Minor Typo in eval_lvis.py

[minsuk-sung]

Hi,
I've been using the your MDETR and it's been incredibly helpful for my work. Great job on this!

I noticed a small typo in eval_lvis.py at this line:

mdetr/scripts/eval_lvis.py

Line 40 in ea09acc

utils.init_distributed_mode(args)

AS-IS: utils.init_distributed_mode(args)
TO-BE: dist.init_distributed_mode(args)

Just thought to point it out. Thanks for your hard work on this project!

Best,
Minsuk
