Certificate has expired

caxelrud

When trying the Transfer Learning tutorial, the step "in the Dataset tab, select the torchvision.datasets category and the CIFAR10 dataset", I got the following error:
"file C:\Users\inter\TorchStudio\python\lib\urllib\request.py, line 1349, in do_open
raise URLError(err)
URLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1129)".

I am using Windows 10.

caxelrud fixed with TorchStudio 0.9.7

Looks like this is an issue with the download server from which the CIFAR10 dataset is downloaded. Can you try again, or from a different computer/connection ? Unfortunately I cannot repro the issue.

Add the following two lines to the source file header:

import ssl
ssl.create_default_https_context = ssl.create_unverified_context

I can't repro the issue here but indeed seems to be the solution. Detailed fix:
edit %USERPROFILE%\TorchStudio\torchstudio\datasetload.py and add these lines at the very beginning of the file:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

Let me know how it goes on your side.
