This is also an updated version of my previous blog
detectron2 published on October 13, 2019. I lost the
previous source for this blog, but, let's re-write it.
The autumn in both Vancouver and Seattle is gorgeous…

Alright, let’s rapidly test Detectron2 .
Installation is detailedly summarized in INSTALL.md .
We can simply follow GETTING_STARTED.md
for some simple demonstrations. Make sure you’ve
downloaded the demo pictures from Detectron1
demo and save under Detectron2’s folder demo.
