Hi,

It seems that our server on UNC is periodically maintained thus it would sometimes be unable to download.

However, the server was rebuilt yesterday (on Oct 19) thus the downloading service might be down for a few days. I am now contacting the admins to recover the functionality.

Best, Hao

Thanks for your kind reply! I am always looking forward to your update.

Hi,

The downloading service is back and you can test it now. Please let me know if you further have issues in accessing them. I will be inactive on Github in the near future thus you can directly reach me for these link issues.

Hello, Mr. Tan!

I am so glad to hear this good news.

However, the UNC link seems still not working. The following is the error messages:

wget https://nlp.cs.unc.edu/data/model_LXRT.pth https://nlp.cs.unc.edu/data/model_LXRT.pth -P snap/pretrained --2021-10-22 11:57:50-- https://nlp.cs.unc.edu/data/model_LXRT.pth Resolving nlp.cs.unc.edu (nlp.cs.unc.edu)... 152.2.128.53 Connecting to nlp.cs.unc.edu (nlp.cs.unc.edu)|152.2.128.53|:443... failed: Connection timed out. Retrying.

I would be highly appreciated if you could repair it.

Thank you!

Hi,

Could you try with wget --no-check-certificate https://nlp.cs.unc.edu/data/model_LXRT.pth.

I will contact the server manager to solve it.

Best, Hao

[BierOne]

Thanks for your reply.

However, It still does not work. Thank you.

[airsplay]

Hmmm, that's strange. It works on my end now. I will check with them to solve it.

[airsplay]

Hi,

We have densely tested the link on our end (from multiple sites) and it works well here. Could you try with the following things?

1. try visiting the website nlp.cs.unc.edu
2. try ping the website by "ping nlp.cs.unc.edu"
3. confirm that your ca-certificates package is up to date

Best, Hao

[BierOne]

Hi, Mr. Hao!

I have tried following your instructions. And I also tested it by using the different networks from China mainland and Hong Kong.

However, the link nlp.cs.unc.edu is still not reachable.

Much appreciated for your kind help.

Best, Yibing

If you can not visit nlp.cs.unc.edu, it is more like a DNS or web caching issue.

For testing DNS, could you try visit http://152.2.128.53/.

For testing web cache, could you try using the incognito mode of the web browser? In that way, it will resolve the potential caching issue.

[BierOne]

Dear Mr. Hao,

Thank you so much for your kind help. I have tried the incognito mode and the ip address. However, it's still not working.

Actually, what I really need is the model pretrained without vqa datasets, which seems only can be downloaded from this link: http://nlp.cs.unc.edu/data/lxrt_noqa/Epoch19_LXRT.pth http://nlp.cs.unc.edu/data/lxrt_noqa/Epoch19_LXRT.pth. I'd highly appreciate it if you could upload this model to your google drive, which is reachable for me.

By the way, I also have a question about the model saved in https://nlp.cs.unc.edu/data/github_pretrain/lxmert20/Epoch20_LXRT.pth https://nlp.cs.unc.edu/data/github_pretrain/lxmert20/Epoch20_LXRT.pth. Is this model pre-trained with the VQA-2.0 val set?

Because I observed many repositories using this pre-trained model on the VQA-CP datasets, where the test set contains many overlapped QA pairs with the VQA-2.0 val set. If so, this should be an unwanted behavior, since their high performance may be obtained by peeking at test sets.

Best regards, Yibing

Hi, Tan!

I finally downloaded the models! Thank you so much for the help.

Could you please tell me if this model (https://nlp.cs.unc.edu/data/github_pretrain/lxmert20/Epoch20_LXRT.pth ) is pre-triained on the VQA validation set? Thank you!
