Can not fetch mnist data set

[ggankhuy]

This example is based on FSDP1 which is deprecated but I still wanna see it working: https://github.com/pytorch/examples/blob/main/mnist/main.py But mnist fetch command failing, I believe here: https://github.com/pytorch/examples/blob/acc295dc7b90714f1bf47f06004fc19a7fe235c4/mnist/main.py#L120C4-L121C44

WIth error output:

mp.spawn(fsdp_main,
