torchvision version detection

[MamoruDS]

Hello, I noticed some problems with the implementation of the code that detects the version of torchvision in utils.misc.py

import torchvision
if float(torchvision.__version__[:3]) < 0.7:
    from torchvision.ops import _new_empty_tensor
    from torchvision.ops.misc import _output_size

This will have a fatal issue for torchvision>=0.10

python -c "import torchvision; print(torchvision.__version__[:3])"
# output equals 0.1
