Can you offer the link for downloading the training data and validation data? Thank you very much

And what's more, the link for testdata: https://drive.google.com/uc?export=download&id=1z_fD3UKgWQyOTZIBbYSaQ-hz4AzUrLC1 failed somehow..

The link for validation data: https://drive.google.com/file/d/1FU7xF8Wl_F8b0tgL0529qg2nZ_RpdVNL/view

Would you mind trying downloading the files manually? I tested it and it still worked for me.

And once the connection is break, we can only download it from the beginning

Can you please host the data somewhere else? Google drive isn't really made for this kind of high traffic stuff:

Sorry, you can't view or download this file at this time.

Too many users have viewed or downloaded this file recently. Please try accessing the file again later. If the file you are trying to access is particularly large or is shared with many people, it may take up to 24 hours to be able to view or download the file. If you still can't access a file after 24 hours, contact your domain administrator.

Berkeley must have a place for you to host it

[PeterWang512]

I see, I'll work on a new download link soon. Sorry that this causes trouble

[PeterWang512]

Sorry for the wait. Currently I'm working on storing the file into a different cloud server, and will update the link when it's available.
In the meantime, I've made a temporary link with splitted training data here: https://drive.google.com/drive/u/2/folders/14E_R19lqIE9JgotGz09fLPQ4NVqlYbVc
Let me know if this works for you, and I'll let you know when a new link is available.

[PeterWang512]

Also made a copy in Box, here's the link: https://cmu.app.box.com/folder/124997172518?s=4syr4womrggfin0tsfhxohaec5dh6n48

Thanks, Box version works for me!

Hey! Can you explain to me the tool you are using to unzip this? I have used multiple tools and the extraction is not happening in the desired format. The exact command you use would be helpful :)

[PeterWang512]

I'm using unzip in ubuntu.

[pratyushmaini]

This does not work for me on the command line. are you sure this is working in the command line

I have also tried other methods like 7za but they do not extract it correctly (the directory structure gets muddled)

[PeterWang512]

Would you mind trying the script here to see if it works? https://github.com/PeterWang512/CNNDetection#download-the-dataset
I tried it again and it works on my end.

[pratyushmaini]

: ~/projects/CNNDetection> $ cd dataset/test
: ~/projects/CNNDetection/dataset/test> $ ls
download_testset.sh
: ~/projects/CNNDetection/dataset/test> $ bash download_testset.sh

[PeterWang512]

Never seen this error before. Doing a quick google search found this: https://askubuntu.com/questions/54904/unzip-error-end-of-central-directory-signature-not-found

[pratyushmaini]

As you can see in the comment I posted, the script downloads just 89936KB of data which is clearly not the test set.

[PeterWang512]

Sorry but not sure if I can help any further if I cannot reproduce the error. Will look into this further if you can provide the exact details for others, including me, to reproduce this.

[pratyushmaini]

Did you try for the train set or for val and test? Now val and test work, but train does not. I think its an issue with where it is hosted that it allows downloading sometimes.

[PeterWang512]

Yes, please try this link and this link for training images. These are the mirrors of the dataset

[pratyushmaini]

Can you tell me the command such as this to do that?
https://stackoverflow.com/questions/46239248/how-to-download-a-file-from-box-using-wget
This and many other links don't work.

[PeterWang512]

Sorry I also haven't figured out a way to download from Box using bash scripts. Would it be possible to download it manually first? Meanwhile, I'll look for other ways to host or download the dataset
