c6d92591eaedd8a66d0d/data/process_wilds.py#L21) to divide the downloaded dataset into these four domains.
3.I used this
(https://github.com/thuml/CLIPood/blob/bc0d8745e8b0d97b0873bd8ed8589793abd1c1a7/engine.py#L53)
(https://github.com/thuml/CLIPood/blob/bc0d8745e8b0d97b0873bd8ed8589793abd1c1a7/converter_domainbed.py#L18)
to divide the dataset into training, validation, and test sets.

[piotr-teterwak]

Steps 2 and 3 are not needed; the code takes care of this internally. Could you re-download with step 1, skip steps 2 and 3, and try again? If this does not work, could you please send a few lines of code of how exactly you are loading the dataset in your training code?

[yuu-Wang]

Sure, I downloaded it directly according to step one and then ran main.py
(https://github.com/thuml/CLIPood/blob/bc0d8745e8b0d97b0873bd8ed8589793abd1c1a7/main.py#L104).
Is it only this dataset that exceeds the length?

[piotr-teterwak]

I see that you're running main.py from another repository, CLIPood, and not the DomainBed repository. I'm not very familiar with the CLIPOod code. Could you run from an unmodified DomainBed codebase?

[yuu-Wang]

Thank you very much for your patience. It's doable.
