How to build the environment on RTX3090?

[LeryLee]

I followed your settings:

python 3.6
cuda 10.2
nvcc 10.2
pytorch 1.6.0

But I can't install detectron2, I searched many many solutions, but can't make it work.

Sometime it seems to install detectron2 successfully, but I got the error just like #10

KeyError: 'Non-existent config key: OWOD

Then I re-build the detectron2 from the repo, but I got:

ValueError: Unknown CUDA arch (8.6) or GPU not supported

I submit an issue in the original detectron2 repo:
facebookresearch/detectron2#3076

And now I just want to know what is your hardware and software environment in detail, I want to locate where is wrong,
I struggle on this for a whole day, please help me, thank you!

It seems that cuda 10.2 cannot support your GPU. Please see this. I have used P100s and V100s.

Please reopen this issue for further discussions.
