demo runtime environment issues

[Leonwu0728]

What version of pytorch is required for the environment? When I run the given demo_letr with version 1.10.0, I get the following error, ImportError: cannot import name '_new_empty_tensor' from 'torchvision.ops'.Is there a compatibility problem with my environment so I can't import it?

try torch-1.8.0+cu111, torchvision-0.9.0+cu111, works for me;

If you use torch1.10.0, you can remove that "import" to solve your problem, but you will meet other version-related problem later.

Thanks. It worked when I downgraded the torch version to 1.8.0+cu111.
