EMNIST download link is broken

[github-actions]

Oh no, something went wrong in the scheduled workflow tests/download.
Please look into it:

https://github.com/pytorch/vision/actions/runs/2027366886

Feel free to close this if this was just a one-off error.

This has happened before and was fixed on their end after a few days. Let's give them a little more time to fix before we act.

Seems to be fixed again as there were no more failures in the last 6 days.

EMNIST is not working again.

    149 # check integrity of downloaded file
    150 if not check_integrity(fpath, md5):
--> 151     raise RuntimeError("File not found or corrupted.")

RuntimeError: File not found or corrupted.

This issue is active again, I checked and the NIST website proposes the following link instead: https://biometrics.nist.gov/cs_links/EMNIST/gzip.zip

This link is working now, thanks!

I ask you a question.
I could download EMINST directly.
https://biometrics.nist.gov/cs_links/EMNIST/gzip.zip
but, I found that I could not download EMINST at Google Colaboratory.
This is the code I used.

import torch
import torchvision

emnist_data = torchvision.datasets.EMNIST(
    './EMNIST', 
    split='balanced',
    train=True, download=True, transform=torchvision.transforms.ToTensor())

data_loader = torch.utils.data.DataLoader(emnist_data, batch_size=100, shuffle=True)

If you know something about Google Colaboratory,could you tell me How can I download it at Google Colaboratory?

Though I never use google lab before, but I suggest you can show the error and find the answer. It is possible google lab shielding some links or download timeout.

Hi all, thanks for the reports. The EMNIST download should be fixed in the next version of torchvision (0.18).
