Should be fixed now. Would be great if you could confirm. Thanks!

@folke Unfortunately, I just tested it, and now the error is on line 223.

Can you give me some example code?

Can you give me some example code?

It seems that the error occurs because the label field is a table.

Here is an example in python.

import torch

torch.hub.load()

[folke]

test again

[Fau818]

test again

Okay, it's working great now!
