ImportError: cannot import name '_new_empty_tensor' from 'torchvision.ops'

[Kephone Gaon]

A small tip, in case the future researcher have the similar issue.

my torchvision.__version__ is "0.12.0+cu113"
and this line

CDN/util/misc.py

Line 14 in 71c5702

 if float(torchvision.__version__[:3]) < 0.7: 

should be modified as:

# if float(torchvision.__version__[:3]) < 0.7:
if int(torchvision.__version__.split('.')[1]) < 7:  # my torchvision.__version__ is "0.12.0+cu113"
    from torchvision.ops import _new_empty_tensor
    from torchvision.ops.misc import _output_size

Yes, that's right.
